What is Dedifferentiated Chondrosarcoma?Dedifferentiated Chondrosarcoma is a high-grade non-cartilaginous soft tissue tumour associated with the low-grade cartilaginous tumour. They account for almost 11% of all cartilaginous tumours of soft tissues and among rapidly metastatic tumours.
Disease EpidemiologyDedifferentiated chondrosarcoma usually occurs in the elderly, usually over 50. Localized pain (pain from where the tumour originates or has developed), edema, and paresthesias are common clinical manifestations. Paresthesia is a burning or tingling sensation in the affected area. In them, gross pathological changes are rarely observed. The most common sites of occurrence are the pelvis, thighs, proximal thigh, proximal humerus, distal thigh, and rib.
Disease Etiology (Causes)There is no exact- well-known cause.
