Hematopathology

Hematopathology is the branch of pathology which studies diseases of hematopoietic cells (see below). In the United States, hematopathology is a board certified subspecialty (American Board of Pathology) practiced by those physicians who have completed general pathology residency (anatomic, clinical, or combined) and additional fellowship training in hematology.

Hematopoietic cells originate from the bone marrow and contribute the cellular components of blood including red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (megakaryocyte-derived bodies). Additionally, leukocytes contribute significantly to the cellular composition of lymph nodes, the spleen, the thymus, and mucosa associated lymphoid tissues, and are present to some degree in all tissues. Diseases of the hematopoietic system generally manifest as decreases (anemia) or increases (lymphoma/leukemia) in these cell types. Consequently, hematopathologists most frequently evaluate peripheral blood smears, bone marrow aspirates and biopsies, and lymph nodes biopsies to determine the nature of hematopoietic disease. The hematopathologist incorporates traditional microscopy with ancillary techniques including general laboratory values, immunohistochemistry, flow cytometry, and molecular diagnostic tests to make the most accurate diagnosis. The hematopathologist works closely with the hematologist/oncologist specialty doctor who sees the patient and decides on the best treatment based upon the diagnosis made by the hematopathologist.
