Mycosis Fungoides with Tinea Pseudoimbricata Owing to Trichophyton Rubrum Infection

Abstract

Dermatophytes can mimic or possibly trigger mycosis fungoides (MF). To present the case of a 55-year-old male referred for MF refractory to therapy who instead had extensive tinea pseduoimbricata (concentric, annular lesions secondary to Trichophyton rubrum). Case report with biopsy and cultures. Oral antifungal therapy dramatically improved his lesions, and only a few MF lesions persisted after treatment. Concurrent tinea may confound the treatment and diagnosis of MF.
