Skin lesions are represented by two syphilides - Bugorkova and gummy. Bugorkova syphilides The main element is a small Bugorkova syphilides dense mound, which lies in the skin, hemispherical shape, the size of a cherry stone, dark red or red sinyushno-. Its surface is smooth and shiny. After a few weeks or months tubercle softens and ulcerate to form rounded, fairly deep ulcers with valikoobraznymi, sharply cut edges. Gradually the bottom of the ulcer is cleaned from the decay, covered with granulation and turns into the pigmented atrophic scar on the periphery, which had no new lesions. Group scarring has a mosaic look.
