Due to its insidious onset and nonspecific imaging features, preoperative diagnosis is difficult. We reported a 34-year-old male patient with a giant pelvic SFT found incidentally during physical examination, complicated with left hydronephrosis and hydroureter. Preoperative imaging revealed a large heterogeneous enhanced mass in the pelvic cavity. Robot-assisted laparoscopic resection of the tumor was performed successfully, accompanied by simultaneous ureteral reimplantation due to severe adhesion between the tumor and the left ureter. The operation was completed with R0 resection. Postoperative pathology and immunohistochemistry (STAT6+, CD34+, Bcl-2+) confirmed the diagnosis of SFT. The patient recovered smoothly and was followed up for 12 months without tumor recurrence or complications. For selected patients with giant pelvic SFT, robot-assisted laparoscopic surgery appears to be a viable treatment option. This technique facilitates meticulous dissection and yields promising short-term clinical outcomes. However, long-term follow-up is required due to the potential for late recurrence of SFT.<\/jats:p>","DOI":"10.3389\/fonc.2026.1887824","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T08:25:01Z","timestamp":1782894301000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Robot-assisted
