Flat warts - Definition

February 2017


Definition


Warts are contagious lesions on the skin caused by a virus, the HPV or human papillomavirus. They form a small tumor on the skin or mucosa, appearing in different areas of the body and in different forms depending on the type of HPV, which exists in more than 120 different sub-types. Flat warts are caused by HPV 3, and manifest as small raised lesions that are smooth, most often affecting the face or the back of the hands. They can remain for years, and cause itching.
