Plexiform schwannoma of the clitoris

Abstract

Only three cases of clitoral schwannoma have been reported in the English language literature, with none of them being a plexiform schwannoma. Here we report the first plexiform schwannoma of the clitoris. A 41-year-old woman without neurofibromatosis presented with a 2 x 2 cm, slowly growing, painless tumor of the clitoris. Simple excision of the tumor was performed, and pathological examination revealed a plexiform schwannoma. No evidence of recurrence was noted after 2 years of follow-up. Despite its rarity, a schwannoma should be included in the differential diagnosis of a clitoral enlargement or mass. Our case, despite its unique plexiform growth pattern, has clinical features similar to those of other reported cases of clitoral schwannoma.
