A macule is a term used in dermatology to describe a small, flat, and non-raised area of skin that appears differently in color compared to the surrounding skin. It is typically less than 1 centimeter in diameter.

Macules can have various colors, including red, pink, brown, white, or even purple. The discoloration is caused by various factors such as an increase or decrease in the pigment-producing cells called melanocytes, inflammation, or blood vessel changes in the skin.

Here are a few examples of different types of macules:

1. Freckles: These are small brown macules commonly found on the face and other sun-exposed areas. Freckles are usually harmless and are caused by an increased production of melanin in certain areas of the skin.

2. Café-au-lait spots: These macules are light brown and have a coffee-with-milk appearance. They are often present at birth or develop in early childhood. Café-au-lait spots can be associated with certain genetic conditions like neurofibromatosis or can occur as isolated findings.

3. Vitiligo: This condition causes the loss of melanocytes, leading to the development of macules with absent or reduced pigmentation. These macules are usually surrounded by normal skin color and can appear anywhere on the body.

4. Petechiae: These are small, pinpoint-sized macules that are red or purple in color and appear due to bleeding under the skin. Petechiae can be caused by various factors such as trauma, infections, or certain medical conditions.

It’s important to note that while macules do not have any specific elevation or texture changes, they can sometimes be a clue to an underlying medical condition. If you notice any unusual or concerning macules on your skin, it is always recommended to consult a dermatologist for proper evaluation and diagnosis.
