A novel technique for the treatment of multiple trichoepitheliomas using a high-intensity diode laser

Background: Nonsurgical approaches have been introduced for the treatment of trichoepitheliomas, including erbium-YAG and CO2 lasers. Diode lasers have been used for the treatment of skin tumors such as hemangiomas and neurofibromas. Objective: To evaluate the efficacy and safety of a diode laser for the treatment of trichoepitheliomas. Patients and methods: Eleven patients with multiple trichoepitheliomas were treated with a continuous wave diode laser (980 nm) at a power of 5 W. Sessions were performed biweekly for a maximum of six sessions. Assessments of the patients’ lesions by count and size regression were performed before treatment and at weeks 4, 8, and 12. The patients were followed up for 12 months. A histopathologic evaluation was carried out before treatment and at 1 month after the end of treatment, of completely cleared lesions. Results: Ten patients completed the study. They received a mean of 3±1.7 laser sessions (range 1–6 sessions). A significant reduction in the mean number of lesions (P
