title: Pathological study of primary cardiac and pericardial tumours in a specialist UK Centre: surgical and autopsy series.
abstract: BACKGROUND
  Primary cardiac and pericardial tumours are rare with a prevalence of between 0.001% and 0.3%. Thus, general pathologists are not familiar with them. Modern advances in cardiac imaging have increased the number of patients identified with a primary cardiac tumour in its early stage and also improved prognosis. At the Royal Brompton Hospital, London, we did a retrospective study to investigate the pathological features of primary cardiac and pericardial tumours and compared our findings to other cardiac centres.
  
  
  METHODS
  All pathologic records at the Royal Brompton Hospital between 1990 and 2008 were reviewed to identify patients with a confirmed diagnosis of primary cardiac tumours. A total of 94 patients with a histological diagnosis of primary cardiac and pericardial tumours were identified and formed the study population.
  
  
  RESULTS
  The majority (n=67, 71.3%) of cases were benign cardiac tumours. Myxoma was the most common histologic type accounting for 27 cases. Among cases with primary malignant tumours (n=27, 28.7%), unclassified sarcoma (n=11), leiomyosarcoma (n=5), and lymphoma (n=4) were the most common histologic types.
  
  
  CONCLUSIONS
  This study, primarily from an adult setting (n=78, 83%) demonstrates a large spectrum of cardiac tumours seen in recent cardiologic practice. Myxoma is still the most common tumour but more fibroelastomas are being diagnosed due to increased imaging.
