Syphilis | Stages, Symptoms, Treatment & Prevention

2- Ulcers

Around 10 to 15% of patients with secondary syphilis start showing dry and superficial erosions in the skin. They have a silver-gray color with a red areola, and can be found in the mucosa of the palate, tongue, pharynx, larynx, gland of the penis, vulva, anal and rectum. These lesions are not pruritic but they are highly infective due to their high content of treponema.
