A case of primary cardiac lymphoma in a twelve-year-old patient with right-heart failure

Primary non-Hodgkin’s lymphoma usually presents as a rapidly growing mass inside the heart chambers or myocardium. Most prevalent symptoms are arrhythmia, treatment-resistant heart failure, pericardial effusion and embolic strokes. However, secondary lymphomas are mainly infiltrated inside the heart tissue. This article is a case report of a non-Hodgkin’s lymphoma in a 12 years old boy; whose clinical manifestations were palpitation, exertional dyspnea, weight loss and constitutional symptoms. Due to worsening of symptoms beside medical treatments, and mass obstructing right ventricle filling, urgent cardiac surgery was preformed. Mid-sternotomy was done and epicardial pacemaker was implanted. After pericardiotomy and during biopsy, hypotension and cardiac arrest was happened that was not reversed after long CPR. Post mortem biopsy was compatible with lymphoblastic lymphoma.
