First, working definitions of the terms differentiated, undifferentiated, and dedifferentiated are developed. It measured 14 x 8 x 6 cm and included bone (remnant of sacrum), nerve trunks (roots of lumbosacral plexus), and adherent portion of gluteal muscles. Epidemiology Demographics Primary central chondrosarcoma is defined by the formation of hyaline cartilage with decreasing matrix production in higher grades and constitutes about 80% of all chondrosarcomas [].Dedifferentiated chondrosarcoma is characterized by a low-, or intermediate grade chondrosarcoma juxtaposed to a . It is in the chondro-osseous grouping of tumours and can be lumped into the much large category of the soft tissue lesions . Dedifferentiated chondrosarcoma was first proposed in 1971 by Dahlin and Beabout. The imaging presentations are primarily of common central chondrosarcoma, combined with cortical destruction, soft tissue mass, and pathological fractures. Dedifferentiated chondrosarcoma (DCS) is a rare and aggressive malignancy with a poor prognosis. Mutations in SUZ12 or EED, which encode polycomb repressive complex 2 (PRC2). Dedifferentiated liposarcoma is a high-grade nonlipogenic sarcoma that arises in a background of a preexisting well-differentiated liposarcoma. Which options are best for you depends on where your cancer is located, how quickly it's growing, whether it has grown to involve other structures, your overall health and your preferences. Dedifferentiated chondrosarcoma (DDCS) accounts for 10% of all chondrosarcomas and has the poorest outcome, with a 5-year survival rate of 7%-25%. However, rare cases have minimal (<1 cm) or small (1-2 cm) areas of DD. The differential diagnosis of malignant hamartoma was discussed.

Work from our laboratories has demonstrated some of the protective and anti-inflammatory effects of curcumin using biochemical and morphological techniques. A dedifferentiated chondrosarcoma is a combined tumor made up of two components which are often sharply demarcated from one another (thus raising the possibility of it representing a collision tumor). Tumor biphasism is the norm. The latest edition of the WHO Classification of Tumours of Soft Tissue and Bone is a comprehensive, yet concise reference book. Skeletal Radiol 15:77-81,1986. . Curcumin was also shown to suppress TNF--induced MMP-13 expression in primary chondrocytes and SW1353 chondrosarcoma cells [135]. Based on the morphologic feature alone, a correct diangosis of CHS may be difficult, Therefore, correlation of radiological and clinicopathological features is mandatory in the diagnosis of CHS. Site - Axial skeleton (more aggressive), medullary cavity of femur, humerus, ribs and rarely digits. Chondrosarcoma represents a heterogeneous group of tumors. The purpose of this investigation was to describe our treatment and outcomes of 16 DCS patients at our institution and provide a review of the current literature. Other treatments might be recommended in certain situations. The behavior of these lesions ranges from slowly growing, nonmetastasizing tumors to very aggressive metastasizing sarcomas. Dedifferentiated chondrosarcoma from the femoral resection; second local relapse.
