N. Paul Ohori, MD

Medical Director of Cytopathology


Dr. Ohori is a Professor of Pathology in the Division of Anatomic Pathology and Medical Director of Cytopathology at UPMC Presbyterian. He has been a faculty member in the School of Medicine since 1992 and has been involved in medical student, cytotechnology student, resident, and fellow training. He has been the chair of the curriculum committee of the residency program in the Department of Pathology, Board Member of the School of Cytotechnology, and the cytopathology representative to the Molecular Anatomic Pathology Division. From 2001 to 2008, he served as the Director for the Cytopathology Fellowship Program.

Dr. Ohori has provided service to the UPMC system since 1992 and over the last 15 years, he has served as the Medical Director of Cytopathology at UPMC Presbyterian Hospital. His service responsibilities have focused on Non-Gynecologic Cytopathology and Thoracic Surgical Pathology. In this regard, he provides consultative expertise in thyroid, head and neck, pulmonary, and gastrointestinal cytopathology. Dr. Ohori participates in a number of regional and national conferences in the areas of thyroid cytopathology and thoracic pathology.

Dr. Ohori has focused his efforts in clinically related research in Non-gynecologic Cytopathology. In general, his research involves three main areas:

  • Bridging the gap between cytopathology and surgical pathology by emphasizing correlation and understanding of organ specific concepts
  • Applying ancillary technologies to refine diagnostic and pathogenetic information
  • Quality improvement in cytopathology laboratory performance

Specifically, he has investigated the cytologic and molecular manifestations of thyroid, pancreaticobiliary and pulmonary neoplasms. Furthermore, he has been involved in improving cytopathology laboratory performance by developing a systematic method for cytologic-histologic correlation in non-gynecologic cytopathology.
