👉 Bates' disease is a rare, autoimmune disorder characterized by chronic inflammation in the skin, affecting the skin, nails, and hair. It is caused by an immune response against the body's own cells or tissues, leading to tissue damage and scarring. The disease typically occurs in individuals who are genetically predisposed to it, such as those with genetic mutations that affect the immune system. Symptoms can include skin rashes, nail abnormalities, and hair loss.
