title: The diagnostic utility of bone marrow trephine biopsies.
abstract: The bone marrow examination is invaluable in the diagnosis of certain haematological and non haematological conditions. The diagnosis of haematological disorders is achieved mainly by the examination of peripheral blood and bone marrow aspirate smears. Although bone marrow histology can provide additional information, for many technical reasons, trephines are not so popular and their diagnostic value is overlooked. Our experiences in the role of trephine biopsies in the diagnosis are presented in this article. All the bone marrow biopsies performed at the St. John's Medical College Hospital over the last 12 years (1990-2002) were reviewed The bone marrow biopsies were grouped into 3 categories for analysis. The trephine biopsy is invaluable in cases where the aspirate fails or is a dry tap as in the case of myelofibrosis, focal marrow involvement as in granulomatous lesions, metastatic tumour and lymphomas.
