Bowen's Disease in Dermoscopy

Abstract

Bowen's disease, named after John Templeton Bowen, also known as squamous cell carcinoma in situ is a type of non-melanocytic intraepidermal malignancy. It is estimated that in general population around 3% to 5% of Bowen's disease transform into invasive squamous cell cancer. Dermoscopy aims in the identification of the Bowen's disease. The most typical dermoscopic features of Bowen's disease include glomerular vessels and scaly surface. Although dermoscopy of Bowen's disease has been well established other skin lesions may present similar or identical structures in dermoscpic images leading to differential diagnosis dilemmas. Histopathological confirmation should be obtained prior the treatment of suspected cases of Bowen's disease in order to avoid a misdiagnosis.
