Thoughts on the diagnosis of bone tumors.

The pathologist and the radiologist have each been given reason to believe that he is capable of accurately diagnosing bone tumors without the assistance of the other. However, each specialist has recourse to tools and procedures not available to the other, and their findings should be considered as complementary. Although there are radiographic features which could be an indication of malignancy, there are too many common exceptions to formulate a general rule. Likewise, although the pathologist can examine microscopic morphology and obtain biochemical information using special stains, the sample being examined may not be representative of the entire tumor. Thus the ultimate benefit to the patient can be obtained only if the radiologist and pathologist work in concert with one another and with the surgeon toward the common goals of accurate diagnosis and prompt, appropriate management of bone tumors.
