Mammary Analogue Secretory Carcinoma Of The Parotid: An Arduous Maze To Solve

Mammary analogue secretory carcinoma (MASC) is an unusual and rare salivary gland malignancy that recapitulates the genetic microscopic features of breast (SCB) which equally entity. MASC SCB express S-100 protein, vimentin, mammaglobin, harbor a t (12; 15) (p13; q25) translocation leads to ETV6-NTRK3 fusion product. The morphology not specific can overlap with many tumors. S100 mammaglobin’s strong positivity confirm diagnosis MASC. along immunohistochemical findings provides important clues for diagnosis. Recent advances in molecular pathology help investigating both differential prognosis oncology. Molecular testing recommended arrive at We report case parotid 47-year-old male patient his profile.t.
