Trichoadenoma of vulva: A rare case with rare site of presentation

Abstract

Trichoadenoma is a rare benign adnexal tumor of skin with differentiation towards hair structure. It was first described by Niklowski in 1958 and so is also known as trichoadenoma of Nikolowski. It shares its features with trichoepithelioma and trichofolliculoma, which are the other common benign adnexal tumors with differentiation towards hair structure. Vulva being an unusual site for occurrence of trichoadenoma, there are very few cases reported in the literature at this site. Here we report a case of trichoadenoma of vulva. Keywords: adnexal tumor hair follicle differentiation trichoadenoma.
