Resection of a plasma cell granuloma combining a conventional posterolateral left-sided thoracotomy with a minimally invasive valve approach.

Plasma cell granuloma (PCG) is a rare benign tumor that is difficult to differentiate from malignancy. Depending on the location of the PCG, surgical management can be challenging. We describe a patient with a PCG involving the left lower lobe extending into the left atrium, that was resected en bloc using a conventional posterolateral thoracotomy combined with a surgical approach predominantly used for minimally invasive mitral valve surgery. This case illustrates how it is possible to utilize a technique used for cardiac surgery for tumors of pulmonary origin involving the heart.
