Abstract

Bone tumours arising from the coracoid process of the scapula are very rare. We present a case of a 19-year-old man with left shoulder pain for 1 year, with associated infraclavicular swelling for 8 months. Examination revealed a tender, bony, hard swelling measuring 3×4 cm. Imaging revealed an expansile osteolytic lesion arising from the coracoid process with loss of corticomedullary differentiation. MRI showed altered signal in the adjacent soft tissues. The patient underwent en bloc resection of the lesion. Histology was suggestive of osteoblastoma. At the end of 2 years follow-up, the patient had no pain or recurrence of the lesion. We present this case for its rare location and have briefly discussed the difficulties in diagnosis of this condition.
