School of Medicine - Clinical MedicineHematology and Immunology



We examine, treat and do research work for hematological disorders (for example, leukemia, lymphoma, and myeloma) and collagen-vascular disorders (for example, rheumatoid arthritis, systemic lupus erythematodes, Sjögren's syndrome, and vasculitis). We have been playing a central role in the study of IgG4-related disease in Japan. Furthermore, we are the research administration office for TAFRO syndrome, a rare and novel systemic inflammatory disease, with a grant from the Japanese Ministry of Health, Labour and Welfare.
