Atypical presentations of Bowen's disease: A case series

Abstract

Bowen's disease (BD) is a rare premalignant condition. Classically, it presents as a well-demarcated erythematous plaque. Atypical variants in terms of the site (genitals and back) and morphology such as verrucous, hyperkeratotic, atrophic, and pigmented types are rarely described in the literature. This is the first case series of atypical presentation of BD. We herein report five cases of BD diagnosed clinically and histopathologically, presenting with rare morphology over unusual sites. They were treated successfully with both medical and surgical modalities. BD can be a diagnostic challenge for a physicians as it mimics common conditions such as psoriasis and eczema. This case series is reported to bring awareness regarding such unusual presentation and sites of BD for early detection and treatment among dermatologists, thus preventing malignant transformation.
