Extramammary Paget's disease of the penis: A rare case report.

Extramammary Paget's disease (EMPD) of the penis is a rare, intraepidermal adenocarcinoma. We describe the case of a 60-year-old male who presented with an erythematous plaque on his penis, previously treated with various topical and oral drugs. Punch biopsy from the lesion revealed the diagnosis of EMPD. Early diagnosis and treatment is necessary for this rare neoplastic condition.
