Syringocystadenoma papilliferum of the lower limb with ulceration

Abstract

Syringocystadenoma papilliferum is an exceedingly rare skin adnexal neoplasm of apocrine gland origin, commonly located primarily on the scalp and appearing as a hairless nodular plaque lesion. We report the case of a 35-year old man with history of an ulcer on the right leg which started three years earlier as a small excoriation after trauma to the leg over a lesion present from birth. Histological examination confirmed the diagnosis of syringocystadenoma papilliferum, which is a very rare lesion on the leg. We report this case due to its rarity and unusual clinical presentation.
