Median raphe cyst is a very rare, benign congenital lesion occurring mainly on the ventral aspect of the penis, but can develop anywhere in the midline between the external urethral meatus and anus. We report a case of median raphe cyst in the perineum presenting as a perianal polyp in a 65-year-old, English white male with exceptionally rare ciliated epithelium. According to our knowledge, this is the third such case of ciliated median raphe cyst in the English literature. This case, also the first case of ciliated median raphe cyst in the perineum location, focuses on pathogenesis of median raphe cyst.
正中缝囊肿是一种非常罕见的良性先天性病变，主要发生于阴茎腹侧，但也可出现在尿道外口与肛门之间的中线任何部位。我们报告一例65岁英国白人男性会阴部正中缝囊肿，表现为肛周息肉，其上皮为极为罕见的纤毛上皮。据我们所知，这是英国文献中第三例此类纤毛正中缝囊肿病例。该病例也是会阴部纤毛正中缝囊肿的首例，重点探讨正中缝囊肿的发病机制。
