[source] Ductal Eccrine Carcinoma Presenting as a Paget's Disease-Like Lesion of the BreastTHE BREAST JOURNAL, Issue 5 2001Byeong-Woo Park MD Some types of skin appendage tumors, particularly ductal eccrine carcinomas (DEC), imitate breast carcinomas histologically, thus causing great diagnostic challenges. We describe a case of DEC presenting as an eczematous, crusted skin lesion on the right nipple-areolar complex in a 67-year-old woman. A skin biopsy done under the clinical impression of Paget's disease of the nipple was initially misinterpreted as infiltrating ductal carcinoma, and a subsequent modified radical mastectomy revealed DEC exclusively confined to the nipple with perinodal tumor metastasis in one of the axillary lymph nodes. This case highlights the diagnostic difficulty caused by the histologic homology between breast carcinomas and skin appendage tumors with ductal differentiation.

Carcinoma en cuirasse is a form of metastatic cutaneous breast malignancy occurring most commonly on the chest as a recurrence of breast cancer, but it can be the primary presentation. Objective. To discuss the clinical features of carcinoma en cuirasse that distinguish it from hypertrophic scars and keloids of the chest. Method. We report a 63-year-old woman with primary cutaneous breast carcinoma presenting as keloid nodules on the chest that failed treatments for keloids. Biopsy revealed a pattern of breast carcinoma in the skin. Results. After further workup, no tumor was found in the deep breast tissue, but metastases were found in her axillary lymph nodes. Conclusions. Unusual keloid-like nodules or scars on the chest that fail to respond to therapy may be primary or metastatic malignancies, and adequate histologic verification should be obtained to avoid delay in the proper treatment. [source] Metastatic hepatocellular carcinoma presenting as a pancreatic mass by computed tomography scan and mimicking a primary neuroendocrine tumor: A potential pitfall in aspiration cytologyDIAGNOSTIC CYTOPATHOLOGY, Issue 12 2009Valerie A. Fitzhugh M.D. Abstract Hepatocellular carcinoma (HCC) is a highly malignant neoplasm, often presenting at late stage and portending a poor prognosis for the patient. The peripancreatic fat is a rare site of extrahepatic metastasis, and metastatic HCC can mimic primary pancreatic neoplasms, even in this location. It is crucial to be aware of this pitfall in the evaluation of aspiration cytology of pancreatic neoplasms and to develop a strategy to reach the correct diagnosis. We present an endoscopic ultrasound fine-needle aspiration diagnosis of metastatic HCC presenting as a pancreatic mass radiologically that had neuroendocrine features on various cytological and histological preparations. The metastatic lesions were located surgically in the peripancreatic adipose tissue with involvement of one peripancreatic lymph node. This case illustrates the utility of FNA for diagnosing uncommon presentations of HCC and the importance of clinical history, cell block, and an immunocytochemical panel in determining the origin of the tumor.

Schreiner M.D. Abstract Medullary thyroid carcinoma typically presents as dyscohesive plasmacytoid, spindled, or polygonal cells on fine-needle aspiration smears. We recently encountered a case of sporadic medullary thyroid carcinoma that presented as a hypercellular aspirate composed of cohesive aggregates of rectangle-shaped cells. The case was mistakenly reported as a hypercellular follicular neoplasm on cytology. Subsequent thyroidectomy revealed medullary carcinoma. We draw attention to this distinctive rectangular cell type as an additional morphology for medullary thyroid carcinoma. Diagn. Cytopathol. 2009. © 2009 Wiley-Liss, Inc. [source] High-grade neuroendocrine carcinoma presenting as an abscess: Diagnosis by fine needle aspiration and review of the literatureDIAGNOSTIC CYTOPATHOLOGY, Issue 9 2008Jonathon B. Herbst M.D. Abstract Neuroendocrine carcinomas (NEC) comprise about 2% of all carcinomas. Review of the literature indicates only a few cases of NEC presenting as an abscess, all having been diagnosed by tissue biopsy. Here, we report the FNA diagnosis of a high-grade neuroendocrine carcinoma presenting as an abscess of the axilla/chest wall in a 68-year-old man and review the pertinent literature. Diagn.

[source] Management of well-differentiated thyroid carcinoma presenting within a thyroglossal duct cystJOURNAL OF SURGICAL ONCOLOGY, Issue 3 2002Snehal G. Patel MD Abstract Background and Objective Well-differentiated thyroid carcinoma (WDTC) is diagnosed in approximately 1.5% of thyroglossal duct cysts (TGDC). No clear consensus exists regarding further management after adequate excision of the cyst, especially the role of total thyroidectomy and postoperative radioactive iodine therapy. The current review was undertaken in an attempt to clarify these issues. Methods Demographic, clinical, tumor, treatment, pathology, and outcome data on 57 eligible patients reported in recent literature were pooled together with 5 patients treated at our institution for this analysis. Results A Sistrunk operation was performed for resection of the thyroglossal duct cyst in the majority (90%) of patients. Histologic examination of the tumor in the cyst revealed that papillary carcinoma was the most frequent (92%) histologic type. A total thyroidectomy was performed consequent to the diagnosis of thyroglossal duct cyst carcinoma in approximately half of the 62 patients. A malignant tumor was reported in 27% of the thyroidectomy specimens. Postoperative radioactive iodine therapy was administered in 16 (26%) patients. With a median follow-up of 71 months (range 1,456 months), the 5- and 10-year Kaplan,Meier overall survival was 100 and 95.6%, respectively. There were no disease-related deaths reported in any of the patients. Univariate analysis revealed that the only significant predictor of overall survival was the extent of primary surgery for the thyroglossal cyst. The addition of total thyroidectomy to Sistrunk operation did not have a significant impact on outcome (P,=,0.1). Patients treated with postoperative radioactive iodine (RAI) fared significantly worse than those that did not need RAI, which may be explained by the fact that this modality would generally be used in patients with higher risk tumors. Conclusions The Sistrunk operation is adequate for most patients with incidentally diagnosed TGDC carcinoma in the presence of a clinically and radiologically normal thyroid gland. Results of adequate excision using the Sistrunk operation are excellent and the concept of risk-groups should be used to identify patients, who would benefit from more aggressive treatment. J. Surg.
