Osteochondroma of the ventral scapula causing scapular static winging and secondary rib erosion.

An osteochondroma is a benign tumour of bone, which is located mainly in the metaphysis of long bones. It does not commonly occur in the scapula. On the ventral surface of the scapula, it can produce various manifestations due to mass effect. We are reporting a rare presentation of an osteochondroma at superomedial angle of ventral aspect of the scapula in a 31-year-old female. She initially presented with a painful shoulder and radiating pain in the arm. The scapular mass produced pseudo winging of the scapula and erosion of the ribs on the same side. The patient was successfully managed by open excision, using a parascapular approach. The patient had no evidence of recurrence at one year's follow-up and is currently able to carry on her day to day activities without any discomfort.
