It is most commonly seen in middle-aged adults, and is more common in women than in men. The cause of NXG is unknown, but it is thought to be related to an abnormal immune response. Symptoms may include itching, burning, and pain in the affected area. Treatment typically involves topical or systemic corticosteroids, and in some cases, immunosuppressive medications.
