A Case of Concomitant Tinea Infection Diagnosed with Molecular Biologic Technique / 대한의진균학회지

ABSTRACT

Trichophyton(T.) rubrum is known to be the most common causative agent of tinea cruris, tinea corporis, and tinea pedis, and hygiene, nutritional status, and high temperature/humidity are known to play an important role in pathogenesis. Although there has been a report on a case of co-infection in which tinea pedis subsequently developing tinea cruris with the foot lesion being a reservoir of the later lesion, there is of yet no report which confirmed co-infection of two different lesions through identification of definite causative organisms. This case concerns a 32 year-old patient who presented with erythematous annular scaly patches on the groin and axilla. Although no organism was identified on mycosel culture, DNA base sequence and RFLP analysis of the scales revealed T. rubrum in both of the lesions. Considering that this is a rare case of tinea cruris accompanied by tinea corporis in the axilla and groin confirmed by molecular biological techniques, the authors present it with review of literature.
