Nevus
Commonly referred to as a mole. A nevus (plural is nevi) may be light brown to almost black and may have hair growing from it. They usually appear after 5 yrs of age, but can develop earlier. If the mole is large, changes color, or grows you should report this to your doctor. Occasionally, moles may become malignant. Small moles are common; the average light skinned adult has 10-30 of them.
