WebExtramedullary hematopoiesis (EMH) is often a physiologic response to ineffective marrow production of hematologic cells. While this can be found incidentally in … WebIn primary myelofibrosis, nucleated red blood cells (normoblasts) and myelocytes are released into the circulation (leukoerythroblastosis) when there is extramedullary hematopoiesis (ie, non-marrow organs have taken over blood cell production because of the fibrosed marrow). The serum lactate dehydrogenase level is often elevated.
