Paget disease of the male breast.

Paget disease of the breast is an uncommon tumor of the nipple-areola complex that usually presents as an erythematous and erosive lesion. We report the case of a 61-year-old man that presented with a three-year history of an erythematous lesion of the right areola, first treated with topical corticosteroids without benefit. He was then referred to our dermatology department and the clinical suspicion of Paget disease was considered. The diagnosis was later confirmed by biopsy. This case report highlights the importance of clinical recognition of this entity along with other diseases that mimic these skin changes in order to allow earlier diagnosis and proper follow-up.
