[Bone biopsy in hematology].

The importance of bone marrow biopsy in haematology lies in the fact that it puts relatively little stress on the patient and can reliably diagnose numerous blood diseases involving the bone marrow. It also provides information on the state of the bone marrow after treatment, and is essential for restaging in cases of lympho-proliferative diseases. A total of 116 personally conducted bone marrow biopsies proved to be a basic test for certain pathologies (medullary hypoplasia, myelofibrosis, N. H. lymphomas); while for others (leukaemia, plasmocytoma, polycythaemia), it was revealed to be a valuable back-up to clinical examination and other diagnostic procedures.
