Causes
Discoid eczema
The causes of discoid eczema include an unknown etiology, although dry skin may contribute to its development. There may be an association with Staphylococcus aureus infection. Precipitating factors can include localized injury such as scratch, insect bite, or thermal burn, impetigo or wound infection, contact dermatitis, dry skin, and varicose veins (varicose eczema). It is more common in older adult males and younger adult females, with an association with chronic alcoholism in males. Additionally, drug-induced discoid eczema may occur due to medications causing skin dryness.
