title: A case of pericoronary pseudotumor due to localized Castleman's disease.
abstract: BACKGROUND
  A 59-year-old male had a latent epicardial mass discovered at cardiovascular imaging during the assessment of an aortic murmur.
  
  
  RESULTS
  The resected mass surrounded the left anterior descending coronary artery. It was a well-limited pericoronary cellular lesion. It was made of a mixture of polytypic plasma cells, lymphocytes with lymphoid follicles, hyaline vascular hyperplasia, and focal eosinophils. No immunoglobulin and TCR-gamma gene rearrangements were detected. In this immunocompetent patient, HHV-8 was negative.
  
  
  CONCLUSIONS
  The pattern was consistent with a pericoronary localized Castleman's disease of composite histologic subtype.
