Rectal blue nevus: Case report of a rare entity and literature review.

Blue nevus, a pigmented skin lesion, affects the dermal melanocytes that are rich in melanin. Its occurrence on skin has been well described in literature. Less commonly, involvement of mucosal surfaces especially genitourinary tract has also been noticed. Here we present a rare case of a blue nevus involving the rectum. So far there has been only one prior description of the blue nevus involving the gastrointestinal mucosa. Differentiation of this lesion from melanoma is the key. Simple excision of the blue nevus with a biopsy forceps during the colonoscopy is an effective management.
