Congenital melanocytic nevi (CMN) represent benign proliferations of melanocytes present from birth, varying considerably in size, morphology and distribution. In some instances, particularly when ... Melanocytes describe a specialized type of cell that generates a substance called melanin, a pigment responsible for skin and eye color.
Understanding the Context
When several melanocytes cluster together, they form a benign, ... The dysplastic nevus initially was described in the 1980s as a mole with increased risk of developing melanoma and requiring total removal. However, dermatopathologists now consider dysplastic nevi to ...

They are mostly found in sun-exposed areas; however, they also can be found in sun-protected ... Study describes differences between mutation profile of acral nevi and acral melanoma Through a process called melanogenesis, melanocytes produce melanin, which is a pigment found in the skin, eyes, hair, nasal cavity, and inner ear. This melanogenesis leads to a long-lasting pigmentation, which is in contrast to the pigmentation that originates from oxidation of already-existing melanin. Melanocyte, specialized skin cell that produces the protective skin-darkening pigment melanin. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere—e.g., in the matrix of the hair.
