<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>

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.

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.

Secretory carcinoma (SC) is a recently described salivary gland tumor reported in the fourth edition of World Health Organization classification of head and neck tumors. SC is characterized by strong S-100 protein, mammaglobin, and vimentin immunoexpression, and harbors a t(12;15)(p13;q25) translocation which leads to ETV6-NTRK3 fusion product. Histologically, SC displays a lobulated growth pattern and is often composed of microcystic, tubular, and solid structures with abundant eosinophilic homogenous or bubbly secretion. SC is generally recognized as low-grade malignancy with low-grade histopathologic features, and metastasis is relatively uncommon. In this case, we described a SC of hard palate that underwent high grade transformation and metastasis to the cervical lymph node in a 54-year-old patient. In addition, this case showed different histological findings between primary lesion and metastasis lesion. Therefore, the diagnosis was confirmed by the presence of ETV6 translocation. Here, we report a case that occurred SC with high-grade transformation in the palate, and a review of the relevant literature is also presented.

Background: Mammary analogue secretory carcinoma (MASC) of the salivary gland shows morphologic similarities and shares an immunophenotype and characteristic ETV6-NTRK3 translocation with secretory carcinoma of the breast. We present a buccal case of MASC along with a survey-based debate about its cytologic diagnosis by fine-needle aspiration (FNA). Case: FNA of the buccal nodule of a 58-year-old Japanese man was initially performed by 3 cytologists who gave different assessments of the Papanicolaou classification (i.e., class II, III, and V). To investigate the potential for discrepant diagnosis of MASC on a larger scale, we distributed a survey with questions about the cytological diagnosis of the present case to cytologists at other institutions. A total of 109 cytologists completed the survey, providing varying assessments of the Papanicolaou classification: class I/II (14%), class III (53%), and class IV/V (33%). Most of the respondents (72%) could not identify a particular tumor or disease. Even the respondents who identified a particular tumor suggested widely differing diagnoses, from a benign lesion to various malignant tumors. Only 2 respondents correctly identified MASC. Conclusion: Our experience and the results of the survey suggest difficulty in the cytodiagnosis of MASC.

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.
