The Department of Pathology & Immunology offers an accredited program in cytopathology with a robust and broad clinical cytopathology practice.


The cytopathology fellowship has received initial accreditation by the American Council for Graduate Medical Education (ACGME) on December 2, 1996. 


The fellow participates in a diverse fine needle aspiration biopsy service and is actively involved in providing on-site evaluation and superficial biopsies. There is a mixture of gynecological and non-gynecological cytopathology, reflecting a large academic medical center practice.

The application of routine and emerging ancillary testing is integrated into the practice. Dedicated time focused on laboratory management, specimen processing skills and research are provided.


Training for the fellowship occurs in state-of-the-art facilities at Washington University School of Medicine/ Barnes-Jewish Hospital. The cytopathology section is located in the 680,000-square-foot BJC Institute of Health (BJCIH) at Washington University School of Medicine, which is an 11-story research building housing laboratories and support facilities and is Washington University’s largest building.

The anatomic pathology clinical laboratories and offices are located on one floor. This close proximity makes it convenient and easy to interact with the laboratory, anatomic pathology faculty, residents and staff.


Applicants must have a MD or DO degree (or foreign equivalent with ECFMG certification) and 3 to 4 years of training in anatomic or anatomic and clinical pathology in an ACGME accredited program. Fellows must be board-certified or board-eligible in anatomic pathology. Applicants must be legally authorized to work in the United States.


Applicants must complete the online application and provide their CV, personal statement, photograph, USMLE scores (step 3 optional), and ECFMG certificate if applicable. The application portal will collect contact information for three individuals who will be asked to write letters of recommendation.
