Ultrasound and computed tomography (CT) guided percutaneous needle biopsy of soft tissue lesions was performed in 39 patients. A correct diagnosis was obtained in 35 of 42 biopsies, with an overall accuracy rate of 83 %. No false-positive diagnoses were obtained, and no complications related to the

✦ Synopsis
Computed tomography was used to identify three different ways in which primary bone tumors may transgress a bony cortex. Analysis of the pattern of cortical transgression was used in conjunction with the presence or absence of matrix mineralization to classify correctly the lesion into one of four different diagnostic categories in 84% of 72 cases. These data demonstrate that certain types of behavior characterize the lesions under discussion and that this information may be helpful in diagnosis.

## Abstract Samples from 48 benign and 102 malignant bone and soft‐tissue tumors were analyzed cytogenetically and by DNA flow cytometry. Clonal chromosome abnormalities were found in 82 tumors and normal karyotypes in 68; 61 tumors were DNA‐non‐diploid and 89 were diploid. The cytogenetically abno
