Ollier disease

Ollier disease is a rare nonhereditary sporadic disorder where intraosseous benign cartilaginous tumors (enchondroma) develop close to growth plate cartilage. Prevalence is estimated at around 1 in 100,000.X-ray showing calcified enchondromas localized in finger a 37-year-old patient affected with Ollier diseaseX-ray showing enchondromas localized in the humerus of a 37-year-old patient affected with Ollier diseaseX-ray showing enchondromas localized in the lower part of the radius of a 37-year-old patient affected with Ollier diseaseMRI showing enchondromas localized in the lower part of the radius of a 37-year-old patient affected with Ollier diseaseMRI showing enchondromas localized in the lower part of the radius of a 37-year-old patient affected with Ollier disease.Enchondromas localized in the upper part of the humerus of the same patient Ollier disease is a rare nonhereditary sporadic disorder where intraosseous benign cartilaginous tumors (enchondroma) develop close to growth plate cartilage. Prevalence is estimated at around 1 in 100,000. Nominally, the disease consists of multiple enchondromas which usually develop in childhood. The growth of these enchondromas usually stops after skeletal maturation. The affected extremity is shortened (asymmetric dwarfism) and sometimes bowed due to epiphyseal fusion anomalies. Persons with Ollier disease are prone to breaking bones and normally have swollen, aching limbs. Ollier disease carries a high risk of skeletal, visceral and brain malignancy which occurs in approximately 25% of patients. Juvenile granulosa cell tumour has been associated with the disease. The incidence of secondary chondrosarcoma in Ollier disease is not known, but may be as high as 25%, pelvis and shoulder girdle being the commonest locations. A related disorder called Maffucci syndrome named after Angelo Maffucci is characterized by enchondromas associated with multiple hemangiomas which usually occur in the hands and feet. Maffucci syndrome carries a higher risk for cancer.
