This comprehensive, superbly illustrated reference is designed to provide practical diagnostic assistance for hematopathologists when dealing with common and uncommon lesions in bone marrow trephine biopsies (BMTBs). At the heart of the book is a systematic analysis of neoplastic hematological and non-hematological disease entities, with concise identification of the key features of myeloproliferative neoplasms, myelodysplastic syndromes, acute and chronic leukemias,   eosinophilia-associated myeloid/lymphoid neoplasms, lymphoproliferative disorders, and selected non-hematopoietic  malignancies. Relevant examples of BMTBs are presented, with microscopic description, high-quality photomicrographs, and clinical data. The book also explains how to assess hematopoietic and stromal components of normal BMTBs, identifies the heterogeneous patterns that may be observed in healthy individuals, and analyzes reactive conditions, with particular attention to diagnostic problems andpitfalls.
