Primary Cardiac Lymphoma Presenting with Thrombocytopenia, Right Heart Failure, and Cardiogenic Shock.

Primary cardiac lymphoma (PCL) is a rare, potentially fatal subtype of non-Hodgkin's lymphoma. Thrombocytopenia has also infrequently been reported in association with other primary cardiac tumours and can add substantial morbidity to an already life-threatening diagnosis if present. We report a rare case of a 70-year-old man who presented with thrombocytopenia (91 × 10/L) and progressive right heart failure.
