Revisiting Imiquimod for Treatment of Folliculotropic Mycosis Fungoides: A Case Report and Review of the Literature

Abstract

Folliculotropic mycosis fungoides (FMF) is an aggressive variant of mycosis fungoides (MF) characterized by infiltration of the hair follicle epithelium by neoplastic T cells. FMF demonstrates poor response rates to standard skin-directed therapies such as phototherapy and topical corticosteroids. Imiquimod, an immunomodulatory agent that stimulates the antitumor immune response, has been used successfully in treatment of early-stage MF. We report a 21-year-old patient with unilesional FMF who achieved clinical remission with imiquimod application. This case highlights a potential for use of imiquimod as a treatment option for patients with FMF and limited skin involvement.
