A 'naevus' is commonly known as a?

A 'naevus' is commonly recognized as a mole. This term refers to a benign skin lesion that often appears as a small growth on the skin, usually pigmented, and can vary in color and size. Moles can be present at birth or develop over time and are typically composed of clusters of melanocytes, which are the cells that produce melanin, the pigment responsible for skin color.

While the term 'birthmark' may refer to a variety of skin marks, including vascular lesions, not all birthmarks are classified as naevi. The most accurate identification for a naevus in common terminology is indeed a mole. Understanding this distinction is important in dermatology and esthetics, as it allows practitioners to correctly identify and manage various skin lesions.
