[Clinical-morphological aspects of osteochondroma of long bones].

Clinical-morphological aspects of osteochondroma reflect the rate of cancer growth and its prognosis. Verification of bones forms is required to diagnose exostosis. Revealed forms of osteochondroma differ by clinical course which need different surgical approach. The aim of the article was to propose new surgical technique to treat osteochondroma. 71 patients with osteochondroma were examined by clinical and radiological methods. The samples were investigated by histological, histostereometric, morphometric and immunohistochemical methods (using monoclonal antibodies ki-67). It is concluded, that the growth rate of exostosis depends on: location of the tumor; the structural architecture of the cartilage; enchondral ossifications in tumor. The active and passive stages of osteochondromas in long bones are depicted.
