Abstract

Verrucous epidermal naevus (VEN) is a rare form of epidermal naevus. We present a case of VEN occurring over the perianal region of a 7-year-old boy. The lesion was initially thought to be an area of chronic dermatitis; however it was refractory to treatment. Histopathology confirmed the diagnosis of VEN. VEN in the inguinogenital region may be misdiagnosed as flexural psoriasis, genital warts or sexual abuse. This is what precisely happened to our patient for a duration of more than 1 year.

Keywords: Perianal; Verrucous epidermal nevus; Warts

Core tip: The most interesting feature of this case is the difficulty of diagnosing verrucous epidermal naevus (VEN) of the genital region. It is expected that genital lesions are troublesome entities with respect to accurate diagnosis. It is essential for pediatricians as well as dermatologists to consider VEN as a possibility in warty genital or perianal lesions to avoid inappropriate accusations and irrelevant investigations of child abuse.
