A 43-year-old woman presented to the emergency department with substernal chest pain and dyspnea. After ruling out acute coronary syndrome or pulmonary embolus, a computed tomography scan of her thorax revealed lytic lesions of the sternum and second rib and a large mass involving the right scapula (Figure 1). On further inquiry, the patient acknowledged right shoulder pain that had been progressing over 5 months and leading to a limited mobility of the right upper extremity.
