👉 Koning'sberger's disease, also known as hemangioma, is a rare but serious type of skin cancer that occurs in the epidermis (top layer) of the skin. It typically affects the face, neck, and scalp, and can cause severe pain or swelling if left untreated. The treatment for Koning'sberger's involves surgery to remove the tumor, which may involve radiation therapy. While this condition is not curable, it is treatable with chemotherapy and radiation therapy.
