Comparison of microinsulated needle radiofrequency and carbon dioxide laser ablation for the treatment of syringoma.

Syringoma is a benign adnexal tumor originating from the intradermal eccrine ducts and predominantly occurs in women at puberty or later in life. We present a case of a 30-year-old woman with a 2-year history of syringoma on her neck and axillar region. She was treated with two devices in a split manner. The right-sided lesions of the neck were treated with one session of 10,600-nm carbon dioxide (CO2 ) laser ablation. The left-sided lesions were treated with microinsulated needle radiofrequency (RF) three times. After treatment, the lesions treated with CO2 showed hypertrophic scar formation, but the other side lesions treated with microinsulated needle RF showed a marked reduction in the size and number of lesions, without any adverse effects such as scarring and hyperpigmentation related to epidermal damage. The treatment of syringoma with microinsulated needle RF, which is insulated at the point of epidermal contact, results in good cosmetic outcomes. Syringoma, microinsulated needle RF, CO2 laser.
