Abstract

Keratoacanthoma centrifugum marginatum (KCM) is characterized by a rapidly growing verrucous tumor with progressive peripheral expansion and central clearing. It usually arises from hair bearing and sun exposed skin among lighter skin phototypes. It closely resembles verrucous carcinoma, mycobacterial or fungal infections clinically, hence a biopsy is indispensable to establish the diagnosis. We report an interesting case of KCM in a Filipino, which was initially thought of as either verrucous carcinoma or a chronic infection and was successfully treated with wide excision with split thickness skin graft.
