title: The incidence of skin manifestations by dermatophytes in patients with psoriasis.
abstract: Thirty-four psoriatic patients (23 males, 11 females) were found to have skin manifestations of dermatophyte infection. Tinea pedis was observed in 20 cases, tinea cruris in 6 and tinea manuum in 2. T. rubrum was the causative agent in all of these with the exception of 2 cases caused by E. floccosum. Lesions of tinea corporis were found intermingled with psoriatic plaques in various areas of the body skin in 6 patients (4 males, 2 females); T. rubrum was isolated from 5 of these and M. canis from one. Twenty-one of these psoriatic patients also had lesions caused by C. albicans in the toe-webs and interdigital aspects of the fingers, the latter being associated with paronychia in 9 cases. These findings indicate that we should remain aware of the possibility of fungus manifestations in patients with psoriasis, which would not appear to be an exceptional occurrence.
