Pemphigoid, also called sebaceous cyst, can easily become infected, and if an abscess is formed, it needs to be drained surgically in a timely manner, and if it occurs on the surface of the body, it usually improves gradually in about a week after surgery. After the surgery, the medication needs to be changed every day, and the abscess cavity should be thoroughly disinfected and cleared of pus moss and secretions, and then filled with dry gauze or iodoform gauze for adequate drainage. Postoperative anti-infection treatment is also needed, either oral broad-spectrum roxithromycin capsules or amoxicillin capsules, and local hygiene should be maintained during treatment. Pink tumor is a disease that occurs when the skin follicles and sebaceous glands do not empty smoothly and are prone to infection secondary to obstruction. In addition, underlying diseases such as diabetes are also prone to this disease.
