Folliculotropic mycosis fungoides in a pediatric patient mimicking black dot tinea capitis.

Immunosuppression following organ transplantation is a known risk factor for the development of lymphoproliferative disorders. Mycosis fungoides, a rare entity in pediatric patients, has seldom been reported as a post-transplant lymphoproliferative disorder. We report a case of folliculotropic mycosis fungoides in a pediatric patient following liver transplantation that was initially diagnosed as tinea capitis.
