Left-sided primary cardiac lymphoma diagnosed by needle biopsy with total endoscopic anterolateral mini-thoracotomy: a case report.

Herein, we report an extremely rare case of PCL located on the left side of the heart. Owing to the location of the tumour, percutaneous or transcatheter biopsy could not be performed. Early diagnosis with needle biopsy via anterolateral mini-thoracotomy and systemic chemotherapy resulted in good outcomes.
