Description

A rare lesion, a subcutaneous dermoid cyst, behind the ear, is discraibed. A 35-year-old Japanese female with an erythematous, raised lesion behind the left ear, that had been present since 20 years ago, developed a few days before presentation. Though epidermoid cyst was clinically considered, multiple hairs were found on sectioning. The cyst measured 10×20 mm, didn′t invade the periosteum. Histopathologically the subcutaneous tumor is lined by an epidermis, showed hyperplastic sebaceous glands and hair follicle in wall. No relapses occurred within 4 months.
