What is Ollier’s disease (enchondromatosis)?

Ollier’s disease which is also known as enchondromatosis, is a rare non-hereditary disorder which is characterized by the presence of multiple enchondromas, which are benign cartilage tumors within the bones. This condition primarily affects the long bones, such as the arms and legs, and may lead to skeletal deformities and functional impairments. Let’s look into the details of the disease, covering it’s causes, symptoms, diagnosis, treatment options, and some frequently asked questions about this particular disease.

Causes Of Ollier’s Disease

The exact cause of Ollier’s disease remains unknown, and it is not typically inherited. Most cases arise sporadically, with no apparent genetic link. The development of enchondromas is thought to be related to somatic mutations occurring during early bone development.

Somatic mutations are alterations in the DNA of cells that occur after conception and are not passed on to the offspring. Unlike germline mutations, which are inherited and present in every cell of an individual’s body, somatic mutations are specific to certain cells and arise during an individual’s lifetime.


The main symptom of Ollier’s disease is the presence of multiple enchondromas, which can lead to various clinical manifestations. Patients may experience bone pain, deformities, and limb length discrepancies. How severe it can be and the type of symptoms vary widely among individuals.


Diagnosing Ollier’s disease involves a combination of clinical evaluation, imaging studies, and, in some cases, a biopsy. X-rays and MRI scans are commonly used to visualize the enchondromas and assess their impact on bone structure. A biopsy may be performed to confirm the nature of the tumors.

Treatment Options

The management of this disease is primarily focused on addressing symptoms and preventing complications. Surgical intervention may be considered for symptomatic enchondromas causing pain, deformity, or functional impairment. However, complete removal of all tumors is often challenging due to their multifocal nature.


The prognosis for individuals with this disease varies depending on the extent and severity of skeletal involvement. While some people may experience minimal symptoms and lead relatively normal lives, others may face significant challenges due to deformities and associated complications.

Frequently Asked Questions

Is Ollier’s disease hereditary?

No, the disease is typically not hereditary. Most cases occur sporadically, and there is usually no family history of the condition.

How is Ollier’s disease diagnosed?

Diagnosis involves a combination of clinical evaluation, imaging studies (X-rays, MRI), and, in some cases, a biopsy to confirm the presence of enchondromas.

What are the common symptoms of Ollier’s disease?

Common symptoms include bone pain, deformities, and limb length discrepancies. The severity of symptoms varies among individuals.

Can Ollier’s disease be cured?

There is no cure for this disease. Treatment aims to manage symptoms and may include surgical intervention for symptomatic enchondromas.

Is Ollier’s disease a form of cancer?

No, the disease is not a form of cancer. Enchondromas are benign tumors, but in some cases, they may transform into a more aggressive form called chondrosarcoma.

What is the long-term outlook for individuals with Ollier’s disease?

The long-term outlook varies. Some individuals may lead relatively normal lives, while others may face challenges due to skeletal deformities and associated complications.

Can Ollier’s disease be prevented?

As the exact cause is unknown, there are no specific preventive measures for this disease. Early diagnosis and management are the key to addressing symptoms and preventing complications.


This disease is a rare disorder characterized by multiple benign cartilage tumors within the bones. While there is no cure, proper diagnosis and management can help improve the quality of life for individuals affected by this condition. If you suspect Ollier’s disease or have concerns about bone health, consulting with a healthcare professional is important for accurate diagnosis and appropriate treatment.
