ObjectiveTo report a case of oncocytoma, a relatively rare adrenal tumor, which most commonly is detected as an adrenal incidentaloma.MethodsWe present a case report, including laboratory, imaging, and pathologic findings, of a 47-year-old obese woman who had hypertension and an incidentally found large, left adrenal mass.ResultsOn the basis of the hormonal evaluation, this mass was a nonsecreting adrenal tumor, which histologically proved to be an oncocytoma with borderline malignant characteristics. A collective analysis of the few cases of adrenal oncocytoma published in the medical literature showed that our case corresponded to the previously published cases in preponderant location (left side) as well as the general size (11.4 cm in the largest dimension) and weight (372 g).ConclusionAdrenal oncocytoma should be included in the differential diagnosis of adrenal incidentalomas, especially if large tumors are detected. In addition, a longterm follow-up is suggested because there are no certain clues about the true potential of this tumor. (Endocr Pract. 2010;16:641-645)  相似文献

ObjectiveTo discuss the initial clinical manifestations of primary pigmented nodular adrenocortical disease.MethodsWe present a case report of a 4-year-old boy who had the classic clinical features of Cushing syndrome. Results of hormonal investigations are reviewed, and histopathologic findings are illustrated.ResultsInvestigations revealed adrenocorticotropic hormone (corticotropin)-independent Cushing syndrome. Findings on magnetic resonance imaging of the pituitary gland and abdomen were within normal limits. The patient underwent bilateral adrenalectomy. The histopathologic features were consistent with primary pigmented nodular adrenocortical disease.ConclusionPrimary pigmented nodular adrenocortical disease should be suspected in patients with corticotropin- independent Cushing syndrome who have normal findings on adrenal imaging.

ObjectiveTo present the case of a man with a rightsided adrenocortical carcinoma that invaded the inferior vena cava and was managed by radical resection and vein patch repair.MethodsWe report the clinical, laboratory, imaging, and operative findings, and we highlight the pertinent features of this case. The literature is reviewed for the management of adrenocortical carcinoma in conjunction with inferior vena cava invasion.ResultsIn a 34-year-old man with new-onset abdominal pain, abdominal imaging disclosed a large right adrenal mass with invasion into the inferior vena cava. Laboratory values revealed that the adrenal mass was likely nonfunctional. At surgical intervention with use of cardiopulmonary bypass, the mass was removed en bloc with the adrenal gland, right kidney, and the wall of the inferior vena cava, and the inferior vena cava was reconstructed with bovine pericardium.ConclusionDespite direct invasion or extension of tumor thrombus into the inferior vena cava (or both), complete (R0) resection can be obtained. Thus, this scenario should not preclude attempted curative resection in patients with adrenal cancer. (Endocr Pract. 2008;14: 721-725)  相似文献

ObjectiveTo report a case of a retroperitoneal cystic teratoma that obscured and compressed the adrenal gland, mimicking a primary adrenal tumor.MethodsThe presenting manifestations, radiographic characteristics, gross and microscopic pathologic features, and results of surgical therapy and long-term follow-up are described.ResultsA 50-year-old African American woman with a 2-year history of low back pain and night sweats had a computed tomographic scan of the abdomen, which revealed an incidental 8 by 4 by 3.5-cm left adrenal mass without a clear plane between the mass and the left crus of the diaphragm. Laboratory studies excluded a functioning adrenal tumor. The tumor was resected laparoscopically. It was compressing but not involving the adrenal gland, nor was it involving the diaphragm. Microscopic evaluation revealed a benign mature cystic teratoma characterized by cystic spaces lined by respiratory epithelium with cartilage, bone, lymphoid tissue, smooth muscle, and ganglionic tissue in the cyst wall. The patient had an uneventful postoperative course and is free of recurrence after 18 months of follow-up.ConclusionAlthough rare, a mature cystic teratoma of the retroperitoneum that compresses the normal adrenal gland may masquerade as a primary adrenal tumor and should be included in the differential diagnosis of a nonfunctioning adrenal incidentaloma.

ObjectiveTo evaluate the cause and the clinical and laboratory features of adrenal incidentalomas (AI) in 52 patients and to assess the evolution of nonsurgically treated lesions during long-term follow-up.MethodsWe retrospectively analyzed the medical records of 52 patients with AI undergoing routine followup in 2 Brazilian endocrine centers.ResultsIn our study group, nonfunctioning adenomas were the most frequent cause of AI (42%), followed by cortisol-secreting adenomas (15%), metastatic disease (10%), pheochromocytomas (8%), myelolipomas (6%), cysts (6%), carcinomas (4%), lymphomas (4%), tuberculosis (4%), and aldosteronoma (2%). Only 13 lesions (25%) were functioning (8 cortisol-secreting adenomas, 4 pheochromocytomas, and 1 aldosteronoma). Carcinomas were the largest adrenal masses (mean diameter, 11.7 ± 1.3 cm). With the exception of 1 pheochromocytoma, 1 cyst, and 1 myelolipoma, all AI larger than 6 cm were carcinomas. During follow-up of 21 patients with nonsurgically treated AI for 6 to 36 months (mean, 24.8 ± 8.9), no patient had tumor reduction or disappearance. After 12 months of follow-up, however, a 45-year-old woman had adrenal mass enlargement from 3.2 cm to 4.4 cm; the excised lesion proved to be an adenoma. Moreover, evidence of cortisol hypersecretion developed after 24 months of follow-up in a 30-year-old man with a 3.5-cm adenoma in the left adrenal gland.ConclusionOur findings demonstrate that most AI are nonfunctioning benign lesions and emphasize the need for long-term follow-up of patients with conservatively managed lesions, in light of the potential for evolution to hormonal hypersecretion or tumor growth.

ObjectiveTo report the case of a 78-year-old woman with mixed corticomedullary carcinoma of the adrenal gland, and to review other reported lesions that exhibit clinical and/or histopathologic features of both adrenal cortical and medullary differentiation.MethodsWe describe the patient’s clinical findings and laboratory test results, as well as the gross and histopathologic features of her tumor. We also review the literature pertaining to mixed corticomedullary adenomas and cortical tumors with clinical features of pheochromocytoma, and vice versa.ResultsA 78-year-old woman with a 10-cm left adrenal mass was hospitalized for management of hypertensiveurgency. Laboratory workup revealed elevated urinary metanephrine excretion and elevated serum dehydroepiandrosterone sulfate levels. She underwent left adrenalectomy. Pathologic examination of the lesion showed mixed cortical and medullary histologic characteristics, as well as gross and microscopic evidence of malignancy. Including the present case, we identified 17 cases of neoplasms that exhibit features of mixed corticomedullary differentiation.ConclusionsThis report represents the first documented case of mixed corticomedullary carcinoma. Several benign lesions combine clinical, biochemical, and/or histopathologic evidence of both adrenal cortical and medullary differentiation, including mixed corticomedullary adenomas and corticotropin-secreting pheochromocytomas. The differential diagnosis of a lesion with mixed cortical and medullary features should also include a malignant neoplasm. (Endocr Pract. 2012;18:e37-e42)  相似文献

ObjectiveTo report a case of an incidentally identified adrenal lipoma in a 68-year-old man with flank pain and hypertension.MethodsThe clinical, computed tomographic, and magnetic resonance imaging findings in this patient are described, and the pathologic features of the tumor are characterized. Moreover, the related literature is reviewed and summarized.ResultsThe patient had undergone coronary artery bypass grafting, had a prosthetic heart valve, and required systemic anticoagulation. Computed tomography showed a well-circumscribed left adrenal lesion with evidence of scattered foci of macroscopic fat; these findings were confirmed on magnetic resonance imaging. After laparoscopic left adrenalectomy, pathologic examination revealed a well-circumscribed, fatty, 7-cm adrenocortical-based tumor, which weighed 135 g. Histologic sampling disclosed mature adipose tissue without evidence of myeloid heterotopy or features of malignant involvement, and adrenal lipoma was diagnosed. On the basis of our review of the English-language literature, this tumor is the 11th reported case of adrenal lipoma. The vast majority of these tumors have been asymptomatic and identified incidentally on imaging or at autopsy. A minority of patients have had a history of hypertension.ConclusionWith the increased utilization and sensitivity of abdominal imaging techniques, identification of nonfunctional adrenal tumors has become more frequent. Adrenal lipoma should be included in the differential diagnosis of lipomatous adrenal tumors. (Endocr Pract. 2008; 14:209-212)  相似文献

Objective:In contrast to the high incidence of testicular adrenal rest tumors in adult male patients with congenital adrenal hyperplasia (CAH), ovarian adrenal rest tumors (OARTs) in female CAH patients are rare. In this case report, we describe a case of bilateral OART in a female patient with CAH due to 21-hydroxylase deficiency.Methods:We present a detailed case report with the clinical, imaging, and laboratory findings of the patient. The pertinent literature is also reviewed.Results:A 17-year-old patient was known to have CAH due to 21-hydroxylase deficiency. Since the second month of her gestational age, her mother was treated with cortisone-replacement therapy. The patient was treated with hydrocortisone and fludrocortisone since the neonatal period. Her pertinent history included a bilateral adrenalectomy at the age of 13 years in 2006, and for 3 years she led a normal puberty life with no complaint with hormonal replacement therapy. Nevertheless, in 2009, she developed a virilizing syndrome. Subsequently, she underwent surgery in December 2009 for right adnexectomy. However, the regression of the masculinizing mass was not complete and worsened several months after the surgery. A new pelvic magnetic resonance image showed the activation of a contralateral ovarian mass, necessitating a left adnexectomy in August 2010.Conclusion:This case demonstrates some interesting features of OART that pose challenges to its management. If an OART is detected early enough and glucocorticoid therapy is received, it is possible that the OART will decrease in size following suppression of adrenocorticotropic hormone levels.

ObjectiveTo discuss challenges in the diagnosis of adrenocortical carcinoma and to suggest surveillance measures after removal of selected adrenal nodules.MethodsWe present the case of a 65-year-old man with worsening hypertension and new-onset hypokalemia attributed to primary hyperaldosteronism due to a 3-cm right adrenal nodule.ResultsA laparoscopic right adrenalectomy was performed, and the histologic diagnosis was a benign adenoma. The patient’s hypertension and hypokalemia improved postoperatively but recurred 8 months later, and florid Cushing’s syndrome developed. Magnetic resonance imaging showed an 8-cm mass in the right adrenal bed and multiple hepatic metastatic lesions. Fine-needle biopsy confirmed the presence of adrenocortical carcinoma.ConclusionDespite a comprehensive biochemical, radiologic, and histologic assessment, the diagnosis of adrenocortical carcinoma can be missed. Particularly, we caution against undue reliance on the initial tumor size. We recommend that abdominal imaging be performed every 3 months for the first year and every 6 months for the second year after surgical removal of selected adrenal nodules.

ObjectiveTo describe the unique association of corticotropin-independent Cushing syndrome caused by cortisoland androgen-secreting black adrenal cortical adenomas with myelolipomatous change.MethodsWe report the clinical, laboratory, radiologic, and pathologic findings from 2 patients who presented with androgen excess and typical signs and symptoms of Cushing syndrome.ResultsEndocrine investigations showed high serum cortisol concentrations that lacked diurnal rhythm, undetectable plasma corticotropin concentrations, and absence of serum cortisol suppression after overnight dexamethasone suppression tests. Serum levels of adrenal androgens were elevated. Computed tomography of the abdomen revealed unilateral adrenal masses (largest lesional diameters 4.0 and 3.1 cm). On the basis of the plurihormonal hypersecretion and the imaging characteristics, adrenocortical carcinoma was considered as a possible diagnosis. However, histopathologic analysis in both patients revealed black adrenal cortical adenomas with myelolipomatous change. After surgery, adrenal androgens normalized, and the signs and symptoms of Cushing syndrome and androgen excess resolved. There was no evidence of recurrent disease at last follow-up.ConclusionsA unique form of corticotropin-independent Cushing syndrome is described: cortisoland androgen-secreting black adrenal cortical adenomas with myelolipomatous change. Although most patients with corticotropin-independent Cushing syndrome associated with androgen excess prove to have adrenocortical carcinoma, the clinician should be aware of the possibility of benign, black adrenal adenomas in this clinical setting.

ObjectiveTo report the case of a patient with a pheochromocytoma and apical left ventricular dysfunction that resolved after surgical resection of the pheochromocytoma, to review the effects of catecholamines on myocyte function and the concept that takotsubo cardiomyopathy (TC) is caused by excess catecholamines, and to illustrate the difficulty in the management of an acute coronary syndrome (ACS) during a hypertensive crisis attributable to a pheochromocytoma.MethodsWe present the clinical history, physical findings, laboratory results, and imaging studies in a 60-year-old man with an ACS, TC, and an incidentaloma later diagnosed to be a pheochromocytoma. The association with TC and the pertinent literature are reviewed.ResultsA 60-year-old man was suspected of having myocardial ischemia on the basis of symptoms of paroxysmal chest pain extending to the left shoulder, diaphoresis, ST-segment elevation on an electrocardiogram, and elevated serial levels of cardiac enzymes. Coronary angiography did not reveal substantial coronary artery obstruction but detected ballooning of the apical, anterior, and inferior cardiac walls, consistent with TC. He had a history of labile hypertension and palpitations of 3 months’ duration. An adrenal mass detected on a prior computed tomographic scan and increased 24-hour urine catecholamine levels were consistent with a pheochromocytoma. Treatment with phenoxybenzamine was initiated, and he underwent a right adrenalectomy, which confirmed that the tumor was a pheochromocytoma and dramatically improved the patient’s condition.ConclusionPheochromocytomas manifest with labile blood pressures and should be considered in the differential diagnosis of ACS. This case also supports the concept that TC is caused by excess catecholamines. (Endocr Pract. 2012;18:e77-e80)  相似文献

Objective: To investigate the outcome in patients with adrenal incidentaloma (AI).Methods: A retrospective evaluation of 637 patients with AI referred to a tertiary center over 8 years. Radiologic and hormonal evaluations were performed at baseline. Follow-up imaging was carried out if necessary, and hormonal evaluation was performed at 24 months according to national guidelines.Results: The mean age was 62.7 ± 11.6 years, and the mean AI size was 25.3 ± 17.0 mm at presentation. Hormonal evaluation revealed that 85.4% of all tumors were nonfunctioning adenomas, 4.1% subclinical Cushing syndrome (SCS), 1.4% pheochromocytoma, 1.4% primary hyperaldosteronism, 0.8% Cushing syndrome, 0.6% adrenocortical carcinoma, 0.3% congenital adrenal hyperplasia, 2.2% metastasis to adrenals, and 3.8% other lesions of benign origin. Bilateral tumors were found in 11%, and compared to unilateral tumors, SCS was more prevalent. Only 2 cases were reclassified during follow-up, both as SCS, but neither had had a dexamethasone suppression test performed at initial work-up. In patients diagnosed with an adrenal metastasis, 92.9% were deceased within 2 years. Excluding those with malignant tumors, 12.9% of patients died during the study period of up to 11 years due to other causes than adrenal.Conclusion: Most AIs were benign, but a small fraction of tumors were functional and malignant. The prognosis of patients with adrenal metastasis was extremely poor, but otherwise, the mortality rate was similar to that for the general population. Follow-up of AIs <4 cm with an initial nonfunctional profile and benign radiologic appearance appears unwarranted, but screening for congenital adrenal hyperplasia should be considered.Abbreviations: 17OHP = 17-hydroxyprogesterone ACC = adrenal cortical carcinoma ACTH = adrenocorticotropic hormone AI = adrenal incidentaloma CAH = congenital adrenal hyperplasia CT = computed tomography CS = Cushing syndrome DST = dexamethasone suppression test HPA = hypothalamic-pituitary-adrenal axis MRI = magnetic resonance imaging SCS = subclinical Cushing syndrome T2DM = type 2 diabetes mellitus UFC = urinary free cortisol  相似文献

ObjectiveTo report a case of hyperandrogenism attributable to the presence of an adrenal adenoma secreting dehydroepiandrosterone sulfate (DHEA-S) and an ovarian Sertoli-Leydig cell tumor secreting testosterone in a postmenopausal woman.MethodsThe laboratory, radiologic, and pathologic findings in our case are described. In addition, the pertinent literature is reviewed.ResultsA 56-year-old woman presented with a history of gradual increase in facial and body hair, scalp hair loss, male pattern baldness, and deepening of her voice, beginning a few years after spontaneous menopause at age 49 years. She had hypertension, obesity, and type 2 diabetes mellitus. Laboratory tests showed elevated levels of total testosterone (348 ng/dL) and DHEA-S (2,058 μg/dL), and a left adrenal tumor (3 by 4 cm) was detected on abdominal computed tomographic scan. Laparoscopic left adrenalectomy was performed, and the pathologic diagnosis was adrenal adenoma. The DHEA-S returned to normal levels, but the serum testosterone concentration remained elevated. Transvaginal ultrasonography disclosed an ovarian tumor. Bilateral oophorectomy was performed, and an ovarian Sertoli-Leydig cell tumor was diagnosed. The hormonal and clinical picture normalized after this surgical intervention.ConclusionAfter extensive review of the literature, we believe that this is the first reported case of a coincidental DHEA-S-secreting adrenal adenoma and a testosterone-secreting ovarian Leydig cell tumor causing signs of virilization.

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 report a case of PHACE syndrome— Posterior fossa brain abnormalities, Hemangioma (usually facial), Arterial anomalies, Coarctation of the aorta along with cardiac defects, and Eye abnormalities—in a 16-yearold female patient with a port-wine stain of the right periorbital area present since birth in conjunction with hypoplasia of the contralateral internal carotid artery.MethodsThyroid-stimulating hormone, free thyroxine, and growth hormone (GH) levels were measured, and insulin-induced hypoglycemia and arginine infusion tests were done. Radiologic investigations included sagittal enhanced T1-weighted magnetic resonance imaging of the brain and the pituitary gland as well as computed tomography and magnetic resonance angiography of the head and neck.ResultsThe patient had a normal karyotype. Her height and weight were below the 5th percentile for her chronologic age, and she had amenorrhea. Laboratory investigations revealed both thyroid and GH deficiencies and confirmed the diagnosis of hypogonadotropic hypogonadism. The imaging studies showed a right intraorbital hemangioma as well as an enhancing mass in the right internal auditory canal at the cerebellopontine angle, consistent with a posterior fossa hemangioma. Initiation of both thyroid and GH replacement therapy improved her growth rate and yielded a good clinical outcome.ConclusionIn patients with facial or neck hemangiomas, PHACE syndrome should be suspected, and brain imaging and cardiac, ophthalmologic, and endocrinologic evaluations are recommended to screen for other potential PHACE abnormalities.

ObjectiveTo report a rare case of Addison disease presenting with acute neurologic deterioration, and to dis- cuss previous reports and illustrative clinical lessons drawn from the case.MethodsWe detail the clinical presentation and se- quence of events leading to diagnosis of Addison disease in a 20-year-old man whose initial symptoms were those of acute neurologic deterioration.ResultsA 20-year-old man presented with acute, rapid neurologic deterioration. The patient required in- tubation, but his condition responded very well to man- nitol and dexamethasone. Head computed tomography showed a fourth ventricle reduced in size and basal cistern effacement, changes consistent with mild cerebral edema. Primary adrenal insufficiency was diagnosed after a low morning cortisol concentration prompted a corticotropin- stimulation test and serum aldosterone measurement (un- detectable). The diagnosis was almost missed because of suspected confounders of dexamethasone and etomidate use. Subsequently, the patient tested positive for anti-21- hydroxylase antibodies. Cerebral edema rarely occurs with Addison disease and is most likely secondary to hypon- atremia. Diagnosis in such cases may be complicated by resuscitative therapies; however, low cortisol levels should always be thoroughly investigated. This patient’s pres- entation was also unique in that he maintained a normal electrolyte profile despite hypoaldosteronism, a phenom- enon that may be explained by enhanced mineralocorticoid activity of exogenous cortisol.ConclusionsThe diagnosis of primary adrenal in- sufficiency may not be suspected in the absence of classic hyperpigmentation and hyperkalemia, but should remain in the differential diagnosis of acute confusion. While the use of dexamethasone and etomidate in initial resuscitation can transiently suppress adrenal function, any unusually low cortisol level merits thorough investigation.

ObjectiveTo report our experience using kinase in- hibition therapy with sorafenib in a patient with advanced adrenocortical carcinoma.MethodsWe describe the clinical,laboratory, and ra- diologic findings of the study patient and discuss the clini- cal course with sorafenib therapy.ResultsA 56-year-old woman presented with rapid development of virilization, cushingoid features, hyper- tension, weight gain, and abdominal distension. An 8-cm left adrenal lesion was found on computed tomography, re- moved surgically, and confirmed as adrenal carcinoma on pathologic examination. Postoperative scanning revealed metastases to both lungs and the liver that were confirmed by fine-needle biopsy, thus establishing stage IV disease. Treatment with the adrenolytic agent mitotane failed to halt disease progression. A trial of sorafenib resulted in regres- sion and eventual resolution of bilateral metastatic lung lesions, reduction in size of the hepatic lesion, normaliza- tion of androgen hypersecretion, and marked clinical im- provement. The radiologic and biochemical remission on sorafenib has continued for 28 months.ConclusionMultiple kinase inhibitors such as sorafenib provide targeted oncologic treatment and may be effective in treating advanced adrenal cancer.

ObjectiveTo report a rare case of multiple unilateral adrenal adenomas in which immunohistochemistry results confirmed primary hyperaldosteronism in each of 3 adenomas.MethodsWe present the clinical, laboratory, radiographic, and pathologic findings of a case of multiple unilateral adrenal adenomas.ResultsAlthough multiple nodules in both adrenal glands are fairly common in patients with bilateral hyperplasia, multiple unilateral nodules are extremely rare. A 45-year-old woman with a long-standing history of severe hypertension was found to have biochemical parameters consistent with primary hyperaldosteronism, multiple unilateral adrenal adenomas, and immunohistochemical test results confirming primary hyperaldosteronism arising from each of 3 adrenal nodules (measuring 2.2 × 2.2 cm, 1.7 × 0.7 cm, and 0.5 × 0.5 cm).ConclusionThis case illustrates the rare presentation of primary hyperaldosteronism as multiple unilateral adrenal adenomas in which immunohistochemistry results can confirm the suspected preoperative diagnosis as suggested by biochemical and radiographic evidence.

ObjectiveTo report an uncommon case of osteogenic sarcoma of the sella turcica after radiation treatment of a pituitary adenoma.MethodsWe present the clinical history, physical findings, laboratory data, imaging studies, and pathologic findings in a patient found to have osteogenic sarcoma of the sella after radiation therapy for a nonfunctioning pituitary adenoma.ResultsSix years after transsphenoidal resection and postoperative fractionated radiation therapy for a nonfunctioning pituitary adenoma that extended to the cavernous sinus, a 45-year-old man presented with a sinus infection, diplopia, and ophthalmoplegia of the right eye. A computed tomographic scan of the head showed a mass in the sella with involvement of the optic chiasm and right cavernous sinus. Transsphenoidal resection and debulking of the tumor revealed an osteogenic sarcoma. The patient was discharged from the hospital with residual diplopia and ophthalmoplegia. He was treated with levothyroxine, testosterone, and hydrocortisone. Six weeks later, the patient was readmitted after he was found unresponsive, and computed tomographic scans disclosed a massive cerebrovascular accident. He died a few days later.ConclusionOsteogenic sarcoma is a rare, late complication of radiation treatment of pituitary adenoma. Although radiotherapy remains an effective adjunctive treatment in patients with pituitary adenomas, particularly those with residual or recurrent tumor, potential complications must be acknowledged.
