Teratoma is a germ cell tumor with multidirectional differentiation potential, but retroperitoneal and sacrococcygeal teratomas are relatively rare.
A 32-year-old adult woman with a right duplicated ureter and left unicornuate uterus was found to have had a large pelvic mass for more than 8 years, which was increasing in size year by year.
After 2 surgeries that failed to remove the pelvic mass completely, and the biopsy of the mass only suggested that it was a mature teratoma.
The third time, after the transabdominal and transsacral combined pathway surgery, the mass was finally removed completely and found to have grown from the pelvic floor to the presacral area and finally to the right pelvic wall.
At 1-year follow-up, the patient had no complications, and serial pelvic ultrasounds showed no recurrence or metastasis.
Thus, we demonstrate the feasibility of a combined transabdominal and transsacral approach for resecting this large mature retroperitoneal teratoma of the pelvic floor, providing a reference for surgeons managing similarly complex cases.
畸胎瘤是一种具有多向分化潜能的生殖细胞肿瘤，但腹膜后和骶尾部畸胎瘤相对少见。
一名32岁成年女性，右侧重复输尿管、左侧单角子宫，发现盆腔有一较大肿物已8年有余，且肿物逐年增大。
经过两次手术均未能完全切除盆腔肿物，肿物活检仅提示为成熟畸胎瘤。
第三次手术，经腹经骶联合入路，最终完整切除肿物，发现肿物从盆底生长至骶前区域，最终延伸至右侧盆腔壁。
随访1年，患者无并发症，盆腔系列超声检查未显示复发或转移。
因此，我们证明了经腹经骶联合入路切除盆底巨大成熟腹膜后畸胎瘤的可行性，为外科医生处理类似复杂病例提供了参考。
