Anterior view of a child’s face showing numerous perioral papillomas, which developed as a result of the treponemal disease known as yaws. The first sign of yaws is the appearance of a painless papule, which grows into a papilloma. These large, early granulomatous lesions are highly infectious and display a yellow, crusty surface.
