Department of Diagnostic Pathology

Diagnosis in the department of pathology is done on the specimen from patients. We grossly and microscopically evaluate the specimen, and determine various points, such as whether the lesion is tumor or not, whether the tumor is malignant or benign, and whether the tumor cells are present in the cut end of surgically resected specimen. Because the diagnosis in our department is directly linked to the therapeutic strategy, the specialists certified by Japanese Society of Pathology do the diagnosis.


The number of diagnosis in surgical pathology is over 10,000 cases and the number of cytological diagnosis is over 12,000 cases per year. Conferences between pathology and clinical sections are held everyday, and the diagnosis with the tool of molecular pathology is also done.

Considerations in referring your patients to diagnostic pathology

Please feel free to refer your patients to our department. In the case of second-opinion, please contact the clinical sections first.
