Question

Quizplus · Accepted Answer

A nevus, or mole, is a benign pigmented or nonpigmented lesion that forms from melanocytes beginning at ages 3 to 5 years. Over time the cells move down into the dermis and the nevi become nodular and symmetrical without irregular borders. Nevi may undergo transition to malignant melanomas. Nevi repeatedly traumatized, irritated by clothing, or large lesions can be excised.
