The syndrome of tinea pedis caused by human-adapted Trichophyton mentagrophytes (interdigitale) can be recognized by two signs not characteristically seen in tinea pedis caused by T. rubrum and Epidermophyton floccosum:1 bullous > 2 mm vesicles in the thin skin of the plantar arch and along the sides of the feet and heel adjacent to the thick plantar stratum corneum,2 and white superficial onychomycosis. The relationship of the syndrome to zoophilic T. mentagrophytes remains in question.
