Skin lesions refer to any variation in skin color or texture anywhere on the body. Some skin lesions are present at birth, such as moles, freckles, or birthmarks. Others are acquired over time, such as acne, warts, allergies, sunburn, or abrasions.
Most skin lesions are harmless. However, it is important to keep an eye on them because they can change over time, which may be indicative of a serious problem. For example, one pigmented lesion that can occur on the foot and lower extremity is malignant melanoma.
Kaposi’s Sarcoma is another cancerous lesion that may appear on the soles of the feet of people with HIV infection or AIDS.
