Mammary analogue secretory carcinoma (MASC) is a rare salivary gland tumor analogous to secretory carcinoma of the breast. The diagnosis of MASC can be challenging due to substantial morphologic and immunohistochemical similarities with other salivary gland tumors. The differential diagnosis of MASC is broad and includes intraductal carcinoma, acinic cell carcinoma, and adenocarcinoma, not otherwise specified. Although molecular testing for ETV6 gene rearrangement is characteristic of MASC and has not been shown in any other salivary gland tumor, a particular challenge arises when such testing is unavailable, or when molecular testing for ETV6 gene rearrangement is negative in a suspected case of MASC. Our study presents the diagnostic workup of a challenging case of MASC with immunohistochemistry, electron microscopy, and cytogenetic studies performed to resolve the diagnosis.

<p>Mammary analogue secretary carcinoma are salivary gland tumors similar to secretary carcinoma of breast histologically. It usually affects adults with mean age group of 45 years. Clinically it is usually slow growing, low grade malignancy with favorable prognosis. We are reporting a case of 47 years old female presented with complaints of swelling behind left ear for last 7 years. It was slow growing, painless and persistent. On examination, 4 x 3 cm swelling was present just below left ear lobule. It was nontender, firm, irregular in shape with smooth surface with slight mobility and overlying skin pinchable. Fine needle aspiration cytology suggested benign tumor with cystic change. On contrast enhanced computed tomography scan, there was a lobulated hypodense lesion measuring 24×35×32 mm with internal septations and enhancement of wall in expected location of superficial as well as deep lobe of left parotid gland. Patient underwent left total conservative parotidectomy and histopathology came out to be secretory analogue mammary carcinoma. Subsequently she received post-operative radiotherapy. Patient is on regular follow up and disease free till date. Usually mammary analogue secretory carcinoma is a low-grade malignancy with good prognosis. Immunohistochemistry is confirmatory which shows positivity for S-100 protein and mammaglobin.</p>

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

Malignant Salivary Gland Tumors

Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor, with a limited number of published reports. Less than three hundred cases have been reported in the literature and only 18 of these cases have been reported in minor palatal salivary glands, though publication bias is likely a factor. We present a case of a 57-year-old male who was diagnosed with MASC tumor presenting in a minor salivary gland and briefly review the current literature. MASC has a variety of histological features and different range of clinical behaviors. The histopathological diagnosis of MASC can be difficult, and the immunohistochemical profile of MASC is still being updated. The gold standard for MASC diagnosis is cytogenetics, with the majority having a translocation t(12;15)(p133;q25). Presently, there is no conclusive evidence that MASC should be treated differently than any other low-grade malignant salivary gland tumors, though high-grade transformation has been described.

Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that shares the same histologic appearance and ETV6 gene (12p13) rearrangement as secretory carcinoma of the breast. Prior to its recognition, MASC cases were commonly labeled acinic cell carcinoma and adenocarcinoma, not otherwise specified. Despite distinctive histologic features, MASC may be difficult to distinguish from other salivary gland tumors, in particular zymogen-poor acinic cell carcinoma and low-grade salivary duct carcinoma. Although characteristic morphologic and immunohistochemical features form the basis of a diagnosis of MASC, the presence of an ETV6-NTRK3 gene fusion is confirmatory. Given its recent recognition the true prognostic import of MASC is not yet clearly defined.
