Overview
If left untreated, patients with chondroma may progress to develop pain and discomfort. Common complications of chondroma include malignant transformation into a low grade chondrosarcoma, pathologic fractures and skeletal deformities
Natural History
If left untreated, patients with chondroma may progress to develop pain and discomfort. If an enchondroma is painful in the absence of a fracture, it should be considered malignant, unless proven otherwise.
Complications
Common complications of chondroma include:
- Malignant transformation into a low grade chondrosarcoma
- Sarcomatous changes in solitary enchondromas is rare. Risk is higher in Ollier's disease and Maffucci syndrome.
- Pathologic fractures
- Skeletal deformities
Prognosis
Prognosis is generally good for solitary chondromas and after surgical excision of
