title: Extraskeletal chondrosarcoma. Report of 8 cases.
abstract: Eight cases of surgically and pathologically verified extraskeletal (soft tissue) chondrosarcoma were analyzed with regard to clinical and X-ray features. Their cardinal clinical aspects included presence of a local soft tissue mass and gradual enlargement of the mass accompanied by increasing pain. The X-ray signs were formation of a soft tissue mass, various forms of calcification in the central area of the tumor presence of saucer-like defect on the cortical surface of neighbouring bone in some cases, and bending deformity of the affected bone. The incidence and sites of predilection, the main X-ray findings, radiological diagnosis and differential diagnosis of the tumor were discussed.
