Tinea corporis purpurica and onychomycosis caused by Trichophyton violaceum.

We report two cases of tinea corporis purpurica of the legs, presumably caused by self-inoculation of the mycete from the toenails, in two elderly women (80 and 78 years). Trichophyton violaceum was isolated from the skin and nails. Histological examination of a biopsy specimen from the leg lesions confirmed the diagnosis. The source of infection was an Ethiopian carer who had tinea capitis in the first case, and was undiagnosed in the second patient. Cases of purpuric variants of tinea corporis are rare and this is the first report of probable self-inoculation of T. violaceum from onychomycosis.
