Surgical treatment: it is suitable for any type of pigmented nevus, and a comprehensive and thorough pathological examination can be performed. Through plastic surgery, the treatment effect is also ideal, which can not be achieved by non-surgical treatment. Surgical treatment can be based on the type, location and area of pigmented nevus, such as excision and suture, excision of skin graft and local skin expander. However, there will be scars after the operation.
