BackgroundLung toxicity in patients undergoing cetuximab and radiotherapy (Cetux-RT) for head and neck squamous cell carcinoma (HNSCC) has been reported in literature and represents a serious side effect of concurrent therapies.MethodsWe report a case of a HNSCC patient that developed neck emphysema during the course of Cetux-RT. The patient was an old male (80 years old) in a good performance status, with an oropharyngeal cancer (T4aN3a).ResultsDuring RT, cone-beam computed tomography (CBCT) showed bilateral neck emphysema that was confirmed at restaging CT. We decided to stop the treatment and to treat the neck emphysema with conservative strategies. After one week CT was repeated and the neck emphysema had improved, so we decided to complete the RT treatment.ConclusionsPatients undergoing Cetux-RT must be properly selected, whereas IGRT imaging must be viewed carefully in order to permit an early diagnosis and careful management of the patients.  相似文献

ObjectiveTo describe a patient who, 5 years after total thyroidectomy to treat Graves disease, presented with thyrotoxicosis due to nonmalignant lateral ectopic thyroid tissue.MethodWe describe the laboratory, imaging, and physical findings of the study patient and review the relevant literature.ResultsA 32-year-old white woman with a history of Graves disease presented with recurrent hyperthyroidism 5 years after total thyroidectomy. A radioactive iodine scan was performed, which revealed elevated uptake (40%) and positive imaging in the left mid-neck. Ultrasonography examination of the neck confirmed the absence of any thyroid tissue within the thyroid bed, but documented 2 nodular, hypoechoic left upper-neck masses with punctuate hyperlucency. Contrast-enhanced computed tomography was performed to precisely localize the nodules, which were excised surgically via selective neck dissection. Histopathologic examination revealed chronic lymphocytic inflammatory infiltrate with focal thyroid hyperplasia and papillary infoldings and no evidence of malignancy.ConclusionsTo our knowledge, this represents the first report of ectopic benign thyroid tissue as the sole cause of hyperthyroid symptoms, and this entity should be considered in patients who have undergone thyroidectomy and have persistent hyperthyroidism.

ObjectiveTo describe the case of a previously healthy 56-year-old woman, who presented with acute, nontraumatic pain in the left side of the neck and mild dysphagia.MethodsWe report the results of the physical examination, imaging studies, and clinical laboratory studies. In addition, we describe the patient’s hospital course after surgical intervention.ResultsA patient who sought medical attention because of acute, nontraumatic neck pain and dysphagia was subsequently found to have acute extracapsular hemorrhage of a parathyroid adenoma. Computed tomography and magnetic resonance imaging studies revealed a mass effect beginning in the neck and extending into the mediastinum. Surgical exploration of the neck and histopathologic evaluation confirmed the diagnosis of spontaneous rupture of a parathyroid adenoma with associated hemorrhage.ConclusionExtracapsular hemorrhage of a parathyroid adenoma is rare and necessitates a high index of clinical suspicion for diagnosis. This diagnosis should be considered in a patient who presents with acute anemia, hypercalcemia, and a neck mass. (Endocr Pract. 2012;18: e57-e60)  相似文献

ObjectiveTo determine the best surgical strategy for patients with multiple endocrine neoplasia type 2A (MEN 2A) who have primary hyperparathyroidism (PHPT).MethodsWe performed a systematic literature review and conducted a retrospective cohort study that included patients with PHPT identified from the MEN 2A database at the University Medical Center of Utrecht, Utrecht, the Netherlands, between 1979 and 2009.ResultsThe review describes the course of worldwide parathyroid surgical management in MEN 2A PHPT over the past 75 years, which has evolved from aggressive parathyroid resections to minimally invasive parathyroidectomy (MIP). The study cohort included 20 patients. Primary surgery for parathyroid disease in patients with MEN 2A (n = 16) included MIP (n = 6), conventional neck exploration with resection of enlarged parathyroid gland(s) (n = 4), and resection of 1 or more enlarged gland(s) during total thyroidectomy (n = 6). Thirteen patients were initially cured after the primary operation. Five patients experi enced persistent or recurrent PHPT. After MIP, 1 patient had persistent PHPT, but no patient developed recurrent PHPT during 5 years of follow-up. Five patients had hypoparathyroidism after subtotal or total parathyroidectomy with autotransplantation, but only 1 patient had transient hypoparathyroidism after MIP. One patient had transient recurrent laryngeal nerve injury after MIP.ConclusionsSurgery for PHPT in patients with MEN 2A has evolved from aggressive conventional exploration of all 4 glands to focused MIP, which appears to be a feasible approach. MIP has low rates of persistent and recurrent PHPT, and the complications are minimal. (Endocr Pract. 2011;17:7-15)  相似文献

ObjectiveIn cases of multinodular goiter with negative cytologic result, reasonable management options include surgical treatment, simple follow-up, or more recently introduced conservative therapies such as laser or radiofrequency ablation, and recombinant human thyroid-stimulating hormone-augmented radioiodine. For patients who are eligible for follow-up or nonsurgical treatments, the possibility that they may have an undiagnosed malignancy (false-negative [FN]-fine-needle aspiration cytology [FNAC] result or incidental thyroid cancer [ITC]) should be considered. The aim of our study was to assess the risk of malignancy in patients known to have presumably benign thyroid disease.MethodsSurgical series of patients who underwent total thyroidectomy for benign disease between 2000 and 2010 at two Italian centers were reviewed. Patients with any preoperative suspicion of malignancy were excluded.ResultsHistologic examination revealed that 84 of 970 (8.6%) thyroidectomized patients had malignancy (5% ITC and 3.6% FN-FNAC), with 89.8% of ITCs having a diameter <10 mm, and 65.7% of FN-FNAC cancers having a diameter >30 mm. Sixty-seven thyroid malignancy patients (79.8%) had stage I disease (American Joint Committee on Cancer criteria). The risk of FN-FNAC increases with increasing size of the nodule, while the risk of ITC increases as nodule size decreases.ResultsThe risk of malignancy in presumably benign thyroid disease cannot be overlooked, but can be minimized through skillfully performed ultrasonography (US) examination and FNAC. Once a patient with multinodular goiter is referred for follow-up or nonsurgical therapy, careful US surveillance is mandatory. (Endocr Pract. 2013;19:444-450)  相似文献

ObjectiveTo describe a case of papillary carcinoma of the thyroid with fibromatosislike stroma, emphasize the need for a diligent search for papillary thyroid cancer in the presence of a fibroproliferative lesion, highlight the peculiar hormonal response of the stromal component, and review the pertinent literature.MethodsWe present the clinical, laboratory, radiologic, and pathologic findings in a patient with papillary carcinoma of the thyroid with fibromatosislike stroma and review the related published material.ResultsA 29-year-old woman presented to our surgical department because of a large mediastinal mass. She underwent surgical removal of the mass by means of a median sternotomy and neck extension. Pathology examination revealed macroscopically tan scarlike tissue, which by histologic study consisted of a dominant fibroproliferative lesion overshadowing a minor component of papillary carcinoma of the thyroid. Further neck exploration with total thyroidectomy revealed multifocal papillary carcinoma of the thyroid. Postoperatively, the patient received radioiodine treatment. A local and aggressive recurrent tumor was observed during a subsequent pregnancy; the lesion was not amenable to complete resection but fascinatingly responded to antiestrogen therapy (orally administered tamoxifen).ConclusionThe presence of a fibroproliferative lesion could be misleading. A diligent search should be made for a papillary thyroid carcinoma component within fibromatosislike stroma. The mode of manifestation of the tumor and its response to hormonal manipulation are distinctive features of this case. (Endocr Pract. 2010;16:650-655)  相似文献

ObjectiveTo describe a patient with a bronchogenic cyst that was erroneously diagnosed as an adrenal tumor and the surgical management strategy to address the operative challenges.MethodsWe summarize the clinical presentation, diagnostic workup, surgical management, and pathologic features of the study patient and review the pertinent literature.ResultsIn this report, we present the case of a 23-year-old woman who underwent retroperitoneoscopic exploration after imaging identified an enlarging left adrenal lesion. Preoperative biochemical testing confirmed that the mass was nonfunctional. No lesion was found after a thorough retroperitoneoscopic exploration under standard high insufflation pressure. Serendipitously, low-pressure inspection for hemostasis after failed exploration enabled discovery of an intradiaphragmatic mass that proved to be a bronchogenic cyst rather than an adrenal tumor. Not only was this a difficult operative dilemma, but it was also an unusual presentation for this tumor.ConclusionsDiscovery of a retroperitoneal or intradiaphragmatic bronchogenic cyst is a rare occurrence. The unusual location and tumor characteristics contributed to near surgical failure. The fortuitous surgical strategy of lowpressure inspection allowed visualization of the tumor for definitive resection. (Endocr Pract. 2012;18:e102-e105)  相似文献

ObjectiveTo describe a patient with papillary thyroid carcinoma who had measurable thyroglobulin (Tg) levels for 20 years without clinical or imaging evidence of a malignant lesion.MethodsWe reviewed the clinical course, pathologic findings, Tg measurements, and results of various imaging studies in our patient and reviewed the literature regarding Tg-positive, diagnostic total-body radioiodine scan-negative patients with thyroid cancer.ResultsFour months after a 3.5- by 3.5-cm follicular thyroid cancer was removed from the anterior neck area of a 5-year-old girl, a bilateral subtotal thyroidectomy was performed. At age 12 years, she presented with a 2-cm mass on the right side of the neck. After a completion thyroidectomy, recurrent mixed papillary-follicular thyroid cancer was found scattered throughout the remaining thyroid parenchyma. Although a postoperative diagnostic total-body radioiodine scan did not reveal uptake of 131I, the Tg level was 58 ng/mL. Despite Tg levels as high as 2,528 ng/mL, the patient had no clinical evidence of thyroid cancer during a 20-year period of follow-up. Moreover, numerous imaging studies, including total-body scanning after the administration of 150 mCi of 131I and [18F]fluorodeoxyglucose positron emission tomography, were negative. Review of pathologic specimens from both operations with use of updated diagnostic criteria indicated that the tumor was a papillary thyroid carcinoma.ConclusionOur observations and the observations of other investigators indicate that some thyroid cancers produce Tg so efficiently that high levels of Tg may be associated with tumors that remain too small to be detected by imaging studies. The Tg levels may remain stable, decline, or even disappear over time without treatment. (Endocr Pract. 2005;11:43-48)  相似文献

ObjectiveTo describe a patient with metastatic thyroid cancer who developed Graves ophthalmopathy after treatment with radioiodine (I 131) and external beam radiation.MethodsWe present a case report that includes clinical, laboratory, and radiologic findings and a brief review of the literature.ResultsA 49-year-old woman who had had a total thyroidectomy and neck dissection followed by I 131 treatment 5 years earlier for papillary thyroid cancer presented for follow-up management after recent neck dissection for recurrent disease. Because she had thyroglobulin antibodies, she was again treated with I 131 after preparation with recombinant human thyroid-stimulating hormone. A post-treatment scan revealed uptake in the right iliac crest. A fludeoxyglucose F 18 positron emission tomography/computed tomography fusion scan revealed osseous metastases in the right pelvis, and external beam radiotherapy was delivered to this area. Approximately 5 months later, she developed periocular swelling and excessive tearing. Magnetic resonance imaging of the orbits revealed enlargement of the extraocular muscles. Serum thyroid-stimulating immunoglobulins were greatly elevated.ConclusionThis case corroborates an earlier report to suggest that radiation-associated thyroid injury in a patient with thyroid cancer may be followed by Graves ophthalmopathy and appearance of thyroid-stimulating immune-globulins in the serum.

ObjectiveTo evaluate the effectiveness of gamma probe performed with technetium Tc 99m–labeled pertechnetate in patients who underwent completion thyroidectomy after pathologic detection of incidental thyroid cancer following subtotal thyroidectomy.MethodsIn this prospective study, we evaluated findings from patients with multinodular goiter who underwent gamma probe–guided lateral approach completion thyroidectomy after the pathologic detection of incidental thyroid cancer following subtotal thyroidectomy where partial thyroid tissue was left unilaterally or bilaterally. Patients who underwent the procedure between January 2003 and January 2007 were included. Thyroid scintigraphy; thyroid and neck ultrasonography examinations; and concentrations of thyroid hormones, thyrotropin (TSH), thyroglobulin, and thyroglobulin antibodies were evaluated before the second operation. Patients were administered 3 mCi technetium Tc 99m pertechnetate during anaesthetic induction, and we extracted suspicious thyroid tissue and tissue with activity above background activity levels according to gamma probe. Extracted tissues were evaluated pathologically.ResultsCompletion thyroidectomy was performed in 23 patients. Seventy-nine tissue samples were extracted; 49 were thyroid tissue and 30 were nonthyroid tissue. Mean thyroid tissue to background activity ratio (T:B) was 6.4 ± 3.9 (range, 2-14.3), and mean thyroid bed (after excision) to background activity ratio (Tbed:B) was 1.2 ± 0.2 (range, 0.8-1.7) (P = .001). Mean T:B and Tbed:B ratios of the nonthyroid tissue were 1.2 ± 0.3 (range, 0.2-1.7) and 1.1 ± 0.2 (range, 0.4-1.4), respectively (P = .001). The thyroid tissue T:B ratio was significantly higher than that of nonthyroid tissue (P < .001). Gamma probe labeling contributed to extraction of small amounts of thyroid tissue that could not be viewed by scintigraphy in 43% of patients.ConclusionsUsing gamma labeling, thyroid tissue shows significantly more activity than nonthyroid tissue. Gamma probe helps detect small, residual thyroid tissue that is buried in the scar tissue that cannot be distinguished by scintigraphy; therefore, it assists in the extraction of the maximum amount of thyroid tissue.

ObjectiveTo describe the clinical manifestations of insulin allergy and explain a systematic management approach.MethodsWe present the clinical, laboratory, and pathologic findings of a type 1 diabetic patient with allergy to subcutaneous insulin and briefly review the related literature.ResultsAn 18-year old woman with type 1 diabetes mellitus had an insulin allergy and developed subcutaneous nodules after insulin administration. Human and analogue insulins were used, but painful nodule formation persisted. Treatment with antihistamines, steroids, and omalizumab and insulin desensitization were ineffective. The patient required pancreatic transplant because glycemic control could not be achieved due to the insulin allergy.ConclusionsInsulin allergy is not a common condition and can be challenging in patients with type 1 diabetes. Therefore, identifying patients with true insulin allergy and applying a stepwise approach to their treatment is important. (Endocr Pract. 2011;17:91-94)  相似文献

ObjectiveTo evaluate the occurrence of thyroid disease in patients undergoing parathyroidectomy for primary hyperparathyroidism.MethodsIn this case series, records of all patients with a diagnosis of primary hyperparathyroidism who underwent parathyroidectomy between January 2005 and December 2008 in our clinic were analyzed retrospectively. Preoperatively, all patients were evaluated with ultrasonography and parathyroid scintigraphy; when needed, thyroid scintigraphy and ultrasound-guided fine-needle aspiration biopsy (FNAB) were used. All patients underwent standard neck exploration. Postoperative histopathologic findings of thyroid tissue were classified as nodular/ multinodular hyperplasia, Hashimoto thyroiditis, papillary thyroid carcinoma, or normal.ResultsFifty-one women and 9 men were included. In the 60 patients, preoperative ultrasonography revealed thyroiditis (without nodules) in 13 (22%), a solitary nodule in 9 (15%) (coexistent with thyroiditis in 7 patients), multinodular goiter in 24 (40%) (coexistent with thyroiditis in 5 patients), and normal findings in 14 (23%). Rates of thyroiditis and nodular goiter were 42% and 55%, respectively. Collectively, prevalence of thyroid disease was 77%. Total thyroidectomy was performed in 27 patients, and hemithyroidectomy was performed in 15 patients. Indications for total thyroidectomy were nondiagnostic or suspicious FNAB results in 5 patients, hyperthyroidism in 4 patients, ultrasonography findings in 11 patients, and intraoperatively recognized suspicious nodularity in 7 patients. Postoperatively, thyroid carcinoma was diagnosed in 9 patients (15%).ConclusionsThyroid disease, particularly thyroid carcinoma, is common in patients with primary hyperparathyroidism. This association should be considered when selecting the surgical procedure. Intraoperative evaluation of the thyroid is as important as preoperative evaluation with ultrasonography and FNAB in patients with thyroid disease and primary hyperparathyroidism.

ObjectiveTo determine whether close collaboration between a neck ultrasound–certified endocrinologist and a skilled endocrine surgeon can optimize minimally invasive radio-guided parathyroidectomy (MIRP) surgical outcomes.MethodsOutcome data were collected on patients with primary hyperparathyroidism whom we intended to treat with MIRP at the induction of anesthesia between October 1, 2005, and December 31, 2007. Patients underwent preoperative gamma camera sestamibi scanning (GCSS), intraoperative gamma probe sestamibi scanning (IOSS), and preoperative neck ultrasonography. Intraoperative parathyroid hormone (PTH) monitoring was performed. Postoperative surgical success was defined as a serum calcium concentration between 8.0 and 10.4 mg/dL within 4 weeks of surgery.ResultsDuring the study period, MIRP was planned for 46 patients. Of the 46 patients, 39 had preoperative neck ultrasonography; 7 underwent evaluation by an endocrinologist or internist who was not ultrasound certified and they therefore did not undergo preoperative ultrasonography. IOSS correctly identified 1 adenomatous gland in 38 of 46 patients (83%), while GCSS correctly localized 1 adenomatous gland in 30 of 46 patients (65%). In 11 GCSS–negative patients, IOSS identified the abnormal gland in 7 (64%), while ultrasonography identified the abnormal gland in 8 (73%). The surgical approach was converted to traditional parathyroidectomy in 3 patients. Every patient exhibited at least a 51% drop in intraoperative PTH levels with resection of the final adenoma; average decrement for the entire group was 79 ± 8% from the highest baseline level. Forty-five patients (98%) demonstrated sustained normalization of serum calcium within several days of surgery.ConclusionA collaborative endocrinology and surgical endocrine oncology practice arrangement, emphasizing careful preoperative physician-supervised neck ultrasonography and the use of intraoperative PTH measurement, optimizes MIRP outcomes.

ObjectiveTo report a case of nonfunctioning parathyroid carcinoma that was incidentally found during a thyroidectomy for multinodular goiter.MethodsWe present a case report, detailing the clinical course and histologic findings in a patient with a nonfunctional parathyroid carcinoma. The related literature is also reviewed.ResultsA 67-year-old woman presented with a 30-year history of a multinodular goiter that was symptomatic. A total thyroidectomy was performed. Histologic examination revealed not only a multinodular thyroid but also a mass in the left lobe, which was diagnostic of a parathyroid carcinoma. Serum calcium and parathyroid hormone levels were normal postoperatively. Eleven months after the initial operation, a suprasternal mass developed, and she underwent neck reexploration and subtotal resection of an invasive recurrent nonfunctioning parathyroid carcinoma. The serum parathyroid hormone and calcium levels were normal before and after the operation. Postoperatively, the patient underwent radiation therapy. Twenty-three months after the initial operation, a computed tomographic scan of the chest revealed an interval increase in size of a nodule in the left lower lobe of the lung, and 30 months after her initial operation, she underwent resection of an isolated, 1-cm (greatest diameter), metastatic parathyroid carcinoma in the left lower lobe of the lung. The patient is currently doing well without evidence of recurrent disease.ConclusionNonfunctioning parathyroid carcinomas are difficult to diagnose and to treat. Recurrent disease after operation is common, and radiation therapy may help stabilize tumor growth. Patients with nonfunctioning parathyroid carcinomas appear to have a poorer prognosis than do those with functioning parathyroid cancers. (Endocr Pract. 2007;13:750-757)  相似文献

ObjectiveTo define a rational, cost-effective, simple approach to managing most patients with papillary thyroid cancer (PTC) who are at low-risk of either cause-specific mortality or tumor recurrence.MethodsTaking advantage of the collective experience of a cohort of 2512 patients with PTC who had initial definitive treatment at the Mayo Clinic in Rochester, Minnesota, between 1940 and 2000, a 5-step approach to the management of low-risk PTC has been devised. This program is based on appropriate preoperative ultrasound localization of neck disease and potentially curative surgery consisting of near-total or total thyroidectomy, with appropriate neck nodal exploration and resection.ResultsThe emphasis of the present program is on the extent of initial surgery, where optimal care is ascribed to a near-total thyroidectomy with curative intent and appropriate neck nodal resection as predicated by appropriate preoperative ultrasonography evaluation of regional lymph nodes. Radioiodine remnant ablation (RRA) is not applicable to patients with PTC who are defined on the day of definitive initial surgery to be at low risk as defined by a metastasis, age, completeness of resection, invasion, and size (MACIS) score of less than 6.ConclusionThe outlook for patients with low-risk PTC is very optimistic, with rates at 30 postoperative years of only 1% for cause-specific mortality and less than 15% for tumor recurrence at any site. The long-term results obtained by potentially curative bilateral resection, appropriate regional lymph nodal excision, and selective use of RRA are excellent. Realistically improving these acceptably low rates for cause-specific mortality and tumor recurrence may be difficult. (Endocr Pract. 2007;13:521-533)  相似文献

ObjectiveWe describe a young woman with previously undiagnosed thyrotoxicosis who presented with acute liver failure (ALF).MethodsWe present a case report and review the relevant literature.ResultsAn extensive evaluation excluded possible causes of ALF other than thyrotoxicosis. The management of thyrotoxicosis posed several unique challenges in the setting of ALF, particularly because we did not want to use potentially hepatotoxic thionamides. The patient was treated with prednisone and propranolol and was started on potassium iodide when she was listed for liver transplantation. She underwent an uncomplicated liver transplant and subsequent thyroidectomy and is doing well.ConclusionThis well-characterized case describes thyrotoxicosis as a possible cause of ALF after thoroughly excluding other possible causes and illustrates the challenges of simultaneously managing both disorders. To our knowledge, this is the first report of ALF possibly resulting from untreated thyrotoxicosis that was successfully treated with liver transplantation. (Endocr Pract. 2013;19:e57-e60)  相似文献

Objective: Whether or not autoimmune thyroid disease influences the progression of differentiated thyroid cancer (DTC) remains controversial. Findings of previous studies are influenced by lead time bias and/or procedure bias selection. These biases can be reduced by studying a single-institution patient population that underwent a similar extent of surgical resection.Methods: From a cohort of 660 patients with DTC who underwent thyroidectomy, we retrospectively studied 357 patients who underwent total thyroidectomy and central compartment node dissection (CCND) for DTC between 2003 and 2013.Results: Forty-one percent (140/345) of study patients had lymphocytic thyroiditis (LT), and 30% (91/301) had serum positive for thyroglobulin antibody (TgAb). LT was reported in 78% of the TgAb-positive cases. Sixty percent (213/357) of cases had metastatic thyroid carcinoma in 1 or more neck lymph nodes (55% [198/357] central compartment, and 22% [77/356] lateral compartment). Patients with LT had fewer metastatic cervical lymph nodes than those with no LT (2.7 ± 4.7 vs 3.5 ± 4.8, respectively, P = .0285). Patients with positive TgAb and thyroiditis had a larger number of benign cervical lymph nodes removed than those with negative TgAb or no LT. No significant difference was observed in age, tumor size, multifocality, extrathyroidal extension, vascular invasion, or frequency of cervical lymph node metastasis between TgAb-negative and -positive cases or between cases with and without LT.Conclusion: Lymphocytic thyroiditis is associated with fewer central neck compartment metastatic lymph nodes and a larger number of excised reactive benign cervical lymph nodes. Whether this association indicates a protective role of thyroid autoimmunity in lymph node spreading remains unclear.Abbreviations:CCND = central compartment node dissectionDTC = differentiated thyroid cancerHT = Hashimoto thyroiditisLT = lymphocytic thyroiditisTgAb = thyroglobulin antibodyTPO = thyroid peroxidase  相似文献

ObjectiveTo report an unusual case of persistent thyrotoxicosis after treatment of Graves’ disease, because of coexistence of struma ovarii.MethodsWe report the clinical history, imaging studies, laboratory and pathologic data, and treatment in a patient with persistent hyperthyroidism after surgical treatment of Graves’ disease. In addition, we discuss some aspects of the pathogenesis of hyperthyroidism due to functioning struma ovarii.ResultsA 42-year-old woman underwent near-total thyroidectomy for treatment of Graves’ disease. Post-operatively, hyperthyroidism was still present. Methimazole was administered again, and performance of a 131I whole-body scan demonstrated a focus of intense uptake in the pelvis. Pelvic ultrasonography revealed a mass (11 by 8 by 7.1 cm) arising from the right ovary, with both solid and cystic components. Abdominal surgical exploration was performed, and the final histologic diagnosis was struma ovarii. The symptoms of hyperthyroidism diminished, and 3 weeks postoperatively, the thyroid hormone levels were in the hypothyroid range.ConclusionIn patients with refractory hyperthyroidism after thyroid surgical treatment, radioiodine scanning should be performed to diagnose or exclude the functioning profile of ovarian masses.

ObjectiveTo report an unusual clinical scenario and a rare histopathologic finding of Hürthle cell thyroid carcinoma in a patient with an autonomous thyroid nodule.MethodsWe describe the presentation and clinical course leading to the surprising histopathologic diagnosis of Hürthle cell carcinoma in a pediatric patient who was diagnosed with hyperthyroidism presenting as a solitary toxic nodule.ResultsA 13-year-old white girl presented with a recent history of a palpable thyroid nodule during a routine primary care clinic visit. She was asymptomatic, and thyroid function tests revealed a suppressed thyrotropin concentration, high-normal free thyroxine concentration, and elevated triiodothyronine concentration. The patient underwent dedicated thyroid ultrasonography revealing a 3.5-cm complex mass in the left lobe with increased central vascularity. Iodine 123 imaging of the thyroid demonstrated homogenous, hyperintense activity in the left lobe. The right lobe was not visualized. A solitary toxic nodule was diagnosed, and, considering her age, she was referred for surgical management. The patient underwent a left lobectomy with isthmusectomy. Pathologic examination revealed a 5-cm, encapsulated, well-differentiated Hürthle cell carcinoma with negative margins and no lymphovascular invasion. The patient underwent subsequent completion thyroidectomy with no evidence of residual carcinoma in the right thyroid lobe.ConclusionsMalignancy in autonomously functioning thyroid nodules is rare. Most of the thyroid nodules presenting as “hot” on radioiodine scintigraphy are benign follicular adenomas. However, this case represents a rare clinical entity, and it highlights the need for clinicians to be vigilant and aware that occasionally carcinomas can masquerade as scintigraphic “hot” nodules.

ObjectiveTo present a case of tall-cell variant (TCV) papillary thyroid carcinoma (PTC) arising from Struma ovarii (SO) and to discuss special considerations in the management of this patient.MethodsThe clinical presentation and relevant pathologic features of a patient with PTC-TCV developing from SO are described, and a concise review of literature regarding this topic is also presented.ResultsA 36-year-old woman with a history of stable right ovarian dermoid cyst presented with amenorrhea and was found to have a significantly enlarged right ovary with multiple cysts. Following laparoscopic cystectomy, pathology revealed mature cystic teratoma (SO) with associated PTC-TCV. Based on this finding, she underwent right salpingo-oophorectomy, right pelvic lymph node dissection, and partial omentectomy. Pathology was negative for extra-ovarian disease, and her tumor was staged as pT1pN0M0. Total thyroidectomy was performed in preparation for radioactive iodine (RAI) therapy. A diagnostic iodine-131 (I-131) scan showed residual uptake in the neck with faint uptake in the lower left quadrant of the abdomen and was followed by therapy with 90 mCi of I-131. The patient had an unremarkable course with no clinical or biochemical evidence of disease recurrence to date.ConclusionsThis is to our knowledge the first reported case of TCV-PTC arising from SO. The presence of this aggressive variant of PTC factored into our decision to proceed with thyroidectomy and I-131 ablation, despite the lack of conclusive evidence in the literature. Recent discoveries on the natural history of thyroid-derived TCV-PTC were critical in choosing the appropriate management for this patient’s disease. (Endocr Pract. 2014;20:e24-e27)  相似文献
