title: Trichoblastoma in a child.
abstract: A trichoblastoma is a benign adnexal neoplasm composed of follicular germinative cells. It most commonly presents as a solitary nodule on the scalp, face, or perineum and occurs equally in males and females. It is diagnosed most commonly between the fourth and the sixth decades, and it is extremely rare in childhood. To our knowledge there is no prior case report of a primary trichoblastoma occurring outside the setting of a nevus sebaceous of Jadassohn in a child before adolescence. Herein we report a case of trichoblastoma of the right cheek in an 11-year-old Korean girl.
