We herein report an unreported case of pyogenic granuloma that originated in the pulmonary artery. A 38-year-old man was urgently hospitalized with dyspnea and back pain. He had been on hemodialysis for 2 years due to chronic renal failure. We performed contrast-enhanced computed tomography and detected a mass occluding the left main pulmonary artery. The maximum standardized uptake value (SUVmax) of 18F-fluorodeoxy glucose (FDG) in the mass was 4.1. We made a tentative diagnosis of pulmonary artery tumor, and planned an operation. We performed median sternotomy and left anterolateral thoracotomy. As the tumor had not reached the bottom of the left pulmonary artery, we first performed left upper lobectomy. We then performed resection of the pulmonary artery tumor under cardiopulmonary bypass and reconstructed the pulmonary artery with self-pericardium. The pathological diagnosis was pyogenic granuloma. To our knowledge, pyogenic granuloma originating in the pulmonary artery has never been reported before.
