Deep Dermatophytosis to Trichophyton rubrum and T. verrucosum in an Immunosuppressed Patient

: A patient treated with immunosuppressant drug therapy for a non-Hodgkin's lymphoma and who presented with a tinea corporis developed a sudden outbreak of numerous subcutaneous nodules. Deep-seated hyphae and spores were found in skin biopsy specimens. There was no evidence of keratin debris or histologic features of granulomata and giant cells. Cultures from tinea and nodules grew Trichophyton rubrum and T. verrucosum. There are no more than 60 cases of deep dermatophytosis reported in the literature.
