We report a case of pigmented Bowen's disease in the periungual region treated with Mohs micrographic surgery. Bowen's disease is a squamous cell carcinoma in situ. Although it is a common condition, the pigmented form is rarer, with periungual localization being even more uncommon. Pigmented Bowen's disease presents clinically as a non-uniform, desquamous or verrucous brownish lesion, and it is often confused with other diseases (pigmented actinic keratosis, seborrheic keratosis, melanoma, basal cell carcinoma, nevus). Dermoscopy is of great diagnostic and therapeutic value and is important in the evaluation of recurrence.
