A wart is a benign skin tumor that occurs at the site of a violation of epithelial cell division. Warts can exist for a long time without reminding them of themselves.
They can be of any size and color. Most often they are flat because they are located on the surface of the skin. Although there are different types of warts, the most common is the common flat wart or callus. There are also several other varieties, such as pointed, filamentous or common.
