1,450‐nm Diode Laser in Combination with the 1550‐nm Fractionated Erbium‐Doped Fiber Laser for the Treatment of Steatocystoma Multiplex: A Case Report

Steatocystoma multiplex (SM) is a rare condition characterized by multiple, small, asymptomatic dermal cysts. Treatment options are limited, with varying degrees of success; these include oral isotretinoin, surgical excision or drainage, and liquid nitrogen cryotherapy. The most effective method is excision, but cosmetic considerations, time, overall cost, and pain must be considered, because patients tend to have multiple cysts. Lasers, especially nonablative devices, have not frequently been used to treat SM. Herein, we present the case of a patient with isolated steatocystoma multiplex on the abdomen and lower chest with substantial clearance after two laser treatment sessions using two complementary lasers: a 1,450‐nm diode laser to target the abnormal sebaceous glands and a 1,550‐nm fractionated erbium‐doped fiber laser to target the dermal cysts.
