title: Disseminated dermal Trichophyton rubrum infection - an expression of dermatophyte dimorphism?
abstract: We present a case of disseminated dermal infection caused by Trichophyton rubrum (T. rubrum). This rare variant of dermatophytosis has an atypical clinical and histopathological presentation and occurs exclusively in immunosuppressed patients. The large, broad, pleomorphic hyphae with scattered budding arthrospores in this variant of T. rubrum infection are unusual and may represent expression of dermatophyte dimorphism previously described in vitro.
