A type of skin growth or mark that can be present at birth or develop later, often pigmented and can appear as a mole or birthmark.
The doctor examined the nevus on her arm to ensure it was not harmful.
Nevus comes from Latin 'nævus' (meaning a birthmark or mole). The word refers to a benign skin lesion that is often present at birth or develops shortly after.
Think of a 'birthmark' — that's what a nevus is, a mark that can be present from birth.
