In the context of solar lentigines, what are liver spots?

Liver spots, commonly known in the dermatological field as solar lentigines, are characterized by numerous spots of yellowish-brown discoloration on the skin. These spots typically appear on areas that are frequently exposed to sunlight, such as the face, hands, and arms, particularly as people age. They result from an increase in melanin production due to prolonged UV exposure, leading to localized pigmentation. The correct choice highlights the condition of these spots and their appearance, making it essential for identifying sun damage and understanding skin changes over time.

Other choices do not represent the actual characteristics of liver spots; for instance, birthmarks refer to various skin lesions present at birth, bright red skin tumors fall under different dermatological conditions, and areas of extreme dryness relate to skin texture and hydration issues, not pigmentation changes.
