Meat nevus is the common name for intradermal nevus. Intradermal nevus mainly manifests as localized hyperplasia on the surface of the skin, which may be caused by the proliferation or accumulation of localized melanocytes, or it may be caused by prolonged exposure to sunlight.
1. Melanocyte hyperplasia: when local melanocytes in the epidermis accumulate and undergo benign hyperplasia, melanin pigmentation and nevus formation may appear on the skin surface. This kind of nevus usually appears as a small-sized black nevus and usually grows slowly. However, repeated breakage or infection may also cause melanoma, so you can consider laser or other ways to remove it.
2. Exposure to sunlight: If you do not take proper measures to protect yourself from sunlight when the sun is shining strongly, it may cause the appearance of nevus.
After the appearance of nevus, it is recommended to go to the hospital for examination in time, and you can choose the appropriate treatment under the guidance of the doctor.
