Sister Joseph's nodule in a liver transplant recipient: Case report and mini-review of literature

BACKGROUND: Umbilical metastasis is one of the main characteristic signs of extensive neoplastic disease and is universally referred to as Sister Mary Joseph's nodule. CASE PRESENTATION: A 59-years-old Caucasian female underwent liver transplant for end stage liver disease due to hepatitis C with whole graft from cadaveric donor in 2003. After transplantation the patient developed multiple subcutaneous nodules in the umbilical region and bilateral inguinal lymphadenopathy. The excision biopsy of the umbilical mass showed the features of a poorly differentiated papillary serous cystadenocarcinoma. Computed tomographic scan and transvaginal ultrasonography were unable to demonstrate any primary lesion. Chemotherapy was start and the dosage of the immunosuppressive drugs was reduced. To date the patient is doing well and liver function is normal. CONCLUSIONS: The umbilical metastasis can arise from many sites. In some cases, primary tumor may be not identified; nonetheless chemotherapy must be administrated based on patient's history, anatomical and histological findings.     

Fine Needle Aspiration of Sister Mary Joseph''s Nodule

A case of Sister Mary Joseph's nodule (umbilical metastasis) is described from a primary adenocarcinoma of the transverse colon. Needle aspiration cytology made the diagnosis which was confirmed by immunocytochemical localization of CEA, B72.3, EMA, and cytokeratin in the tumour cells. Extensive mucus production in the tumour cells was demonstrated by alcian blue and mucicarmine stains.     

Umbilical metastases: current viewpoint

BACKGROUND: Umbilical metastases from a malignant neoplasm, also termed Sister Mary Joseph's nodule, are not commonly reported in the English literature, and they have usually been considered as a sign of a poor prognosis for the patient. The present article reports on the current view point on umbilical metastasis besides discussing the epidemiology, clinical presentation, pathophysiology and treatment. METHOD: A search of Pubmed was carried out using the term 'umblic*' and 'metastases' or metastasis' revealed no references. Another search was made using the term "Sister Joseph's nodule" or sister Joseph nodule" that revealed 99 references. Of these there were 14 review articles, however when the search was limited to English language it yielded only 20 articles. Articles selected from these form the basis of this report along with cross references. RESULTS: The primary lesions usually arise from gastrointestinal or genitourinary tract malignancies and may be the presenting symptom or sign of a primary tumour in an unknown site. CONCLUSION: A careful evaluation of all umbilical lesions, including an early biopsy if appropriate, is recommended. Recent studies suggest an aggressive surgical approach combined with chemotherapy for such patients may improve survival.     

Parathyroid carcinoma with occult bone metastases diagnosed by fine needle aspiration cytology

A case with persistent hypercalcemia following complete resection of a primary parathyroid carcinoma is presented. An occult bone metastasis was diagnosed by fine needle aspiration (FNA) cytology of a lytic bone lesion clinically presumed to be a "brown tumor" of hyperparathyroidism. The cytologic features of the metastatic lesion were similar to those of the resected primary lesion and of a previously identified metastasis. The potential usefulness of FNA cytology in this clinical setting is discussed.     

Carcinoid tumor metastatic to breast diagnosed by fine needle aspiration. Case report and literature review

Fine needle aspiration (FNA) biopsy was used to study a mass in the left breast in a patient with a previous history of an ileal carcinoid tumor and later lymph node metastases who presented with bilateral palpable breast masses. The FNA specimens showed the lesion to be a carcinoid tumor. The metastatic nature of the lesion was proven by positive restaining of FNA smears by both the Sevier-Munger technique (demonstrating abundant argyrophilic cytoplasmic granules) and the Fontana-Masson method (showing argentaffin cytoplasmic granules). The distinction between primary and metastatic carcinoid tumors of the breast is discussed, as is their origin and their differentiation from other malignancies of the breast.     

Metastatic tumors in fine needle aspiration biopsy of the thyroid

A series of almost 25,000 thyroids examined by fine needle aspiration (FNA) biopsy was reviewed to ascertain the incidence and presentation of metastatic cancers in thyroid FNA samples. Metastatic cancers in FNA samples from the thyroid were identified in 25 cases (0.1%); the primary tumors were carcinomas of the kidney (8 cases), lung (7 cases), breast (5 cases), cervix uteri (1 case) and colon (1 case) and 1 case each of malignant melanoma, malignant pleural mesothelioma and rhabdomyosarcoma. FNA cytology was positive in all 25 cases. In 11 cases, the primary tumor was clinically known at the time of FNA biopsy; of the other 14 cases, cytology suggested that the malignancy was metastatic in only 5. Metastases of renal and mammary adenocarcinomas were almost indistinguishable from follicular and papillary thyroid carcinomas on cytologic grounds. The results demonstrate the rarity of this finding and the difficulty of diagnosing a metastatic tumor in the thyroid by FNA biopsy, in the absence of a clinical history of a prior primary neoplasm.     

Fine needle aspiration in a malignant lymphoepithelial lesion: a case report

BACKGROUND: A primary malignant lymphoepithelial lesion (MLEL) of the salivary gland is a rare tumor. Though histologic morphology of this lesion is well documented, the cytologic findings regarding fine needle aspiration (FNA) are not yet well described. CASE: A 56-year-old Thai woman from Udonthanee was admitted to Srinagarind Hospital with a 2-year history of a painless mass in the left parotid gland. FNA of the left parotid mass was performed, and findings suggestive of malignancy were discovered. A wide local excision was performed 1 year later, and MLEL with metastasis to the regional lymph nodes was diagnosed by histopathology. CONCLUSION: We report our first experience of cytologic findings from FNA of histologically diagnosed MLEL. The aspirate comprised groups of cohesive and isolated malignant epithelials with a background of numerous lymphocytes. Cytotechnologists should be reminded of this rare lesion when confronted with a lymphocytic background from either benign or malignant lesions.     

Fine needle aspiration of metastatic and hematologic malignancies clinically mimicking pancreatic carcinoma.

The fine needle aspiration (FNA) cytology findings in 19 cases of hematopoietic and metastatic neoplasms that radiographically mimicked primary pancreatic carcinoma are reported. These cases represented 11% of 176 malignant diagnoses in a series of 304 pancreatic FNAs. The cytologic diagnoses included 7 non-Hodgkin's lymphomas, 2 Hodgkin's lymphomas, 6 small cell carcinomas (4 lung, 1 gallbladder, 1 skin), 3 squamous cell carcinomas (2 cervix, 1 esophagus) and 1 hepatocellular carcinoma. In six cases the pancreatic lesion was the initial presentation of malignant disease. These included five lymphomas, which probably involved peripancreatic lymph nodes, and a metastatic small cell carcinoma of pulmonary origin. Recognition of unusual morphologic features of pancreatic carcinoma raised the possibility of extrapancreatic malignancies. Electron microscopy and immunocytochemistry performed on FNA specimens were helpful in selected cases. The FNA diagnosis of hematopoietic and metastatic neoplasms that clinically mimic pancreatic carcinoma prompts appropriate clinical studies and treatment and eliminates the need for open pancreatic biopsy and/or resection.     

Fine needle aspiration cytology of neoplasms metastatic to the breast

The fine needle aspiration (FNA) cytologic findings in 18 cases of metastatic neoplasms of the breast are reported. The cases were encountered in a combined series of 2,529 FNA breast biopsies, of which 666 were malignant; the metastatic neoplasms of the breast thus constituted 2.7% of all the malignant breast tumors. The series consists of 15 women and 3 men, with a mean age of 48 years (range of 11 to 73 years). Sixteen biopsies confirmed metastatic malignancy in patients with known extramammary primaries; the prebiopsy clinical diagnoses in six of the patients were benign breast lesions. In eight patients, the clinical differential diagnosis was either a benign or malignant primary breast lesion versus a metastatic malignancy. In two additional patients, the FNA biopsy identified metastatic neoplasms from unsuspected extramammary primaries. The metastatic neoplasms included three small-cell carcinomas of the lung, one squamous-cell carcinoma of the lung, two malignant melanomas, three ovarian malignancies, including a dysgerminoma, and one each of carcinoma of the fallopian tube, endometrial carcinoma, transitional-cell carcinoma of the urinary bladder, prostatic carcinoma, acute granulocytic leukemia, lymphoma, mycosis fungoides, hepatoma and neuroblastoma of the retroperitoneum. Recognition of unusual cytologic patterns raised the suspicion of, or confirmed the diagnosis of, malignancy in all cases, with no false-negative diagnoses. None of the cases were cytologically interpreted as a primary breast malignancy. Ancillary studies performed on the FNA material, including immunocytochemistry, contributed to a definitive diagnosis in three cases. FNA diagnosis of metastatic malignancy of the breast is essential in order to avoid unnecessary mastectomy and to ensure appropriate chemotherapy and/or irradiation treatment.     

Fine needle aspiration biopsy in the diagnosis of intrathoracic masses.

During a 3.5-year period (January 1, 1987, to June 30, 1990) 420 percutaneous fine needle aspiration (FNA) biopsies were performed on 390 patients (309 males, 81 females) suffering from one or more intrathoracic, radiologically visible lesions. Aspirations were carried out using 21- or 23-gauge Chiba needles under fluoroscopic or computed tomographic control. The aspirates were used to make minibiopsies and cytologic smears. Diagnosis was possible in 373 cases (95.64%): on the first pass in 344 cases, on the second in 28 cases and on the third in 1. In 17 cases (4.36%) the aspirate was inadequate for diagnosis. There were complications in 10 cases (2.56%) (9 pneumothorax and 1 hemophtysis) requiring intensive care. The 373 percutaneous FNA biopsy diagnoses included 256 malignant tumors (68.63%), of which 234 were primary and 22 were secondary, and 117 benign lesions (31.37%), 5 of them neoplastic and 112 nonneoplastic. Three hundred two of 373 percutaneous FNA biopsy diagnoses were followed (80.96%). One hundred twenty-three follow-ups were histologic (40.73%), including secondary tumors, which could be compared with the primary histotype. Twenty-eight follow-ups were cytologic (9.27%), and 151 were clinical (50.00%), using progression of the disease or the beginning of chemoradiotherapy as a criterion for malignancy and a stable condition or regression of the lesion with nononcologic medical treatment as a criterion for benignity. Percutaneous FNA biopsy diagnoses were confirmed in 288 cases (221 true positives and 67 true negatives) and unconfirmed in 14 (1 false positive and 13 false negatives). Specificity, sensitivity, negative predictive value, positive predictive value and total diagnostic accuracy were, respectively, 98.52, 94.44, 83.75, 99.54 and 95.36%. The histologic typing accuracy of percutaneous FNA biopsy on 70 specimens of surgically removed malignant epithelial neoplasias was 70.00%. These results confirm that percutaneous FNA biopsy is a reliable method of diagnosing intrathoracic masses and reduces the need for diagnostic thoracotomy.     

Coccidioidomycosis osteomyelitis masquerading as a bone tumor. A report of 2 cases

BACKGROUND: Coccidioidomycosis involving the lung is common in endemic areas. However, it is unusual for it to present as a solitary bone lesion. CASES: Two cases of Coccidioides immitis osteomyelitis clinically and radiographically mimicked a primary bone tumor. Fine needle aspiration (FNA) biopsy of these lytic bone lesions yielded diagnostic material. Aspirated material in 1 case showed a suppurative, granulomatous inflammation and scattered spherules with refractile walls, some containing endospores consistent with coccidioidomycosis. Smears in the other case showed acute inflammation and necrosis, and rare spherules were identified with the Gomori-mathenamine-silver stain. C immitis infection was confirmed by culture in both cases. CONCLUSION: Although rare, coccidioidomycosis can involve the bone and mimic a primary bone tumor. FNA biopsy is helpful in differentiating between inflammatory and neoplastic processes involving bone by acquiring material for cytologic studies and cultures.     

Posters. P19 Cervical carcinoma with metastases to the tympanic membrane: an unusual presentation

Introduction Fine needle aspiration (FNA) is a well‐established diagnostic technique which is frequently used to diagnose head and neck neoplasms. Clinical decisions concerning treatment of malignant salivary gland tumours, the extent of surgery and advisability of pre‐operative irradiation can be helped by prior knowledge of tumour type. Aim The aim of this study was to do an audit of all salivary gland FNAs carried out in Beaumont Hospital over a 14‐year period. Methods All salivary gland FNAs between 1989 and 2002 were reviewed. Where available, the corresponding follow‐up histological specimens were studied. Results During this 14‐year period, 305 patients with salivary gland lesions had FNA of the lesion performed. The total number of aspirates performed was 343. Of these, 184 had histologies available for follow‐up. Eighty‐nine aspirates were reported as inadequate; 89 as inflammatory, normal or consistent with cyst contents. One hundred and thirteen aspirates were diagnosed as a benign entity. Thirty‐three aspirates were reported as malignant (21 of which were felt to be primary to the salivary gland and 12 metastatic). Sixteen cases were called suspicious. Good correlation between FNA findings and histology was seen in the majority of cases (145 of 183). Some diagnostic problem areas were identified. These included the following: lymphomas (seven called benign on FNA), Warthin's tumour (seven not diagnosed or misdiagnosed on FNA) and mucoepidermoid carcinoma (one reported as pleomorhic adenoma and one as benign/cystic on FNA). Seven pleomorphic adenomas were not diagnosed on FNA pre‐operatively, predominantly due to inadequacy of the specimen. Three other malignancies (acinic cell carcinoma, lymphoepithelial carcinoma and carcinoma ex‐pleomorphic adenoma), while not diagnosed on FNA, were called suspicious, with re‐biopsy advised. Conclusion FNA cytology of salivary glands is an accurate method for evaluation of both benign and malignant lesions, enabling optimum surgical and adjuvant therapy decision‐making pre‐operatively. Well‐defined problem areas are identified and, therefore, clinicopathological correlation is required in these cases.     

Hepatic actinomycosis diagnosed by fine needle aspiration. A case report

A 43-year-old woman, a long-term intrauterine contraceptive device (IUD) wearer with a history of Actinomyces organisms seen in cervicovaginal smears, developed hepatic actinomycosis 13 months after removal of the IUD. The liver involvement was diagnosed by fine needle aspiration (FNA) cytology and the use of immunocytochemical techniques. Histopathologic examination of a right pelvic mass removed at surgical exploration revealed an Actinomyces tuboovarian abscess, the primary lesion in this case. The importance of cytologic detection of Actinomyces in cervicovaginal smears for the prevention of IUD-related pelvic inflammatory disease (PID) is discussed, as is the usefulness of FNA cytology in the diagnosis of systemic actinomycosis.     

Focal adenomatoid hyperplasia of salivary glands. A differential diagnostic problem in fine needle aspiration biopsy

Adenomatoid hyperplasia of minor salivary glands is an idiopathic lesion usually involving the palate and mimicking a primary salivary gland neoplasm. In particular, the lesions may resemble low-grade mucoepidermoid tumors clinically and by fine needle aspiration (FNA) cytology. An illustrative case is presented, and the nature of this unusual entity is reviewed. Its importance in the differential diagnosis of FNA biopsies of minor salivary gland lesions is also discussed.

Fine needle aspiration (FNA) cytology of Rosai Dorfman disease
Rosai Dorfman disease (sinus histiocytosis with massive lymphadenopathy (SHML)) is a benign self-limiting disorder that commonly involves the lymph nodes. We reviewed eight cases of this entity aiming to document the cytomorphological features. Of the eight cases, a preoperative diagnosis was suggested in seven cases. Pertinent features included: numerous large histiocytes with prominent emperipolesis (documented by a halo around the cell), fine vacuoles in the cytoplasm and lymphocytes and plasma cells in the background. In some cases the histiocytes showed atypia. In one biopsy-proven case a diagnosis of Hodgkin's was suggested, emphasizing the pitfalls associated with the FNA diagnosis of this lesion.     

Frequency and rationale of fine needle aspiration biopsy conversion to core biopsy as a result of onsite evaluation

OBJECTIVE: To measure the frequency and analyze the rationale and potential diagnostic benefits of converting the fine needle aspiration (FNA) procedure to core biopsy. STUDY DESIGN: The frequency of conversion to core biopsy was calculated over 13 months. Analysis of these cases was conducted in regard to the appropriateness for conversion and whether the core biopsy provided additional specific diagnostic information. RESULTS: During this period, the onsite triaging pathologist recommended FNA conversion to core biopsy in 31 of 821 procedures (3.7%). In 3 instances, the core biopsy could not be performed. The rationale for conversion in the remaining 28 cases (3.4%) included either scant aspirated material in 9 cases (32%) or an anticipated need for additional histologic material to further characterize the lesion in the other 19 (68%). In 27 cases (96%), the rationale for conversion was considered to be appropriate, and in 3 of these (11%) the core provided a change in diagnosis. Additional useful diagnostic information was identified in 12 cases (44%). CONCLUSION: Conversion to core biopsy during FNA is infrequent but justified in most cases. Appropriate utilization of this approach is helpful and may be cost effective.     

Implementation of a joint protocol for the management of thyroid nodules with a cytological diagnosis of follicular lesion of undetermined significance: experience in one hospital

Background: Follicular lesion of undetermined significance (FLUS) was introduced for fine needle aspiration (FNA) cytology in which there is insufficient evidence to classify the lesion as follicular neoplasm/suspicious of follicular neoplasm or suspicious for malignancy. The recommended management was repeat FNA and correlation with clinical and radiological data. In 2009 we started a joint clinicopathological protocol to improve management of FLUS, recommending follow‐up with repeat FNA at 6 months. The aim of this study was to report on the audit of results of this protocol. Methods: We reviewed the medical records of the patients with FLUS at a single hospital. Between 2007 and 2010 we found 135 cases with this diagnosis (3.6%). We only had long enough follow‐up information for the 95 patients that were included in the present study. Results: FLUS was diagnosed in 74 FNAs before protocol implementation (3.2%) and 61 FNAs after (4.2%), with follow‐up of 46 and 49 patients, respectively. Before 2009, 38/46 (82.6%) patients had surgical excisions, compared with 32/49 (65.3%): a significant reduction of 17% in the number requiring surgery (P = 0.05). We have also shown a reduction in the median time to surgery (11.9 versus 2.9 months). Despite the joint protocol, the FNA was only repeated in two patients. The histological diagnoses were similar in the two periods of time: 31.6% and 31.3% follicular adenomas; 13.1% and 3.1% (P = 0.2) papillary carcinoma (follicular variant). Conclusions: Implementation of a joint protocol reduced the number of surgical operations in patients with FLUS but in most cases FNA was not repeated as recommended. Excision was justified in one‐third of operated patients. Less than 15% of lesions were malignant, which is in accordance with previous reports in the literature.     

Cryptococcal osteomyelitis. Report of a case with aspiration biopsy of a humeral lesion with radiologic features of malignancy

BACKGROUND: Osteomyelitis due to Cryptococcus neoformans typically exhibits lytic lesions on radiographs. Extensive periosteal reaction is an uncommon feature. CASE: A 68-year-old man presented with pain and swelling in the left elbow. Radiologic studies exhibited a lytic humeral lesion with extensive periosteal reaction, interpreted as a malignant neoplasm. Fine needle aspiration biopsy (FNA) revealed abundant cryptococcal organisms. CONCLUSION: Cryptococcus is an uncommon cause of lytic osseous lesions that may mimic malignant neoplasms. Extensive periosteal reaction may support a radiologic diagnosis of primary osseous malignancy in rare cases. FNA with examination of Diff-Quik-stained slides may be employed for distinguishing cryptococcal osteomyelitis from malignant tumors and for prompt identification of the organisms.     

Papillary-cystic variant of acinic cell carcinoma of the salivary gland diagnosed by fine needle aspiration biopsy. A case report

BACKGROUND: Fine needle aspiration (FNA) biopsy is reliably used to classify most conditions involving the salivary glands. It is useful for establishing, or at least suggesting, the diagnosis in unusual cases or narrowing the differential diagnosis. CASE: A 25-year-old male presented with a slowly enlarging mass of the left parotid. FNA biopsy of the parotid gland was performed, and a diagnosis of papillary-cystic variant of acinic cell carcinoma was suggested. The patient underwent incomplete resection of the lesion, which was interpreted as acinic cell carcinoma. CONCLUSION: Papillary-cystic variant of acinic cell carcinoma is rarely seen, especially in young people. FNA biopsy is a useful diagnostic procedure that can help diagnose this relatively uncommon type of salivary gland neoplasm and guide its management.     

Fine needle aspiration cytology of eyelid tumors

Fine needle aspiration (FNA) biopsy was performed on 19 patients with eyelid masses. Six of the patients also had preauricular/submandibular nodal enlargements aspirated. Histopathologic study was performed in ten of the cases. FNA cytology made the diagnosis of an epithelial malignancy in 17 cases (10 sebaceous carcinomas, 4 poorly differentiated carcinomas, 2 squamous cell carcinomas and 1 malignant melanoma). The diagnostic accuracy of FNA cytology in evaluating eyelid masses was thus 89.4%; there were two false-negative cases. All nodal FNA smears revealed metastases of the respective primary tumors. This study indicated that FNA cytology is a simple and efficient method for making the diagnosis of malignancy in eyelid masses, especially in those patients who are not suitable candidates for surgery. Subsequent nodal metastases and tumor recurrence were detected without difficulty using FNA smears.
