Hematopathology Rotation

The hematopathology rotation is a broad-based experience in all aspects of clinical and anatomic hematopathology. The program emphasizes a clinicopathologic and integrated approach to bone-marrow and solid-tissue diagnostic hematopathology utilizing histology, immunohistochemistry, 10-color-flow cytometry, in situ hybridization, cytogenetic and molecular studies (gene-rearrangement and next-generation sequencing). The division also boasts a fellowship with enrichment of the resident's experiences by both fellow and faculty guidance and mentoring.

Case Mix

The 40-plus adult and pediatric hematologists/oncologists see a wide variety of neoplastic and non-neoplastic hematology cases from the outpatient community and the inpatient population.

Rotation Structure

There is a structured day allowing the residents to be involved in all aspects of the service, including daily interactions with clinicians. All bone marrow and lymphoma work-ups are reviewed at the multiheaded scope, increasing residents' exposure to the number and variety of cases. Residents can take advantage of a very large collection of interesting case slides and captured images from the department's archives. The hematopathology faculty has generated many systematic review materials for flow cytometry and histology for an efficient learning process.

There is a separate, one-month coagulation rotation where residents provide consultations on coagulopathies and hemoglobinopathies (see separate coagulation rotation description).
