Abstract

A 45-year-old woman at 14th week of pregnancy was admitted our hospital for pain with defecation. Proctoscopy revealed white polyp 20 mm in diameter at the dentate line. The lesion grew to 60 mm and she underwent transanal polyp excision at 26 th week pregnancy. Postoperative diagnosis was fibroepithelial polyp (FP) or fibroepithelial stromal polyp (FSP) , which show similar histological features. FPs are typically located in anus and caused by physical stimuli during defecation. FSPs are commonly found in female external genitalia, considered to be hormone sensitive and sometimes grow rapidly during pregnancy. However FSPs are rarely located in anus, we concluded this case is more appropriate to considered to be FSP.
