[Radiological and histomorphological correlation of bone tumors and tumor-like diseases (author's transl)].

In the diagnosis of bone tumors and tumor-like lesions the radiographic examination plays a dominant role in the phase before performing a biopsy, with the support of this examination important facts are available for the further diagnostic procedure, for planning the biopsy and also for getting the preliminary guiding principles how the therapy has to be performed. In order to interpret a radiograph of a diseased bone optimally it is necessary to know the histomorphological background of an X-ray feature. This more particularly as the reaction of bone to a pathological process is limited to only 2 radiographic images: osteolysis or/and osteosclerosis. On the basis of the histological pattern and the dynamic micromorphological process the picture of osteolysis and osteosclerosis is analysed. The periosteal reaction is also considered in this manner. After the representation of these general principles a detailed tabulated synopsis is given about the correlation between the histological and roentgenological findings of all benign and malignant bone tumors and tumor-like conditions.
