Ollier disease is a rare genetic disorder characterized by the development of multiple enchondromas. The clinical manifestations of the disease vary widely, but patients often present with bone deformities and an increased risk of developing chondrosarcoma. Here, the authors present a case report of a 25-year-old male patient with a devastating and historic evolution of Ollier disease., Case Presentation: At the age of 10, the patient developed a sub-centimeter mass in the first phalanx of the left middle finger, which subsequently grew in size. A biopsy was performed at the age of 14, which confirmed the diagnosis of chondroma. At the age of 14, the patient developed multiple large masses on the left hand, resulting in the amputation of his left hand. At 25 years old, the patient developed new masses in his contralateral hand and left foot., Discussion: Ollier disease is caused by somatic mutations in the PTH/PTHrP receptor gene, leading to the formation of multiple enchondromas. Patients with Ollier disease are at an increased risk of developing chondrosarcoma, which can be life-threatening. The diagnosis of Ollier disease is usually made based on clinical and radiographic findings, and genetic testing can confirm the diagnosis. Treatment is typically focused on managing the symptoms and preventing the development of chondrosarcoma., Conclusion: The authors presented a case report of a patient with a devastating and historic evolution of Ollier disease. This case highlights the importance of early diagnosis and management of this disease to prevent the development of chondrosarcoma and minimize the risk of complications. Further research is needed to better understand the underlying mechanisms of the disease and develop effective treatments., Competing Interests: None., (Copyright © 2023 The Author(s).
