To see the skin is mainly registered with dermatology. Some of the different diseases have skin manifestations but also involve many other related departments, such as lupus erythematosus, which has a skin rash but the patient also has systemic involvement. For example, if there are kidney problems or heart problems, the patient can be registered with rheumatology, and if cosmetic problems or removal of body swellings are involved, the patient can be registered with dermatology or plastic surgery. Patients who have allergic skin disease manifestations, as well as conjunctivitis or asthma, can also be registered with the Department of Allergology. Some patients whose conditions cannot be distinguished well can directly register with the dermatology department, and the dermatologist will screen them and solve them in the dermatology department if they can be solved in the dermatology department, and if the dermatologist cannot solve them, he will suggest to register with the relevant department.
