Nevus cell

Nevus cell is a type of cell that is found in the skin. These cells are responsible for the formation of moles and other types of skin lesions. Nevus cells are derived from melanocytes, which are the cells that produce melanin, the pigment that gives color to our skin, hair, and eyes.

Origin and Function

Nevus cells originate from melanocytes, which are located in the basal layer of the epidermis. They are usually round or oval in shape and have a large nucleus. Nevus cells produce melanin, which is transported to the surrounding keratinocytes to provide color to the skin and protect it from UV radiation.

Nevus Cell Aggregates

When nevus cells group together, they form a nevus. This can occur in the epidermis, dermis, or both. The appearance and characteristics of the nevus can vary depending on the location and arrangement of the nevus cells. For example, a compound nevus contains nevus cells in both the epidermis and dermis, while an intradermal nevus contains nevus cells only in the dermis.

Clinical Significance

Nevus cells are benign in nature. However, changes in their size, shape, or color may indicate the development of a melanoma, a type of skin cancer. Therefore, regular examination of moles and other skin lesions is important for early detection and treatment of skin cancer.
