Melongenoma, also known as melanocytic neoplasm, is a type of tumor that originates from melanocytes, the cells responsible for producing melanin in the skin. These neoplasms can be benign, such as moles (nevi), or malignant, like melanoma, which is a form of skin cancer. The diagnosis and management of melongenomas vary based on their characteristics, including size, growth patterns, and potential for metastasis. Regular skin checks and monitoring changes in existing moles are important for early detection and treatment.
