A 77-year-old man had progressive dyspnea with exertion and slight left anterior chest wall pain. He was later diagnosed with sarcomatoid carcinoma of the mandible and maxilla and treated with resection and adjuvant radiation therapy. Postoperatively, he developed worsening dyspnea and pericardial effusion with evidence of tamponade and died two months later. A pleural lesion was identified at autopsy (figures).
