title: Chronically recurrent and widespread tinea corporis due to Trichophyton rubrum in an immunocompetent patient.
abstract: A 31-year-old immunocompetent male who presented with a 4-year history of extensive erythematous and scaly plaques involving the abdomen, gluteal and inguen regions with concomitant tinea pedis and onychomycosis is described. Diagnosis was based on positive mycological examination and positive histopathologic examination. Species identification was performed by growth on Sabouraud dextrose agar and by sequencing of the internal transcribed spacer regions of the rDNA region. The pathogen identified was Trichophyton rubrum. The same fungal species was cultured from his abdominal, gluteal, foot and toenail. A combination therapy with systemic terbinafine and topically applied terbinafine cream was successful. A 1-year follow-up did not show any recurrence of infection.
