An important case report on the Pulmonary artery sarcoma was published in the January-March 2008 issue of the journal.  I agree with the authors that the pulmonary artery sarcoma is a rare entity but in year 2008 itself, at least eleven articles could be found on medline. It is not true that these types of tumors are rare but their diagnosis may be confusing. There is no doubt that PET scan may prove to be beneficial but at the same time echocardiography may also help in detection of the tumor. Dyspnea may be the most common presenting symptom. Progressive dyspnea and weight loss may be important findings which should not be overlooked.  Proper physical examination findings were found to be lacking in this case. Heart rate, blood pressure, respiratory rate and presence of any cyanosis should have been explored properly.
The authors did not mention the size of the mass or any capsule covering it. These tumors involve the intimal surface of blood vessels, thereby obstructing the vessels or forming the emboli. The role of anticoagulant therapy is still being debated.  Overall, it is an interesting study and the authors and the journal need to be applauded for their role in publishing an interesting article.
