Mycosis fungoides in children and adolescents

Mycosis fungoides (MF) is a low-grade lymphoproliferative disorder that is histologically characterized by an epidermotropic proliferation of small or medium-sized atypical T lymphocytes with cerebriform nuclei and is primarily a disease of the elderly. It is rare in children and adolescents; in large series of MF published in the literature, only a small percentage of patients were observed to have onset of MF below adolescence. It was believed that a younger age of onset of MF may herald a poorer prognosis. Recently, with improved knowledge of the basic nature of the disease and refined diagnostic facilities, a few series of MF among children and adolescence have appeared and have drawn more awareness to the behavior of MF in this age group. This review summarizes the clinicoepidemiological features, treatment and prognosis of MF among children and adolescents based on the current literature.
