What is a macule?

A macule is defined as a flat spot or discoloration of the skin that is typically less than one centimeter in diameter. It does not have any elevation and is usually distinguished from surrounding skin due to its color difference. Common examples of macules include freckles, flat moles, or other hyperpigmented areas. Understanding the characteristics of a macule is important in the study of skin disorders and conditions, as it helps differentiate between various types of skin lesions and their presentations. Other terms, like "raised bump," "hard lesion," or "fluid-filled sac," refer to different types of dermatological presentations and are not suitable descriptions for a macule.
