Pulmonary artery sarcoma and chronic thromboembolism

Pulmonary artery sarcoma is a rare and highly lethal disease whose clinical findings are often indistinguishable from those of chronic thromboembolic pulmonary hypertension. Partial improvement after thrombolytic therapy has suggested that thromboembolic phenomena may be superimposed on the tumor, but, to date, a well-documented statement of these events has not been provided.
