The Screening and Electron Microscopy Observation of Mammary Analogue Secretory Carcinoma in Chinese

Mammary analogue secretory carcinoma of salivary gland (MASC) is a tumor with histopathologic and immunophenotypic features mimicking secretory carcinoma of the breast harboring the ETV6 split. The expression of mammaglobin, S-100, Ki-67, P63 and ETV6 split were detected in twelve cases of acinar cell carcinoma and fourteen cases of mammary analogue secretory carcinoma of salivary gland by immunohistochemistry and fluorescence in situ hybridization respectively. The expression of ETV6 gene split was detected in fourteen mammary analogue secretory carcinomas of salivary gland with positive expression of mammaglobin.
