The Department of Dermatology specializes in all diseases affecting the skin.

Medical services

In the outpatient clinic, six physicians provide medical care for new and follow-up patients. Specialized outpatient services are also provided. In the inpatient ward, supervising physicians and interns work in pairs as the attending physicians for one patient. The treatment for each patient is discussed among staff members during ward rounds. When appropriate, the attending physicians continue to observe the clinical course of patients after hospital discharge.

Diagnosis and treatment policy

After making a diagnosis based on visual inspection, bacterial and /or fungal culture tests and, if necessary, skin biopsies are conducted. If a diagnosis can be established histologically (and immunohistologically), various external and internal drug applications, ultraviolet therapy, and surgical treatments are used alone or in combination. If necessary, the patient is hospitalized for various examinations and treatment.


The outpatient clinic provides treatment in specialized therapeutic areas including atopic dermatitis, psoriasis, scleroderma/connective tissue disease, bulluous disease, dermatologic surgery, lymphoma, laser surgery, etc.

Target diseases

Skin tumors, collagen disease, skin infection, nevus/phakomatosis, keratosis/ inflammatory keratosis (including psoriasis), eczema/dermatitis (including atopic dermatitis), physical/chemical injuries, intoxication dermatosis, erythema, etc.

Advanced treatments/ Specialized treatments

Ultraviolet irradiation

Patients with psoriasis, parapsoriasis, and mycosis fungoides are generally hospitalized for narrow band UVB therapy.


New drugs to target specific parts of the immune system, are used to treat psoriasis.

Laser irradiation

Laser irradiation is currently only applied to the treatment of diseases that are covered by national health insurance. Pulse dye laser is used to treat hemangioma simplex, strawberry hemangioma, and capillary telangiectasia; and Q-switched Alexandrite laser is used to treat Ota’s nevus, ectopic Monqolian spot, and traumatic tattoos.

Frequently performed tests


Microscopy, dermatoscopy, patch test, biopsy, skin ultrasound examination


Light-exposure test, patch test, oral administration test, biopsy, skin ultrasound examination.
