Secretory carcinoma is a rare low-grade breast carcinoma, initially termed "juvenile breast cancer," but it is now known to occur in adults of both sexes. It is the only epithelial tumor of the breast with a balanced translocation, t(12;15), that creates an ETV6-NTRK3 gene translocation. In this paper, a 19-year-old male patient has had a right breast mass for 9 years which suddenly increased in size with no evidence of palpable axillary lymph nodes. The mass was excised for frozen section and was diagnosed as malignant growth for simple mastectomy. Microscopic examination revealed the classical features of secretory carcinoma. The tumor cells were positive for EMA and S-100 protein and focally positive for cytokeratin and ER but negative for progesterone receptor, CD34, and CEA. Four months later the patient developed ipsilateral axillary lymph node enlargement, with lymph node metastases in five of the dissected 19 lymph nodes. The patient was treated with six courses of chemotherapy and radiotherapy. Conclusion. Though considered an indolent neoplasm, secretory carcinoma does metastasize to lymph nodes. Surgery in the form of mastectomy with axillary clearance is the treatment of choice. This paper includes a rare case report of secretory carcinoma in young male patient, with axillary lymph node metastasis in spite of the indolent nature that this tumor is known to display.

Mammary analog secretory carcinoma (MASC) of salivary gland is a recently described neoplasm that morphologically and immunohistochemically resembles secretory carcinoma of the breast. Genetically, both of them harbor ETV-6-NTRK-3 fusion rearrangement. One case of primary MASCs arising from the eyelid is reported. The patient was a 52-year-old man. Microscopically, the tumor exhibited nodular aggregation of solid, tubular, and microcystic/macrocystic structures. Characteristic "colloid-like" eosinophilic secretory material was present within intraluminal spaces. Immunohistochemically, the tumor cells were positive for mammaglobin, S-100, STAT5a, vimentin, GCDFP-15, AE1/AE3, EMA, and CK7 and were negative for DOG-1, CK5/6, and SMA. A dual color break-apart fluorescence in situ hybridization probe identified rearrangement of the ETV6 gene locus on chromosome 12. The patient had no history of breast or salivary gland tumor. The tumor was completely excised, and the patient has no evidence of recurrent disease or metastasis after 1-year follow-up. A diagnosis of primary MASC was rendered. MASC has never been reported occurring in ocular region. This type of secretory carcinoma probably originates from sweat glands or accessory lacrimal glands, Wolfring and Krause. This unique case expands the clinicopathologic landscape of MASCs for better characterization of this rare entity.
