【Fibrosarcoma of bone pathology - occurred in the outer membrane of soft tissue tumors were larger and the destruction of bone tissue later and less. Endometrial occurred in bone, the marrow of their average from top to bottom and around the development, so bone defects caused by the earlier and extensive, but not soft tissue tumors often significantly. Long bone or backbone of the metaphyseal bone may occur fibrosarcoma. The skull, jaw and spine of fibrosarcoma not uncommon, when a skull tumor, bone deformities inflammation may change. The naked eye observation that there is a false fibrous tumor cyst, section for the hard shiny white organizations, some of calcification may occur or tumor necrosis and a gray and white or yellow or false cyst-like. Soil under the microscope that its mast must organize the ingredients for nuclear staining deep spindle cells, in the minor constituents of the spacious circular or stellate cells, can be part of a transparent tumor tissue degeneration or mucus-like degeneration and necrosis and calcification phenomenon. The reaction of a very small amount of new bone biopsy occasionally can be found, but no bone tumors exist. There is a small part of the main organizations for the tumor shape, size, staining consistent with the small-vector form closely posed by the cell, fewer mitotic figures, called spindle cell sarcoma, it is of a fibrosarcoma of bone, no separate name the necessary. Overall, fibrosarcoma of bone is the main conditions; it occurred in the bone marrow or bone outer membrane, except for the soft tissue to be intrusive or violations of fibrosarcoma of bone tissue. Its main constituents and the general soft tissue fibrosarcoma exactly the same.
