Diagnostic Pathology

羽賀先生顔写真 Hironori Haga, M.D., Professor  btn

Diagnostic pathology is a clinical application of traditional anatomic pathology, contributing to determination of treatment strategy and evaluation of effects of treatment. Our department started as Laboratory of Anatomic Pathology in 1980, and has long been recognized as a branch laboratory of investigative pathology and clinical pathology. It is now responsible for all histopathological diagnosis of surgical specimens and autopsies in University Hospital as well as education of systemic pathology for undergraduate students.

Research and Education

Most of our researches are clinically oriented, and our goal is to provide accurate and scientific diagnosis based on histology and cytology.
Current research fields include 1) transplant pathology, 2) lung cancer, and 3) mast cell disorders. In transplant pathology, antibody-mediated rejection of the liver allografts has been our main interest. For lung cancer, we demonstrated that new WHO classification is closely related to genetic changes and patients’ prognosis. We also clarified that CD158d, also known as NK cell-specific receptor, has several functions in mast cells.
Education for graduate students is combination of research and advanced training for diagnostic pathology. Subspecialty training for surgical pathology is encouraged in combination with basic investigative research and/or clinic-pathologic study using immunohistochemistry and in situ hybridization. For research, in-house pathology diagnosis database, image analysis using virtual microcopy, and tissue microarray technique are also available.
