Bone marrow trephine interpretation: diagnostic utility and potential pitfalls.
Good quality paraffin-embedded sections can be obtained from bone marrow trephines, allowing the routine use of these biopsies in diagnostic histopathology. Trephines are superior to aspirates, especially for the assessment of marrow cellularity, the extent and pattern of tumour infiltration and the cell type. Bone marrow biopsies are useful in several areas, e.g. non-haematological disorders, myelodysplasia, the myeloproliferative group, lymphomas and leukaemias, which are briefly discussed below. Further advances in interpretation are likely with more frequent use of bone marrow trephines.
