title: Laparoscopic resection of retroperitoneal benign schwannoma.
abstract: Schwannomas are particularly rare neoplasms among tumors of the retroperitoneal space. Only 0.3-3.2% of benign schwannomas are found in retroperitoneal locations. As these tumors are usually asymptomatic and discovered by chance or in the course of the evaluation of an unrelated health problem, they may cause the delay of early diagnosis and treatment. With recent advances in the field of minimally invasive surgery, several laparoscopic approaches to retroperitoneal schwannomas have been reported. In this paper, we present the case of a 59-year-old female patient with an asymptomatic retroperitoneal mass that was found during a regular medical checkup. The mass was located between the inferior vena cava (IVC) and aorta under the pancreaticoduodenal unit (site of lymph node 16b1), compressing the IVC. She underwent successful laparoscopic surgery for retroperitoneal schwannoma. In addition, we summarized the literature on cases regarding the laparoscopic management of the retroperitoneal schwannoma.
