RESUMEN
Tumors, which differentiate to cartilage, share characteristic features for the production of chondroid matrix by these tumor cells. The cartilage tumors are ranged from completely benign lesions to highly malignant. These are subdivided by location into peripheral, surface, central and intramedullary lesions. Benign bone tumors are a group of neoplasms that are most frequent in children and young adults, although they may also present in later stages of life. The malignant cartilage tumors affect bones and joints but rarely as compared to osteogentic tumors. The Malignant tumors cannot be differentiated from benign simply by biopsy without radiographic evidence. However, CT and MRI imaging may be of some use in defining the extent of tumour spread locally
