Folliculotropic mycosis fungoides in an adolescent: A rare case

摘要

Folliculotropic mycosis fungoides (FMF) is an uncommon and aggressive form of mycoses fungoides with preferential involvement of head and neck region. Lesions of FMF present as erythematous plaques or papules with follicular prominences, acneiform lesions, cysts, nodules, patches of scarring alopecia, and prurigo-like lesions. The mean age of diagnosis is at 60 years and it is extremely rare in childhood and adolescence. We report a case of a 16-year-old male patient who presented with a 2-month history of an asymptomatic erythematous infiltrated plaque over the forehead. Histological examination was consistent with diagnosis of FMF. He was successfully treated with local electron beam therapy.
