Abstract:  Mammary analogue secretory carcinoma (MASC) is a primary low-grade salivary gland tumor that has been first reported in 2010, also called as secretory carcinoma of the parotid gland. It has the same histological, immunophenotypic, and molecular characteristics as secretory breast cancer (SBC), and is often misdiagnosed as acinar cell carcinoma (AciCC) of the salivary gland. Due to the small number of patients with secretory carcinoma of the parotid gland, the guiding principles of diagnosis, treatment, and follow-up have not been standardized. Through report of a young male patient with primary secretory carcinoma of the parotid gland admitted to Jining First People's Hospital in May 2016, we aim to improve the understanding on this diagnosis and provide evidences for making standardized treatment options.

摘要： 类似乳腺分泌性癌（mammary analogue secretory carcinoma，MASC）是2010年首次报道的一种原发性涎腺低级别肿瘤，也称腮腺分泌性癌（secretory carcinoma，SC）。其组织学、免疫表型和分子生物学特征与乳腺分泌性癌（secretory breast cancer，SBC）相同，常被误诊为涎腺腺泡细胞癌（acinar cell carcinoma，AciCC）。由于腮腺SC患者数量较少，其诊断、治疗和随诊的指导原则尚未标准化。我们通过报道济宁市第一人民医院2016年5月收治的1例青年男性原发性腮腺SC患者，旨在提高对这一诊断的认识，为制定标准的治疗方案提供依据。
