Osteoid osteoma of the scapula is a rare benign lesion. This is a case report of a subchondral osteoid osteoma that involved the anterior rim of glenoid. Surgical approach in this atypical area may seem difficult. The excision of the lesion and grafting was performed by a deltopectoral approach. One year after the surgery, the patient remains pain free and has full range of motion with no recurrence of the tumour.
