Robot-assisted laparoscopic resection of a pelvic solitary fibrous tumor

Abstract

Solitary fibrous tumor (SFT) is a rare soft tissue neoplasm of mesenchymal origin. SFT is most commonly located in the thoracic cavity (in approximately 80% of cases), but can also develop rarely in the pelvis. A 47-year-old man presented to our hospital with a pelvic tumor that was discovered during a health checkup. We performed transperitoneal robotic resection of the pelvic tumor. Intraoperative blood loss and the console time were 100 mL and 2 hours 42 minutes, respectively, and no intraoperative or postoperative complications were recorded. Histologic analysis revealed a pelvic SFT with negative surgical margins. The patient was followed-up for 13 months with no evidence of tumor recurrence. To our knowledge, this is the first report of robot-assisted laparoscopic resection of a pelvic SFT.
