Dermoscopic findings in bowenoid papulosis: report of two cases.

Bowenoid papulosis (BP) corresponds to an in situ squamous cell carcinoma (SCC) located in the anogenital region. It is related to HPV, and presents with gray-brown elevated papules or plaques. A biopsy is needed to confirm the diagnosis; however, dermoscopy may be useful to differentiate this disease from other conditions, such as genital warts, seborrheic keratosis and lichen planus.
