Definition

Noun: 1. A small, flat, brownish patch on the skin: A type of benign, localized hyperpigmentation, typically appearing on areas of skin frequently exposed to the sun, such as the face, hands, and forearms. Despite the name, these spots are not related to liver function or disease.

Examples of Usage

Advanced Usage

Notes on Meaning

• Important Clarification: The name "liver spot" is a historical misnomer. These spots have no connection to the liver, its health, or its function.
