Bone and Soft Tissue Pathology Diagnostic and Prognostic Implications

Soft tissue and bone tumors are a heterogeneous group of tumors most often classified according to the type of tissue they most closely histologically resemble. Although sarcomas are rare, greater than 100 histologic subtypes of benign and malignant soft tissue and bone tumors are currently recognized. In this article, the authors review the current pathologic definitions, the classification and grading systems, supportive ancillary techniques, and the prognostic implications for some of the more common soft tissue and bone tumors.
