Laboratory of Pathology: Training Programs

Hematopathology Fellowship

Blood cells

The Hematopathology Section of the Laboratory of Pathology, National Cancer Institute, offers a fully ACGME-accredited fellowship in hematopathology, which provides broad exposure to the diagnostic and investigative aspects of neoplastic hematopathology. Material is derived principally from an active in-house treatment program for both adult and pediatric hematologic malignancies. In addition, approximately over 2000 challenging cases are submitted in consultation each year. The Hematopathology Section collaborates with the Clinical Services of the NCI, NHLBI, and NIAID in both clinical management and research.

Participation in research is an intrinsic component of the fellowship program. Fellows have an opportunity to pursue laboratory interests related to experimental hematopathology and immunology. These investigations include the immunologic, functional, and molecular aspects of human leukemia and lymphoma. Appointments are for a period of 2 years, with extension available. In the first year, fellows focus primarily on clinical rotations, fulfilling the ACGME requirements to qualify for the board certification examination in hematopathology. In the second year, the majority of time is available for research.

The Hematopathology Section, under the leadership of Dr. Elaine S. Jaffe, provides a diagnostic service, which includes routine morphology, immunocytochemistry, flow cytometry, classical and research cytogenetics, and molecular genetics. The clinical rotations allow for exposure to these specialized diagnostic modalities. The facilities of the NCI Core Laboratories including Laser-capture microdissection, Microarray facilities, just to mention a few, provide access to the most modern molecular techniques.

Our program is integrated with the Hematology Department of the NIH Clinical Center, where fellows receive training in bone marrow pathology and laboratory hematology. Further exposure to laboratory hematology and bone marrow pathology is provided through elective rotations at George Washington University Hospital and Children’s National Medical Center. Enhanced exposure to hematopathology and flow cytometry is also obtained through an elective rotation at Johns Hopkins University Medical Center.


Candidates must have completed 3 years of training in anatomic pathology, or 4 years of training in anatomic and clinical pathology in a residency program accredited by the ACGME. Fellows must have a valid medical license in one of the 50 U.S. states, or Canada, at the time they begin their fellowship. Physicians who received their primary medical education outside the United States are eligible, as long as they meet other eligibility criteria. Prior research experience is highly desirable, as well as evidence of commitment to an academic career.
