What is cartilaginous benign tumors?

➢ Chondromas are benign tumors of hyaline cartilage that usually occur in bones of endochondral origin ➢ When They arise within the medullary cavity, they are called enchondroma ➢ When They arise on the cortical surface they are called juxtacortical chondroma. ➢ Diagnosis of enchondroma is usually made on standard radiography Biopsy is not necessary ➢ The rule is therapeutic abstention; ➢ Surgical treatment will be done if symptomatic or in case of suspected transformation into low-grade chondrosarcoma ➢ Enchondromas are true neoplasms, with mutations in the IDH1 and IDH2 genes. ➢ Solitary lesions are usually less than 3 cm in size and typically arise in metaphyseal regions of tubular bones, such as the distal femur here, but more likely in the hands and feet ➢ Cellularity is greater than that of normal cartilage, but the cells are not highly atypical
