Pemphigus Vulgaris is a rare autoimmune disorder that causes painful blisters and sores on the skin and mucous membranes. It occurs when the immune system mistakenly attacks proteins that help skin cells stick together, leading to the separation of these cells and the formation of blisters. The condition often starts in the mouth and can spread to other areas, including the skin. Treatment typically involves medications that suppress the immune system, such as corticosteroids, to reduce inflammation and prevent new blisters from forming. Early diagnosis and management are crucial for improving outcomes.
