Mammary analogue secretory carcinoma is a rare salivary gland tumor that has a wide range of clinical presentation ranging from indolent, local and slowly growing tumors to a very aggressive, infiltrative and widely metastasizing forms. We report a case of an unfortunate patient whose tumor had a very quick ominous disease course with aggressive clinical and histological presentation. This case is the first case, to our knowledge, to be reported in the literature from Saudi Arabia of MASC with features of high grade transformation
A recent described entity, mammary analogue secretary carcinoma (MASC) in 2010 by Skalova et al whose morphological and immunohistochemical features are similar in secretory carcinoma of the breast and salivary gland. This is a low-grade carcinoma which presents as a firm, slow-growing, circumscribed lesion with male preponderance. We present a case report of MASC.
