Primary leiomyosarcoma of bone. An immunohistochemical and ultrastructural study. Archives of pathology & laboratory medicine, 1983, Volume: 107, Issue:8 Primary leiomyosarcoma of bone is extremely rare. A 60-year-old woman had a mass in the right femur that was studied immunohistochemically and by electron microscopy. Human smooth-muscle actomyosin was detected in tumor cells, but human skeletal-muscle myoglobin and lysozyme (muramidase) were not. Electron microscopy of the tumor showed findings suggestive of a smooth-muscle origin, such as myofilaments, dense bodies, pinocytotic vesicles, and basement membrane. The results were diagnostic of leiomyosarcoma rather than rhabdomyosarcoma, fibrosarcoma, or malignant fibrous histiocytoma, which are similar neoplasms. We believe that ours is the first case of primary leiomyosarcoma of the bone proved by immunohistochemistry.

[Concentration of lysozyme during mineralization in callous tissue of healing fractures (author's transl)]. Langenbecks Archiv fur Chirurgie, 1978, Oct-16, Volume: 346, Issue:3 Investigations have suggested that lysozyme (E.C. 3.2.1.17) is involved in bone mineralization. High concentrations of lysozyme is found in the growth plate near cartilage bone junction, where it is located at the collagen fibrils and in the ground substance. Quantitative studies of lysozyme levels were made in ossifying tissue of healing fractures, to confirm the existence of this relationship on bone repair. Callous tissue, serum samples and normal bone was collected from 42 rats at 15 intervalls during a 50 day healing period. Agar gel diffusion test was used for quantitation of lysozyme. Electrophoresis of tissue extract and standard henn egg white lysozyme served as control. Lysozyme levels in callous tissue increased significantly (4--5-fold) from 4.--21. day p. trauma and subsequently decreased. The concentration in serum samples did not change significantly. Changes in Ca concentration and histological studies during tests confirm a direct relationship between bone mineralization and lysozyme level changes.
