Pigmented Bowen’s disease (Bowenoid Papulosis) dermoscopically mimicking melanoma

Abstract

Pigmented Bowen's disease (PBD) is a rare clinical type of Bowen's disease (BD) and accounts for less than 2% of all cases 1-3. BD and bowenoid papulosis are considered the same entity 4. It is important to distinguish PBD from other pigmented skin lesions such as solar lentigo, pigmented actinic keratosis, keratoacanthoma, pigmented eccrine poroma, angioma, angiokeratoma, seborrheic keratosis, benign lichenoid keratosis, pigmented basal cell carcinoma, Spitz/Reed nevus, blue nevus, melanocytic nevi, and melanoma 1-3. Dermoscopy is a useful non-invasive method for differential diagnosis of pigmented lesions. Herein we report a 51-year-old man with PBD which is dermoscopically mimicking melanoma.
