Abstract:
We described here a patient who presented with symptoms of heart failure who was found to have severe bilateral impairment of atrioventricular inflow. Primary cardiac lymphoma (PCL) with extensive involvement of the two atria, pericardium and myocardium is an extremely rare tumor in immunocompetent patients. We report here a case of PCL in an immunocompetent patient with involvement of both atria and the atrial septum. The tumor had a butterfly shape. We could not do surgical excision because of the massive pericardiac invasion. The diagnosis was B-cell lymphoma and this was confirmed by the pericardiac biopsy.

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
