Research projects are fundamentally geopathological and histopathological investigation of tropical diseases in collaboration with other overseas or domestic institutions.
　　The pathology department is responsible for postmortem examinations and histological diagnostic pathology of surgical speciments including special research work on liver biopsy at the Nagasaki University Hospital.
　　In addition to the routine services mentioned above, the department is also responsible for lectures and practice for the undergraduate students at Nagasaki University School of Medicine on pathology of the hematopoietic system, liver, gallbaldder, biliary ducts and pancreas.
　　The postgraduate course of ordinary pathology, tropical pathology and liver pathology for graduate students of medicine is a four‐year program leading to Ph. D.
　　The five‐year professional pathologist program is offered, leading to the qualified pathologist of the Japanese Society of Pathology.
　　Facilities consist of histology, immunopathology and molecular pathology laboratories, and electron microscopy.
Present research projects are as follows:

１．Pathology of tropical diseases including infections, neoplasms, and other diseases.
２．Liver diseases in the tropics such as viral hepatitis, cirrhosis of the liver, hepatocellular carcinoma, and other endemic diseases.
