Lichen planopilaris developed during childhood.

Lichen planopilaris is a disease that appears with lymphocytic cicatricial alopecia. It is considered a follicular variant of lichen planus. The examination of affected areas shows alopecia with perifollicular erythema and scaling, revealing a predilection for hair follicles. The involvement of children is uncommon, with few reports in this population in the literature. This study presents a clinical case of a male patient of 15 years of age with characteristic lesions of lichen planopilaris.
