What is nevus anemicus?

Nevus anemicus is a non-cancerous skin condition characterized by a pale, hypopigmented macule or patch, usually present at birth or developing in early childhood. It is caused by a lack of blood flow to the skin, which results in an area of skin that is lighter in color than the surrounding skin.

The size, shape, and location of nevus anemicus may vary, but it is most commonly found on the trunk and limbs. It is not usually associated with any other symptoms or complications and does not require treatment. However, it may be confused with other skin conditions, such as vitiligo or tinea versicolor, and a dermatologist should be consulted for an accurate diagnosis.

Nevus anemicus is considered a benign condition and is not associated with any increased risk of skin cancer or other health problems. It may, however, have a significant psychosocial impact, particularly if it is visible in areas of the body that are difficult to conceal.
