Tissues of 38 varieties of human skeletal tumors were studied by a complex of biochemical assays. It was found that such biochemical parameter as concentration of connective tissue components points to the degree of malignancy. The peculiarities of biochemical characteristics of skeletal tumors are of importance in differential diagnosis and may be used in the examination of tissue specimens obtained by biopsy or during surgery.

A case of a comparatively mild trauma of a lower extremity in an 11-year-old child complicated with deep thrombophlebitis of the thigh and pelvic bone, thromboembolism of the pulmonary artery branches, sepsis, and massive systemic fat embolism is described. The development of fat embolism in combination with thromboembolic complications in the absence of injuries of the skeleton and fat tissue may be explained from the standpoint of physico-chemical theory of pathogenesis of fat embolism. A close correlation between fat embolism and the system of blood coagulation was noted.
