title: Left atrial primary B cell lymphoma presenting with mitral regurgitation.
abstract: Primary cardiac lymphoma (PCL) is an extremely rare diagnosis. We present a case of a 38-year-old immunocompetent female who presented with dyspnea on exertion and chest pain and the echocardiography revealed a mass in the left atrium (LA) causing moderate mitral regurgitation and mimicking a left atrial myxoma. The patient was managed with excision of the mass and mitral valve replacement followed by chemotherapy. The histopathology revealed B-cell non-Hodgkin lymphoma (NHL) with tumor cells showing immunoreactivity with CD20 and negative for CD45RO.
