Normal Bone Marrow

Histological investigation of bone marrow biopsy is an integral examination method for diagnosis of various hematological and also non-hematological diseases [1]. Since sampling of bone marrow biopsies (BMB) from newborns as well as geriatric patients can easily be performed, the indications for retrieving BMB have increased, especially in hematology, internal medicine, oncology, but also osteology [2]. Various fixatives and different methods are described for preparation of bone marrow biopsy sections; however, each hematopathologist prefers his own technique used in his laboratory. Therefore, it is not our intention to persuade the investigating pathologists to use a special method, but the need for well-fixed and well-stained thin sections cannot be emphasized enough.
