Extramedullary Hematopoiesis . This is the term used for blood cell production that occurs outside of the bone marrow. It can be seen in chronic anemia, with the production of blood cells in the liver, spleen and sometimes in the lymph nodes. In other scenarios, there may be malignant hematopoietic cells located in areas outside of the bone marrow.
