The classic text on the Mayo Clinic's experience with bone tumors, Dahlin's Bone Tumors presents a succinct, profusely illustrated summary of the largest single collection of well-diagnosed bone tumors anywhere in the world. This updated Sixth Edition contains a strong blend of archival material and new cases, and incorporates the latest knowledge about the grading and staging of these tumors. In the Sixth Edition, all gross anatomy photographs and photomicrographs are in full color—approximately 400 new full-color illustrations throughout the book. More attention is given to computed tomographic and magnetic resonance images. The book includes new information from recent clinicopathologic studies about radiographic and histologic variations in different tumor types, including chondroblastoma, osteoblastoma, and parosteal osteosarcoma. The section on neoplasm simulators has been expanded to include conditions, such as neuropathic joint, that may present as a neoplasm.
