title: A case of trichoadenoma arising in the buttock.
abstract: A 41-year-old Japanese man with trichoadenoma on his buttock was described. Histological examination showed numerous horn cysts and some tumor islands consisting entirely of eosinophilic epithelial cells. A review of 24 reported cases of trichoadenoma revealed that most of them developed on the facial region (14 of 24 cases, 58%); the buttock (6 of 24, 25%) was the next most common site.
