Two Cases of Proliferating Trichilemmal Tumors Occurring in Unusual Sites
Abstract
- Proliferating tumor is one of rare benign tumors of skin appendage. It is usually solitary, more common in women after the fourth decade of life, and is almost exclusively confined to the scalp and back of the neck. We report herein two cases of proliferating trichilemmal tumor which occurred not on the scalp but on unusual sites. In the first case a 28 year-old woman had a pedunculated reddish mass with verrucous surface measuring 1.5cm in diameter in the opening site of the left external auditory canal. Shave biopsy and electrodesiccation was done for the purpose of histopathologic study and treatment. In the second case a 13 year-old girl had a dome-shaped pink colored papule measuring 0.3cm in diameter on the left elbow joint area. Excision biopsy was done. No recurrence was observed during he follow up period of 28and 12 months respectively in both cases.
