%X Dissecting cellulitis of the scalp (DCS) is a rare recurrent inflammatory disease of unknown etiology. Ideal treatment of DCS remains unclear. We treated DCS with 2940-nm erbium Yttrium-aluminum-garnet (YAG) laser in 12 patients and assessed the efficacy by Physicians Global Assessment (PGA), number of inflammatory nodules, abscesses, and area of alopecia. After a mean treating session of 2.2 months, 10 patients reached PGA 0 (initial PGA 1) or 1 (initial PGA ≥2). At the end of treatment, there was 84%, 100%, and 74% regression in nodules, abscesses, and alopecia area, respectively. No severe adverse effect was observed. 2940-nm erbium: YAG laser may be an effective and safe way to treat DCS resistant to other therapies.
