Abstract
A 60‐year‐old man presented with a 3‐month history of shortness of breath. He was found to have a right thoracic mass involving the right middle and lower lobes, pulmonary hilum, and mediastinum. Diagnosis could not be established by pleural fluid cytology, pleural biopsies, bronchoscopy, and ultrasound‐guided needle biopsies. A diagnostic exploratory thoracotomy was performed. Massive hemorrhage was encountered upon opening the pleura, and bleeding was controlled by performing a radical pneumonectomy. Histology revealed angiosarcoma, pulmonary primary. The patient survived for 68 days. At autopsy, he was found to have adenocarcinoma of the prostate, adenocarcinoma of the rectum, carcinoid of the ileum, and leiomyoblastoma of the stomach as well as diffuse metastases from the angiosarcoma. This represents the fourth reported case of primary pulmonary angiosarcoma.
