A case of uncontrollable hemorrhage caused by laparoscopic biopsy for large solitary fibrous tumor in the pelvis

Solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor that occurs anywhere in the body. It is often difficult to make a definite diagnosis of abdominopelvic tumors by imaging alone. Pathological information obtained by biopsy is useful. Here, the authors report a case with a large SFT of the mesometrium, in which a laparoscopic biopsy caused uncontrolled hemorrhage. A 70-year-old woman with a large solitary fibrous tumor (SFT) of the mesometrium underwent a laparoscopic biopsy that caused uncontrollable hem-orrhage. Pelvic magnetic resonance imaging revealed hyper-vascular tumor with 102-mm diameter adjacent to the uterus. Because la-paroscopic biopsy for pathological diagnosis caused uncontrollable hemorrhage, the authors performed laparotomy, hysterectomy, bilateral salpingo–oophorectomy, and ureterovesiconeostomy due to bladder injury. The tumor was completely resected. SFT was di-agnosed by histological immunostaining. Furthermore, there was no regional recurrence within 24 months of the surgery. As SFT is hyper-vascular tumor, laparoscopic biopsy should be performed with careful preparation of countermeasures for hemorrhage.
