MINETTI, Ángel M et al. Laparoscopic approach of a retroperitoneal schwannoma. Rev. argent. cir. [online]. 2019, vol.111, n.1, pp.36-39. ISSN 2250-639X.

Benign neurogenic retroperitoneal tumors are rare, usually asymptomatic or present non-specific symptoms as a palpable mass or compression of the surrounding structures. Functional tumors are associated with hypertension. Due to their rarity, location and relationship with the surrounding vascular structures, the use of the laparoscopic approach to remove these tumors is unusual, and the routine use of this strategy has not been clarified yet. We report the case of a 40-year-old female patient with an ultrasound showing a retroperitoneal mass adjacent to the inferior vena cava. A transperitoneal approach was decided and the technique is described. Operative time was 46 minutes, blood loss was 10 mL, pain was minimal and hospital stay was 48 hours. The pathological examination and immunohistochemical tests revealed the presence of a schwannoma. Follow-up image tests and clinical examination at 14 months were normal. The considerations of this rare condition are made, concluding that transperitoneal laparoscopic approach for retroperitoneal masses is feasible with all the advantages provided by this method.
