Case Series - Osteochondromas at Rare Locations

Gireesh Khodnapur et al. J Orthop Case Rep. 2023 Jan.

Abstract

Introduction: Osteochondromas are very common. They are typically seen in long bones and rarely seen in smaller bones. Some of the rare presentations include flat bones, the body of pelvis, scapula, skull, and small bones of the hand and foot. Their presentation also varies according to the site of presentation.

Case report: We have included five cases of osteochondromas occurring at rare locations with variable presentations and their management. We have included one case of metacarpal, one case of skull exostosis, two cases of scapula exostosis, and one case of fibula exostosis.

Conclusion: Osteochondromas can rarely occur at unusual locations. It is important to thoroughly evaluate all patients presenting with swelling and pain over bony regions to accurately diagnose osteochondromas and manage accordingly.

Keywords: Scapula; excision; fibula; metacarpal; skull.
