discoid lesions

Discoid lesions are round or oval areas of skin that become thickened, scaly, and sometimes discolored. They often have a well-defined border, resembling a coin or disc, and may cause itching or discomfort. These lesions are commonly associated with certain skin conditions, like discoid lupus erythematosus, a chronic autoimmune disorder that affects the skin. They can appear on various parts of the body, especially areas exposed to the sun, and may lead to scarring if not properly managed. Diagnosing involves examining the lesions and possibly performing skin tests or biopsies.
