[Cultural protection of a bullous form of Tinea pedis]

Abstract

While maceration, hyperkeratosis and vesicles are well known as typical clinical correlates of dermatophyte infection of the feet it seems to be still controversial if bullae also belong to the clinical spectre. In a 48-year-old female Trichophyton rubrum could be cultured from the fluid obtained by aspiration of an interdigital bulla. In another case Trichophyton mentagrophytes could be isolated from the interdigital space but not from a bulla found on the sole microscopic investigation, however, being positive. This backs the hypothesis that blisters found on the foot can be due to the local presence of dermatophytes.
