Deskripsi
Mammary analogue secretory carcinoma (MASC) of the salivary gland is a malignant tumor which bears morphologic, immunohistochemical and molecular features similar to those of mammary secretory carcinoma. The tumor is considered as a low-grade malignancy perhaps slightly more aggressive than acinic cell carcinoma. High-grade transformation with recurrences, regional nodal involvement, metastases, and cancer-related death has been reported in a few cases. We report an unusual case of large MASC of the parotid gland in a young patient without regional lymph node involvement. To the best of our knowledge till date such a large MASC of the salivary gland has not been reported in the English literature.
