There are various types of warts, including
flat (plane)
raised (common) and
verrucas (plantar).
They are benign epidermal tumours which are contagious (human papilloma virus, HPV) and all can be treated. Warts can develop individually or in clusters and can spontaneously disappear. Plane or flat warts occur mostly on the face, backs of hands, and wrists.
Hygiene must be of the highest importance to avoid cross-infection, and if not treated, it may spread.
Treatment methods
Treatment is performed using medicines, medical products, cryotherapy, and diathermy.
