Mycosis fungoides with tinea pseudoimbricata owing to Trichophyton rubrum infection.
BACKGROUND
Dermatophytes can mimic or possibly trigger mycosis fungoides (MF).


OBJECTIVE
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).


METHODS
Case report with biopsy and cultures.


RESULTS
Oral antifungal therapy dramatically improved his lesions, and only a few MF lesions persisted after treatment.


CONCLUSIONS
Concurrent tinea may confound the treatment and diagnosis of MF.
