Ollier disease is a rare nonhereditary sporadic disorder where intraosseous benign cartilaginous tumors develop close to growth plate cartilage. Prevalence is estimated at around 1 in 100,000.[1]



Nominally, the disease consists of multiple enchondromas which usually develop in childhood. On radiographs, streaks of low density are seen projecting through the diaphyses into the epiphyses of the long bones, due to ectopic cartilage deposits. With age, the cartilage may calcify in the typical "snowflake" pattern. 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. One person in every 100,000 is affected. Ollier Disease is not normally diagnosed until toddler years because it is not very visible.

Associated conditions

Ollier Disease carries a high risk of skeletal, visceral and brain malignancy which occurs in approximately 25% of patients. Regular systemic screening is recommended.[2]


The disorder is named after French surgeon Louis Léopold Ollier (1830–1900).[3]

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.
