Successful laparoscopic treatment of a giant solitary fibrous tumor of the mesorectum: A case report and literature review.
A solitary fibrous tumor is a ubiquitous mesenchymal fibroblastic tumor that was previously considered limited to the pleural cavity. Here, we report a rare case of a large solitary fibrous tumor of the mesorectum, which was successfully resected laparoscopically. A 56-year-old woman was referred to our hospital for a giant pelvic mass. Pelvic MRI showed a well-circumscribed mass, 12 cm in diameter, with heterogeneous signal intensity on T2-weighted images. It was diagnosed as a benign mesorectal tumor of unknown origin. We successfully resected the entire tumor laparoscopically. Histological examination revealed it to be an extrapleural solitary fibrous tumor. For large tumors in the pelvis, the laparoscopic approach is preferable in terms of intraoperative hemorrhage, as long as they do not invade surrounding tissues.
