title: [A case of retroperitoneal schwannoma of the vagus nerve].
abstract: Schwannomas are benign nerve sheath tumors that originate from any anatomical site. Most schwannomas occur in the head, neck or limbs, but rarely occur in the retroperitoneal space. Furthermore, the schwannoma originating from the vagus nerve of retroperitoneal space is much rare. We experienced a case of retroperitoneal schwannoma of the vagus nerve. A 34-year-old male was referred to our hospital for the evaluation of abdominal mass on ultrasonography. Endoscopic examination revealed submucosal tumor-like lesion on high body of the stomach. Computed tomography (CT) revealed that the stomach was compressed by a solid tumor in the retroperitoneum. On exploratory laparotomy, this mass turned out to be a baseball sized mass in the retroperitoneal space. The mass was excised in an encapsulated state. Histological examination with immunohistochemical stains revealed a schwannoma of the vagus nerve.
