Osteochondroma of the scapula.

Osteochondromas are common primary bone tumors which are usually located in the distal femur. In a large retrospective study from the Mayo clinic, osteochondromas comprised 36% of benign bone tumors and nearly 10% of all bone tumors. While the scapula is rarely involved, this is the most common tumor of the scapula. Clinical signs of this lesion include shoulder pain and limited range of motion. Patients may present with winging of the scapula. Computed tomography is often necessary to fully define the location and character of the lesion. We present the case of a 14-year-old girl with pain and limited range of motion of the left shoulder. The diagnosis was that of osteochondroma of the scapula.
