Common moles are pigmented nevi, which usually do not go away on their own. Pigmented nevus, a benign neoplasm composed of nevus cells, is also a common benign tumor of the skin, which can occur in any part of the skin. Clinical manifestations are uniformly colored, well defined, brown or black spots or papules. Generally no special treatment is needed, but it usually does not disappear by itself, and can be removed by laser, surgery and other treatments. 1. Laser treatment: CO2 laser is commonly used to vaporize and smash the nevus directly, so as to achieve the purpose of removing the pigmented nevus. 2. Surgery: For larger nevi, or when there is a suspicion of malignant tendency, they can be surgically removed and histopathological examination can be perfected. If you want to remove pigmented nevus, you should go to regular medical institutions and follow the doctor’s instruction to carry out the relevant treatment.
