title: Isolated Metastasis in Male Breast from Differentiated Thyroid Carcinoma - Oncological Curiosity. A Case Report and Review of Literature.
abstract: Papillary carcinomas are the most common thyroid malignancy accounting for approximately 80 % of thyroid cancers (Rosenbaum and McHenry Expert Rev Anticancer Ther 9:317-329, 2009). They generally manifest as solitary nodules in the thyroid with or without cervical lymphadenopathy. Distant metastases though rare, are commonly seen in lungs and bones, other rare sites are parotid, skin, brain, ovary, adrenal, kidney, Pancreas and breast. We herein present an unusual case of breast lump as an initial presentation of a well differentiated thyroid cancer in a male patient. Our case is unique since it presented with isolated breast metastasis in a male patient in the absence of primary diagnosis. This prompted us to report the case with review of literature. A brief review of literature follows.
