CASE PRESENTATION: We present two cases of giant SFTP diagnosed and treated between September-December 2014. Both patients were female ages 89 and 78 respectively, who had been misdiagnosed on previous outpatient imaging as having elevated hemidiaphragms. One resection was performed electively (due to chronic cough), and the other urgently (after being admitted to the ICU with respiratory distress). Both surgeries were performed after transthoracic needle biopsy confirmation, via hemi-clamshell and clamshell incisions. The first resection of a 20cm SFTP included wedge resections of the right upper and middle lobes of the lung, as well as chest wall resection and reconstruction. The second resection of a 25cm SFTP included an en-bloc left lower lobectomy and diaphragmatic resection. Both cases required intra-operative transfusions of 10 and 14 units of packed red blood cells, and were associated with hospital length of stay of 85 and 136 days respectively. Both patients survived resection and are back to baseline function.
