Treatment of folliculitis decalvans is a major challenge, with a great number of recurrences and required maintenance of disease activity over a long period. Laser-based hair removal has been used in the management of scarring follicular disorders. The present case report aims to illustrate the case of a patient bearing folliculitis decalvans in the lower limb who underwent five therapeutic sessions of neodymium:YAG laser (Nd:YAG), achieving complete remission of the inflammatory lesions with the treatment.

The Hailey-Hailey disease or familial benign pemphigus is a rare condition, characterized by vesicular lesions and erosions with a predilection for intertriginous areas associated with pain and burning sensation that affect the quality of life of patients. There are many topical and systemic treatments for the injuries that can temporarily promote partial or complete remission, but there is no curative treatment. Some treatment options with lasting results include dermabrasion and Erbium laser resurfacing (YAG or CO2). We report three cases of patients with recurrent lesions and limited responses to classical treatments, which showed significant clinical improvement after fractional CO₂ laser therapy.
