Nevus, medically known as nevus cells or melanocyte nevus, are skin manifestations caused by the increase of melanocytes in epidermis and dermis.
If it is papule or nipple-like appearance or pedicled skin, it is clinically called intradermal nevus; Slightly higher than the leather surface is mostly mixed mole; Not higher than the skin surface is the borderline nevus.
Extended data:
From the dermatological point of view, pigmented nevus is a very common benign skin tumor, which can be divided into many kinds. Histologically, pigmented nevus can be divided into borderline nevus, mixed nevus and intradermal nevus. Borderline nevus is usually flat on the skin surface, and the cell nest of nevus is limited to epidermis in pathology. Mixed hydatidiform mole can slightly bulge on the skin surface, and its nevus cell nest involves both epidermis and dermis.
