Porokeratoma is an entity defined as an acanthoma with porokeratosis characteristics. It has a distinct histological pattern from that of the cornoid lamella and has clinical differences regarding the typical porokeratosis. The condition has been described only recently and there are few cases reported in the literature. The authors report the case of a 46 year-old male patient with an exophytic nodular lesion located in the intergluteal region. Histological examinations evidenced multiple cornoid lamellae, with those located on the periphery being better defined. Based on the clinical and histological appearance, the lesion was diagnosed as a porokeratoma.
