Primary cardiac angiosarcoma: A diagnostic challenge in a young man with recurrent pericardial effusions.

Cardiac angiosarcomas are rare, rapidly progressive tumours that often present as diagnostic dilemmas resulting in delayed diagnosis. They should be considered in patients with recurrent pericardial effusions.A 33-year-old man presented for evaluation of a recurrent pericardial effusion. Infectious and rheumatological workups were negative. Pericardial fluid cytology and pericardial biopsy were unremarkable. Imaging, including echocardiogram and magnetic resonance imaging, were nondiagnostic.While awaiting surgical intervention, the patient developed respiratory failure requiring urgent intubation. Intraoperatively, he experienced significant hemorrhage from the myocardium. Hemostasis could not be achieved and the patient expired. Pathology reports revealed metastatic angiosarcoma.The present case illustrates a rare case of primary cardiac angiosarcoma posing a diagnostic dilemma in a young man. The authors present the challenges in diagnosis, and review the most current diagnostic and therapeutic strategies in the care of patients with this condition.
