Periocular hidradenoma papilliferum

Hidradenoma is a benign adnexal neoplasm originating from the apocrine sweat gland, and is almost exclusively detectable in the skin of the anogenital area of middle-aged white females after puberty. Ectopic hidradenoma papilliferum, which involves the skin away from the anogenital region, is exceedingly rare, and can also affect males. We report a female patient with a lesion (datingback to childhood) close to the medial end of the left eyebrow and overriding the anterior medialpart of superior orbital rim. The lesion was completely excised and had not reoccurred duringover four years of follow-up.
