Macules are small, flat patches of discoloration that can appear on the skin and affect its color, usually appearing in a range from tan to light brown. Unlike other skin lesions, macules are typically smaller than a centimeter in diameter and are not raised on the surface of the skin. Additionally, they are non-palpable, meaning they cannot be felt by touching them. Macules can have a variety of causes, ranging from genetic and environmental factors to disease processes. In most cases, they are harmless and require no treatment; however, some can be an indicator of certain diseases, such as vitiligo, so it is important to get them checked out if they persist. In addition to the possibility of being indicative of disease, macules can also be caused by certain medications, skin injuries, and hormonal changes. Given their relatively painless and benign nature, macules are generally not of great concern; however, it is still essential to keep an eye on them and seek medical advice if they do not resolve on their own. Typically, the discoloration will diminish within a few months, although if not treated, some macules may persist for years. To ensure macules are not indicative of anything serious, regular visits to the dermatologist are recommended.
