Skin Lesion

A skin lesion is a part of the skin that has an abnormal growth or appearance compared to the skin around it.
Two categories of skin lesions exist: primary and secondary.
Primary skin lesions are abnormal skin conditions present at birth or acquired over a person’s lifetime.
Secondary skin lesions are the result of irritated or manipulated primary skin lesions. For example, if someone scratches a mole until it bleeds, the resulting lesion, a crust, is now a secondary skin lesion.
