[Acanthoma fissuratum cutis]

Abstract

Acanthoma fissuratum cutis is a common, however not widely recognized cutaneous lesion induced by minor, constant mechanical traumas. Lesions occur typically on the side of the nose or behind the ear, as most cases are caused by poorly-fitting spectacle-frames. Clinical features of the benign reactive tumors, which occasionally may be mistaken for basal cell epitheliomas, are presented.
