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 (dating back to childhood) close to the medial end of the left eyebrow and overriding the anterior medial part of superior orbital rim. The lesion was completely excised and had not reoccurred during over four years of follow-up. (C) 2009 King Saud University. All rights reserved.
