Liver spots

Definition:

Liver spots are flat brown-black spots that usually occur in sun-exposed areas of the body. They are also called age spots. They are unrelated to the liver or liver function.



Alternative Names:
Sun-induced skin changes - liver spots; Senile lentigines; Lentigos; Skin spots - aging; Age spots

Causes, incidence, and risk factors:
Liver spots are changes in skin color associated with older skin. The increased pigmentation may be brought on by aging, exposure to sun or other forms of ultraviolet light, or other unknown causes.

Liver spots are extremely common after 40 years old. They occur most often on the backs of the hands, on the forearms, shoulder, face, and forehead. These are the areas of highest sun exposure.

They are harmless and painless, but they may affect the cosmetic appearance. Occasionally, liver spots may mask the diagnosis of skin cancers.
