Applicability of Dermoscopy in the Atypical Presentation of Tinea Pedis: A Case Report

Abstract

Tinea pedis, also known as athlete’s foot or foot ringworm is an infection of the feet or toes with dermatophyte fungus [1]. Trichophyton rubrum is the most common isolate accounting for 70% of cases. Other species include Trichophyton interdigitale, Trichophyton mentagrophytes and Epidermophyton floccosum. The ideal conditions for fungal growth include hot and humid environment, prolonged use of occlusive footwear, excessive sweating and prolonged exposure to water [2]. The maceration of the skin due to above risk factors along with keratinases released by fungus helps in easy invasion of the keratin layer. The mannans contained in the fungal cell wall also further suppress the body’s immunity thus, contributing to tinea pedis. Herein we describe a case of recurrent vesiculobullous type of tinea pedis who was inappropriately managed previously.
