Abstract:
Mammary analog secretory carcinoma (MASC) of the parotid gland is a rare and recently described lesion. We report the case of a 46-year-old man with a tumor of the parotid gland which was carried to the diagnosis of MASC. Diagnostic was confirmed by highlighting the ETV6-NTRK3 gene translocation. However, some morphologic and immunohistochemical features are suggestive of this entity. This carcinoma should be distinguished from its main differential diagnoses: acinic cell carcinoma and low grade cribriform cystadenocarcinoma.

The Mammary Glands
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
