Surgical treatment of a primary cardiac lymphoma presenting with cardiac tamponade.

Primary cardiac lymphoma (PCL) is one of the rarest tumors and the most common type is large B-cell lymphoma. The right atrium and right ventricle are the most often involved, which should be diagnosed and treated in time. In this case, a female patient underwent an emergency surgical treatment for a large pericardial effusion and a huge mass in the right atrium. The huge mass was resected successfully. The pathological evaluation suggested that PCL and staging systemic chemotherapy were initiated according to the result, which significantly improve the prognosis of and quality of life.
