[Tumorous space occupying lesions of the scapula. An analysis of preoperative assessment of invasion]

Abstract

The radiographic and histological morphology of 38 tumors lesions of the scapula are analyzed. Osteochondromas (n = 12), chondrosarcomas (n = 7), plasmacytomas (n = 4) and Ewing's sarcomas (n = 3) were the most frequent neoplasms. The radiographically determined growth rates allowed an estimate of the dignity in all cases. Benign lesions were only observed in the first five decades of life, and were mostly located in the scapular blade. Most tumors found in the acromion and in the glenoid region and all lesions diagnosed in the 6th to the 8th decades of life were malignant. In 63.2% of cases correct diagnosis of the type of lesion present was possible on radiographic examination.
