Abstract

Bowen’s disease, an intraepitelial neoplasm of keratinocytes, is characterized by a sharply demarcated, asymptomatic, scaly or crusted, erythematous plaque that is slow growing. It may progress into invasive squamous cell carcinoma. It most commonly affects sun-exposed surfaces of elderly females. Herein we report a case of Bowen’s disease in the web-space of both feet for 1 year who was initially diagnosed as tinea pedis. The rarity of this presantation in dermatology is emphasized.

Summary

Introduction

Bowen’s Disease (BD), known as squamous cell carcinoma in situ, predominantly occurs in patients older than 60 years. BD of the interdigital space is very rare and may mimic various benign conditions such as tinea pedis or other web space infections [3]. We report an unusual case of BD arising in the interdigital space of both feet and emphasize the rarity of this presantation in dermatology. Examination revealed sharply marginated erythematous and crusted plaques, some of them with central maceration and fissures, in the web-spaces of the second, third, and fourth toes on the right foot and in the web-spaces of the fourth toes on the left foot (Figure 1).
