title: Malignant fibrous histiocytoma of the pulmonary artery.
abstract: A patient is reported whose symptoms and clinical features were interpreted as pulmonary embolism. However, the ultimate diagnosis was malignant fibrous histiocytoma of the pulmonary artery, which was made evident at operation. Although extremely rare in the early medical literature, primary sarcoma of the pulmonary artery has been reported more frequently during the last decade. This patient may provide further insight into the clinical, diagnostic, and therapeutic features of primary sarcomas of the pulmonary artery.
