Cutaneous melanomas, a type of skin cancer, originate from specialized epithelial cells called melanocytes. Melanocytes are responsible for the production of melanin, the pigment that gives skin its color. These cells are primarily located in the epidermis, the outermost layer of the skin. When melanocytes undergo mutations, they can proliferate uncontrollably, leading to the formation of malignant tumors known as melanomas. Factors such as UV radiation exposure, genetic predisposition, and certain pre-existing skin conditions can increase the risk of melanoma. Early detection and treatment are crucial, as melanoma can be aggressive and metastasize to other parts of the body if not treated promptly.
