title: Laparoscopic resection of a retroperitoneal pelvic schwannoma.
abstract: Schwannomas are rarely located in the pelvis. A 54-year-old woman was found incidentally to have a tumor in the abdomen. Abdominal computed tomography and magnetic resonance imaging revealed a well-defined, heterogeneous tumor, 5 cm in diameter, in the pelvic cavity. With a diagnosis of a mesenteric tumor, a laparoscopic procedure was performed. Intra-operatively, an elastic tumor was identified in the pelvis adjacent to the right internal iliac vein and ureter. The tumor was dissected free from adjacent structures using Liga-Sure and blunt maneuvers. A complete laparoscopic excision was performed. Histopathological examination revealed a benign schwannoma. The patient had an uneventful post-operative course, and was discharged on the fourth post-operative day. Laparoscopic treatment is useful and feasible for retroperitoneal pelvic schwannoma, with minimal invasiveness and an early post-operative recovery. Thus, this procedure may be the first-choice surgical procedure for retroperitoneal pelvic schwannomas.
