Trichoepithelioma: successful treatment with the argon laser.

The cosmetic concern associated with multiple trichoepitheliomas is obvious. Previous modes of therapy have proven to be only temporary. However, multiple trichoepitheliomas appear to respond to the thermocoagulation and epidermal atrophic effects of the argon laser without recurrence over an extended follow-up period. Although these lesions are not as highly vascular as port-wine hemangiomas, their dramatic response to the argon laser is similar. This report documents a case of multiple trichoepitheliomas treated successfully with the argon laser from the face and scalp of a 29-year-old white woman. The benefits of the argon laser in treatment of multiple trichoepitheliomas include eradication of the lesions without apparent recurrence, restriction of spread of solitary trichoepithelioma into adjacent tumors, and prevention of obstruction of the periorbital region and auditory canal. The treatment may be accomplished as a simple outpatient procedure under local anesthesia with minimal pain or disability.
