A case of hidradenoma papilliferum on the cheek of an adult male

Hidradenoma papilliferum is a benign, cystic, papillary tumor that occurs almost exclusively in women on the skin of the anogenital region and this is usually a slow-growing cystic dermal mass that can be either asymptomatic or it can ulcerate and bleed, and it represents an adenoma with apocrine differentiation. Nonanogenital (ectopic) hidradenoma papilliferum is rare. We present here a case of hidradenoma papilliferum in a 52-year old male with an erythematous to brownish nodule on the left cheek and the lesion had the typical histopathological findings of hidradenoma papilliferum.
