Porocarcinoma over scalp: A rare entity

Abstract

Porocarcinomas are aggressive adnexal tumors with a rare incidence. They are usually seen as a nodular or infiltrating growth over the lower extremities, infrequently over the scalp. They are thought to be arising from a pre-existing lesion and with a long clinical history. Treatment of choice is surgical resection with histopathologically confirmed negative margins. There are chances of local recurrence; hence a regular follow-up is must in these cases. Hereby we present a case of 42 year old male with 2 year history of growth over the right temporo-parietal region of the scalp. Histological confirmation of the diagnosis was done after wide local excision of the tumor. Porocarcinomas are mostly likely to be misdiagnosed clinically; therefore a histopathological correlation is necessary for the confirmation of diagnosis and further management of the patient.
