Chondroma

Classification according to ICD-10
D16.9	Benign neoplasm of bone and articular cartilage unspecified (chondroma)
ICD-10 online (WHO version 2019)

According to the WHO definition, a chondroma (from the Greek chóndros = grain, piece, granule) is a benign tumor that forms mature cartilage tissue and has no signs of a chondrosarcoma in the tissue . Chondromas often occur on the hands, on the thighs and humerus and, rarely, on the cartilage braces 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 mature-cell cartilage tissue in the metaphyses of the long bones . Men and women are equally affected. Chondromas are located in the cortex ; if a tumor of the same type is medullary , it is called an en chondroma.

The chondroma is often a chance finding during an X-ray examination (e.g. after an accident). In some cases, the tumor can lead to pathological fractures . In the vast majority of cases, specific therapy is not necessary, and the risk of malignant degeneration is minimal with a single (solitary) finding. A check every one or two years is sufficient. If surgical therapy is necessary, this is usually done by clearing out the tumor and, if necessary, filling the defect with cancellous plastic . In terms of fine tissue, this tumor appears as a circumscribed lump of hyaline cartilage tissue ; it is difficult to distinguish it from the highly differentiated chondrosarcoma (malignant).
