Erythema elevatum diutinum is a rare chronic skin disorder characterized by persistent, raised, red or purplish lesions on the skin. The condition typically affects the hands, feet, elbows, and knees, but can occur in other areas of the body as well. Erythema elevatum diutinum is considered a type of cutaneous vasculitis, which is a condition characterized by inflammation of the blood vessels within the skin.
The exact cause of erythema elevatum diutinum is unknown, although it is believed to be related to autoimmune factors or an abnormal immune response. It may also be associated with other underlying conditions such as infections, rheumatic disorders, or malignancies. The condition is more commonly seen in adults, particularly in individuals with certain autoimmune diseases such as rheumatoid arthritis or HIV.
Symptoms of erythema elevatum diutinum include the formation of firm, red or purplish nodules or plaques on the skin that may be painful or itchy. Over time, these lesions can become thickened and form a hardened, yellowish appearance. In some cases, the skin lesions may ulcerate or become infected. The condition is typically chronic, with intermittent periods of worsening and improvement.
Treatment options for erythema elevatum diutinum typically involve managing the underlying condition, if present, and alleviating symptoms. This may include the use of immunosuppressive medications or corticosteroids to reduce inflammation and suppress the immune response. Additionally, topical treatments, such as potent corticosteroid creams or ointments, may be used to relieve symptoms and promote healing. However, due to the rarity of the condition, treatment approaches may vary and should be tailored to each individual case.
