[Pulmonary artery sarcoma mimicking a Hughes Stovin syndrome. Report of one case].

Pulmonary artery sarcoma is an uncommon entity with high mortality. Its clinical presentation is usually indistinguishable from pulmonary embolism, which leads to a significant delay in diagnosis. Hughes-Stovin syndrome is characterized by venous thrombosis and aneurysms of the pulmonary or bronchial artery. We report a 59 year-old female with a history of recurrent pulmonary embolism. In the last thromboembolic episode a pulmonary artery aneurysm was found on a CT scan. The patient was operated performing a left inferior lobectomy. The patient died five days after surgery and the pathological examination of the surgical piece revealed a pulmonary artery sarcoma.
