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.
