The Hematopathology Fellowship Program at City of Hope is a two-year program primarily designed for fellows interested in academic hematopathology. Supporting one of the largest bone marrow transplantation programs in the United States, and enjoying an active consultation service, the program evaluates more than 3,000 diagnostic specimens involving peripheral blood, bone marrow, lymph nodes and extranodal biopsies each year. The program has a rich history, which includes notable past faculty such as Drs. Henry Rappaport, Daniel Arber and Lawrence Weiss. Multiparameter studies are emphasized, including analyses by morphology, immunohistochemistry, flow cytometry, and cytogenetic and molecular techniques, all supported by active in-house laboratories. 
The first fellowship year is Accreditation Council for Graduate Medical Education (ACGME)  accredited and focuses on diagnostic hematopathology. Didactic lectures, Pathology Grand Rounds, slide seminars, patient care conferences, bimonthly research meetings and a journal club are part of the educational experience. During the second year, fellows continue their research projects and participate as instructors in independent hematopathology case sign out within the division, preparing them for academic careers.
