Pilomatricoma in perioral region

Abstract

Herein, we report a very rare case of pilomatricoma in the perioral region. A 27-year old Japanese female was referred to our clinic with a subcutaneous tumor in the angle of the left side of the mouth. The tumor was observed as a subcutaneous well-circumscribed and bony hard mass, without any changes of the skin surface, while a soft radiographic examination revealed a weak calcifying rounded mass. The tumor was extirpated using an intraoral approach, because of patient request. During the operation, the tumor was found to be partly attached to the surface skin, though easily removed from the surrounding tissue. The tumor was a rounded calcifying mass, 13 mm in diameter, and histologically diagnosed as a pilomatricoma.
