[Usefulness of immunohistochemistry as a diagnostic tool for tumors and pseudotumoral bone lesions].
Immunohistochemical study for the diagnosis of bone tumors and tumor-like lesions has to be scheduled after an appropriate analysis of clinical data, radiological findings, and results of histology in H-E sections. The value of several markers for osteoblasts is discussed, chiefly for various forms of osteosarcomas. In the same way, the role of S-100 protein as well as anticollagen type II antibody is developed for cartilaginous tumors. The selection of markers in the fields of round cell tumors and spindle cell tumors of bone is also discussed. Some diagnostic problems with the support of immunohistochemistry are described, like chordomas versus chondrosarcomas or bone metastases. Lastly, immunohistochemical study of proliferating factors in the bone tumor field is quoted.
