Scleredema, also known as Buschke disease, scleredema of Buschke, and scleredema adultorum, is a rare, self-limiting skin condition defined by progressive thickening and hardening of the skin, usually on the areas of the upper back, neck, shoulders and face. The skin may also change color to red or orange. The disease was discovered by Abraham Buschke. Although the cause of scleredema is unknown, it is usually associated with a disease, usually diabetes, a viral illness or strep throat. It is usually not fatal, but it may cause death if the disease spreads to the internal organs. It may also cause an infection.
