Chondroma

As chondroma (from Greek Chondros = grain, piece, grain ) is called the WHO definition in a benign tumor that mature cartilage tissue and cellular level has shown no signs of chondrosarcoma. Chondromas often occur on the hands, on the thigh and upper arm bone and rarely to the cartilage rings of the bronchi.

The chondroma is the second most common benign cartilage-forming tumor and occurs more frequently in the 2nd to 4th decade of life. It typically forms reifzelliges cartilage in the metaphyses of long bones. Men and women are equally affected. Chondroma located in the cortex, sits a similar medullary tumor, it is called a enchondroma.

The chondroma is often an incidental finding in the context of X-ray examination (eg after an accident). In some cases, the tumor can lead to pathological fractures. No specific therapy is in most cases not necessary, the risk of malignancy in an individual ( solitary ) finding minimal. A control in one-or two-year intervals is sufficient. Should surgical treatment be necessary, this is done usually by removal of the tumor and if necessary fill the resulting defect bone grafting medium. Histologically, this tumor as impressed circumscribed nodes of hyaline cartilage tissue, the differentiation from highly differentiated chondrosarcoma ( malignant) is difficult.
