Key words: Mucocele of the vermiform appendix, surgery of minimal invasion. ABSTRACT Introduction: Mucocele of the vermiform appendix was described initially by Rokitansky in 1842, is a tumor caused by accumulate of mucinous material in the lumen, which had to obstruction of the conduit. It is uncommon, from 0.2 to 0.3% of all the apendicectomies. Histopathology classifies in hyperplasia focal or diffuse of the mucinous mucosa, cystadenoma mucinous and cystoadenocarcinoma. The clinical manifestations are not characteristic and can appear like acute appendicitis, cecal tumor, abdominal tumor, intestinal obstructive, or like finding transoperative. The rupture to the peritoneal cavity happens in a 6% and pseudomixoma is denominated peritoneal. Clinical case: Female of 54 years, with clinical manifestation of 12 months, characterized by tumor in right iliac fosse, of progressive growth, adhered to deep planes, without pain. Colonoscopy: extrinsic compression cecal. Abdominal Ultrasonography and Computed tomography report retrocecal cystic lesion. The laparoscopy with suspicion of appendiceal mucocele, and finding retrocecal cystic tumor of 12 x 8 centimeters with mucinous content. Totally laparoscopic right hemicolectomy is made, with terminal-lateral extracorporeal anastomosis, histopathology transoperative of cystadenoma mucinous. Initiates the oral route to the 72 hours of postoperative and it is withdrawn of the service to the fourth day of its entrance. Discussion: There are very few reports of the surgical management by laparoscopy, mainly before the fear of its rupture and to produce pseudomixoma, however we considered that if counts on the necessary resources as well as an adapted handling of tissues and a good experience in laparoscopy, it is feasible and safe its resolution for surgery of minimal invasion.
