WebIntroduction. Extramedullary hematopoiesis (EMH) is defined as the production of normal blood cells outside of the bone marrow. 1,2 It is a compensatory mechanism that is closely related to inadequate functioning of medullary hematopoiesis, especially myeloproliferative disorders and hemolytic anemia. 1,3 However, there have also been reports of EMH in … In adults, the majority of hematopoiesis occurs in the bone marrow. Significant production in any other organ is usually the result of a pathological process.
