What type of skin lesion is a Nevus?

A nevus, commonly known as a mole, is classified as a benign skin lesion. Benign lesions are non-cancerous growths that do not invade surrounding tissues or spread to other parts of the body. A nevus usually appears as a small, dark spot on the skin, resulting from a cluster of pigmented cells. While most nevi are harmless, it's important to monitor them for any changes, as some could potentially develop into melanoma, which is malignant. Nonetheless, the classification of a nevus itself is benign based on its typical characteristics and behavior. Understanding this classification helps in recognizing the distinctions between different types of skin lesions and their implications for patient health.
