A macule is a flat, distinct, discolored area of skin. It's a type of skin lesion that doesn't involve any change in skin texture or thickness. Macules are usually small, less than 1 cm in diameter, and can be caused by a variety of factors, including:
- Freckles and age spots: These are common examples of macules, often caused by sun exposure.
- Infections: Certain skin infections, like fungal infections, can cause macules.
- Skin conditions: Macules can be a symptom of conditions like vitiligo (loss of skin pigmentation) or psoriasis.
- Medications: Some medications can cause skin discoloration, leading to macules.
- Skin cancer: In rare cases, macules can be a sign of skin cancer, especially if they are changing in size, shape, or color.
It's important to note that not all macules are cause for concern. However, if you notice a new macule or one that is changing, it's always best to consult a dermatologist for proper diagnosis and treatment.
