What is a macule?

A macule is defined as a flat, distinct, discolored area of skin that is not elevated or depressed compared to the surrounding skin. It is typically less than 1 centimeter in diameter and is characterized by a change in skin color, which can be caused by various conditions, such as hyperpigmentation or inflammation. The key feature of a macule is that it does not have any texture above or below the level of the skin, differentiating it from lesions that are raised, filled with fluid, or involve changes in texture such as scar tissue. Understanding the definition and characteristics of a macule is essential for recognizing different skin conditions in a clinical context.
