Chondroid and Osseous Tumors of Soft Tissue

Cartilage and bone formation may be found in several types of soft tissue tumor, either as a metaplastic phenomenon or as a neoplastic component of some sarcomas. Metaplastic (benign) osteochondroid change may occur in hamartomas; benign neoplasms such as lipoma, fibromatosis, and calcifying aponeurotic fibroma; and the stroma in malignant soft tissue tumors, including liposarcoma, synovial sarcoma, low-grade fibromyxoid sarcoma, and sclerosing epithelioid fibrosarcoma. Malignant cartilage or bone formation also may occur by divergent differentiation or as heterologous mesenchymal elements in müllerian and other carcinosarcomas, mesotheliomas, malignant peripheral nerve sheath tumors, and dedifferentiated liposarcomas.
