An Unusual Presentation of Osteochondroma on the Dorsal Surface of the Scapula: A Review of Two Patients

INTRODUCTION: Osteochondroma of the scapula is a rare tumour of the thorax. It constitutes 14.4% of all tumours of the scapula with the ventral surface being the most common site of presentation. The dorsal surface of the scapula is rarely seen as a potential site for the origin of osteochondroma from our review of the literature, which was the case in our patient. Most of the patients presenting with osteochondroma on the dorsal aspect of scapula have been reported to be of the sessile variant. CASE REPORT: We report two rare cases of a pedunculated variety of osteochondroma at an unusual site-dorsal surface of the scapula in a 19-year-old male and a 5-year-old male child. The tumours were excised and the diagnosis was confirmed by histopathological studies. CONCLUSION: This case series is reported for its rarity and its unusual site of presentation. A solitary congenital variant of osteochondroma of the scapula has never been reported to the best of our knowledge.
