Median raphe cyst (MRC) is an uncommon, asymptomatic benign lesion, that may present anywhere on the midline ridge between the external urethral meatus and the anus. Although they are developmental in origin, they often present in the postpubertal age, aggravated by trauma, and are frequently infected secondarily. MRCs are often misdiagnosed as epidermal cysts, steatocystoma multiplex, and eccrine cystadenomas. They are underrecognized and less than ten case reports exist from the Indian subcontinent. We, herein report a male with an immunohistochemically proven parameatal MRC.
正中缝囊肿（MRC）是一种罕见的无症状良性病变，可出现在尿道外口与肛门之间中线嵴的任何部位。尽管它们起源于发育异常，但通常在青春期后出现，因创伤而加重，且常继发感染。MRC常被误诊为表皮囊肿、多发性皮脂囊肿和小汗腺囊腺瘤。它们未得到充分认识，印度次大陆的病例报告不足十例。在此，我们报告一例经免疫组织化学证实的尿道口旁MRC男性患者。
