In large, secondary chondrosarcoma arises at the site of osteochondroma due to increased thickness of the cartilage cap indicating potential malignant transformation. It is characterized by the presence of multinucleated giant cells (osteoclast-like cells).Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases.

There may be a lump, pain, or neurological signs from pressure. They stem from ICD-O second edition Soft tissue sarcomas are rare neoplasms with over 150 different histological subtypes or forms. This classification is widely used by cancer registries.. Characteristic features of this tumor include the vascular axes within the tumor, which make the distinction with normal hyaline cartilage. It is characterized by the presence of multinucleated giant cells (osteoclast-like cells).Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases. Rhabdomyosarcoma (RMS) is a highly aggressive form of cancer that develops from mesenchymal cells that have failed to fully differentiate into myocytes of skeletal muscle.Cells of the tumor are identified as rhabdomyoblasts.. A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas.About 30% of bone sarcomas are chondrosarcomas. It is currently in its third revision (ICD-O-3). It is thought to arise from an outgrowth of immature cartilage cells (chondroblasts) from secondary ossification centers, originating from the epiphyseal plate or some remnant of it.. Chondroblastoma is very uncommon, accounting for only 12% of Chondrosarcoma; 171 Malignant neoplasm of connective and other soft tissue.

A sarcoma is a malignant tumor, a type of cancer that arises from transformed cells of mesenchymal (connective tissue) origin. When the bone tumor grows on other bone it is known as "homoplastic osteoma"; when it grows on other tissue it is called "heteroplastic osteoma".
