Abstract
- Proliferating trichilemmal cyst is a rare benign tumor of external root sheath origin that usually occurs on the scalp of elderly women. It is rarely found on the face, neck, trunk and back. A 17 year-old man presented with a skin-colored, subcutaneous, tender nodule on the elbow with a history of bee sting. A histological examination revealed a well demarcated multilobular cystic mass characterized by trichilemmal keratinization in the dermis. The skin lesion was totally excised and recurrence has not been found. We present a case of proliferating trichilemmal cyst of unusual predilection site.
