Diagnosis for Osteochondroma include Laboratory examinations and X-ray tests:
Laboratory examinations for Pathological changes:
1. The naked eye observation: mass 1 ~ 10cm, surface smooth, cartilage-like gray-blue, sections of cartilage cap thickness of less than 1cm.
2. Organizational form: the most superficial lesions thin fiber for the organizations, under the cartilage cap, small nuclear deep chondrocytes stained with the rules, and then down cartilage cell hypertrophy, calcification and the formation of sponge-like trabecular bone, trabecular bone between the red bone marrow and fatty marrow.
Osteochondroma is confirm diagnosed by X-ray tests. X-ray showed bone damage, from the metaphysis prominent, the general clinical see than smaller, because of the cartilage cap and non-imaging bursa synovialis, the bone image with the tumor site where the metaphysis of the bone structure of the same. The distinction is not easy. Tumor is located in long bones adjacent to the growth direction and the direction of muscle traction, such as distal femoral osteochondroma of the growth of the femur, tibia proximal to the distal tibial tumor growth. Different shape, can have a very long and narrow basal pedicle. Or very tubby base was broad, the larger expansion of the tumor such as its top cauliflower.
