BACKGROUND
Syringomas usually develop in women as multiple skin-colored papules primarily seen on the periocular regions and cheeks. They can cause cosmetic problems and lead to poor self-esteem. Though several treatment modalities have been established, such as excision, electro/cryosurgery, chemical peeling, and CO2 laser surgery, none of them are satisfactory due to their limitations and side effects, for example, pain, prolonged healing time, postoperative erythema/pigmentary changes, and scarring.
OBJECTIVE
The objective of this study was to develop a new treatment method for syringoma and to minimize the side effects through selective destruction of the tumor.
METHODS
Six patients with multiple periorbital syringomas were enrolled in this study. The surface epithelium of the syringomas was vaporized by CO2 laser, and black ink was introduced in order to allow penetration to the dermis using iontophoresis. Subsequently the artificial tattoos were removed by Q-switched alexandrite laser. The results were evaluated clinically by both physicians and patients at 1, 2, 4, and 8 weeks after treatment.
RESULTS
The majority of syringoma in the six patients disappeared by the first follow-up 1 week after treatment. There were no cases of prolonged erythema persisting beyond 2 weeks. Additional treatment was repeated in the same manner in order to remove the remaining syringomas in one patient. There were no recurrences during the 8-week follow-up period.
CONCLUSIONS
Our new treatment was safer, less painful, nonscarring, and there was a quicker recovery period and less of a burden to repeat treatment when necessary.
