Moles are mainly categorized into intradermal nevus, junctional nevus and mixed nevus, and the treatment mainly includes physical therapy and surgery. 1. Intradermal nevus: Intradermal nevus is a benign skin tumor formed by proliferation of melanocytes, and its condition is generally stable. If it affects aesthetics or is worried about malignant changes, it can be treated by surgical excision. 2. Junctional nevus: Junctional nevus is a type of pigmented nevus, which is a benign skin tumor. If junctional nevus occurs in the exposed part of the skin and affects aesthetics, it can be removed by laser, freezing, chemical peeling and so on. If malignancy is suspected or there is a tendency of malignancy in pathological examination, it can be treated by surgical excision if necessary. 3. Mixed nevus: Mixed nevus mainly looks like junctional nevus with hair growth, and may have pathological changes of intradermal nevus and junctional nevus. If the mixed nevus obviously affects the beauty, it can be treated by laser, ionization and other physical methods if necessary. To sum up, there are more methods to remove moles, and patients are advised not to treat them by themselves, but can go to the dermatology department of the hospital, and the doctor will make a comprehensive judgment according to the onset of pigmented nevus’ location and size.
