Efficacy of diode laser for treating acne keloidalis nuchae.

Acne keloidalis nuchae is usually treated with oral antibiotics, local antiseptics or intralesional steroids but with limited success. I assessed the efficacy of diode laser for treating the inflammatory and keloidal papules of acne keloidalis nuchae in two cases. The lesions in both the cases showed about 90 to 95% clearance after 4 treatment sessions at one to one and half month intervals. No new lesions were observed during the follow up period of six months after the last laser treatment. Thus, after clearing bacterial infection, laser hair epilation can be used as the first line of therapy for treating papules of acne keloidalis nuchae. This is the first attempt at treating acne keloidalis nuchae with a diode laser.
