[kon′drōsärkō′mə] pl. chondrosarcomas, chondrosarcomata
Etymology: Gk, chondros + sarx, flesh, oma, tumor
a malignant neoplasm of cartilaginous cells or their precursors that occurs most frequently in long bones, the pelvic girdle, and the scapula. The tumor is a large, smooth, lobulated growth composed of nodules of hyaline cartilage that may show slight to marked calcification. Also called chondroma sarcomatosum. chondrosarcomatous, adj.

Chondrosarcoma

chondrosarcoma

A malignant mesenchymal tumour caused by the uncontrolled proliferation of chondroblasts. It is the second most common primary malignancy of bone after osteosarcoma and represents 25% of such lesions.

Epidemiology
Arise in the axial and proximal skeleton of adults and older people.

Clinical findings
Often asyptomatic initially; later, pain for months to years, swelling.

Imaging
MRI is the modality of choice; CT, plain films, show destructive, aggressive permeation of diaphysis by tumour.
 
DiffDx
Metastatic carcinoma, enchondroma, chondromyxoid fibroma.

Types
Clear cell, de-differented, extraskeletal mesenchymal, juxtacortical, mesenchymal, myxoid.

Prognosis
Grade 1, 88% 5-year survival; grade 3, 40% 5-year survival.

chon·dro·sar·co·ma

(kon'drō-sahr-kō'mă)
A malignant neoplasm derived from cartilage cells.

chondrosarcoma

A rare malignant tumour of the cartilaginous parts of bone affecting mainly the pelvis, ribs and breastbone (sternum) and causes a slowly expanding swelling. The outlook after surgical removal is usually favourable.

chondrosarcoma

malignant neoplasm of cartilage, arising near ends of long bones, talus or calcaneum; presenting in older adults and only rarely in children; characterized by dull pain and swelling, bone matrix calcification, endosteal scalloping, local cortical thinning and expansion and soft-tissue involvement; difficult to diagnose from radiographs (see Table 1)
