Pemphigus Foliaceus is an autoimmune skin disorder characterized by the formation of blisters and sores on the skin. It occurs when the immune system mistakenly attacks proteins that help skin cells stick together, leading to the separation of skin layers. This condition primarily affects the outer layer of the skin, resulting in crusty lesions, often on the scalp, face, and chest. The exact cause of Pemphigus Foliaceus is not fully understood, but it can be triggered by factors such as certain medications or infections. Treatment typically involves immunosuppressive medications to reduce the immune response and promote healing of the skin.
