Primary cardiac lymphoma initially diagnosed by routine cytology. Case report and literature review.
A case of primary cardiac lymphoma initially diagnosed by routine cytologic examination of pericardial fluid is presented. In a 64-year-old woman woman who originally presented with chest pain and heart block, the initial clinical impression was ischemic heart disease. However, coronary angiography failed to reveal significant disease. An echocardiogram demonstrated pericardial fluid, which was drained. A small amount was sent for cytologic examination, and the diagnosis of malignant lymphoma, large cell type, was made. Subsequent radiologic examinations revealed an intracardiac mass involving the atrioventricular canal; surgical biopsy confirmed the diagnosis of a large cell lymphoma. While primary malignant lymphoma of the heart is rare, this case highlights the efficacy of routine cytologic examination of an effusion fluid (often drained therapeutically) in establishing the correct diagnosis.
