A macule is defined as a flat spot or discoloration on the skin that is usually less than 1 centimeter in diameter. This characteristic distinguishes it from other skin lesions that may be raised, such as papules or pustules. Macules can come in various colors, including red, brown, or white, and they do not cause any change in the texture of the skin. Examples of macules include various types of birthmarks or freckles, where there is a change in pigmentation without any elevation or indentation of the skin surface. Understanding the definition of a macule is essential for differentiating it from other skin conditions that present differently.
