Ollier Disease is a rare genetic disorder characterized by the development of multiple benign tumors called enchondromas in the bones. These tumors typically form in the long bones, such as the arms and legs, and can lead to bone deformities and fractures. The condition is caused by mutations in the IDH1 or IDH2 genes, which are involved in cellular metabolism. Individuals with Ollier Disease may experience varying degrees of symptoms, including pain and swelling in affected areas. While the tumors are usually non-cancerous, there is an increased risk of developing chondrosarcoma, a type of bone cancer, in some patients. Regular monitoring and medical management are essential for those diagnosed with this condition.
