Nevus flammeus

Nevus flammeus is a type of birthmark that is present at birth and is characterized by its red or purple color. It is also known as a port-wine stain due to its coloration.

Causes

The exact cause of nevus flammeus is unknown, but it is believed to be due to a defect in the blood vessels of the skin. This defect causes the blood vessels to be wider than normal, which leads to the characteristic red or purple color of the birthmark.

Symptoms

Nevus flammeus is usually present at birth and does not change in size or shape over time. The birthmark can appear anywhere on the body, but it is most commonly found on the face. The color of the birthmark can vary from a light pink to a dark purple.

Diagnosis

The diagnosis of nevus flammeus is usually made based on the appearance of the birthmark. In some cases, a biopsy may be performed to confirm the diagnosis.

Treatment

There is no cure for nevus flammeus, but treatments are available to lighten the color of the birthmark. These treatments include laser therapy and cosmetic surgery. However, these treatments are not always successful and can have side effects.

Prognosis

The prognosis for individuals with nevus flammeus is generally good. The birthmark does not cause any health problems and does not increase the risk of developing other medical conditions. However, some individuals may feel self-conscious about the appearance of the birthmark.
