Syringocystadenoma Papilliferum of Atypical Location

Abstract

Syringocystadenoma papilliferum is a rare benign adnexal tumor, commonly located in the cephalic segment and usually associated with a sebaceous nevus. Clinically, it may resemble several neoplastic lesions, but histopathology is very characteristic. Surgical removal is the definitive treatment. The occurrence of this lesion on the nipple, as presented below, is extremely rare, although already described. A 47 years’ old female patient reported a vegetating lesion on the right nipple, present for 8 months, occasionally with exudation. On examination, a vegetating nodule with a papillomatous and erosive surface measuring about 2 cm was observed adjacent to the nipple. Surgical excision with a narrow margin was performed. Histopathology showed the typical aspect of papillary syringocystoadenoma.
