A case of perianal bowenoid papulosis: dermoscopic features and a review of previous cases

Bowenoid papulosis is an uncommon precancerous condition of the genitalia caused by oncogenic human papillomavirus types. It is seen in young, sexually active adults and histologically resembles Bowen's disease. Dermoscopy is useful in the diagnosis of both pigmented and non-pigmented skin lesions, but dermoscopic diagnostic accuracy criteria have not yet developed in diseases such as bowenoid papulosis and Bowen's disease. This case report analyzes the dermoscopic findings of bowenoid papulosis in the literature with the aim of increasing the frequency of use of dermoscopy in the diagnosis of bowenoid papulosis in clinical practice.
