Classic presentations involve the pleural, pericardial or peritoneal cavities. Infrequently, extracavitary solid tumours develop. Treatment of PEL requires chemotherapy and highly active antiretroviral therapy (HAART).<\/jats:p>\n               <jats:p>We report a case of a 46-year-old man, who presented with right-sided chest pain, dyspnoea and night sweats. Evaluation revealed decreased breath sounds and dullness to percussion on the right side of the chest. Imaging demonstrated a 6.1\u2005cm\u00d76.3\u2005cm right paracardial mass and right-sided pleural effusion. Pleural fluid was HHV-8 positive. The patient was diagnosed with PEL with extracavitary involvement and treated with chemotherapy and concurrent HAART.<\/jats:p>\n               <jats:p>This case is the first reported case of
