Retroperitoneal Mucocele of the Appendix: Diagnostic Problem (A Case Report)

Appendicular mucocele is a rare pathological entity, of variable clinical presentation, often identified incidentally on imaging or during surgical exploration for an unrelated diagnosis. The diagnosis of certainty is mainly anatomo-pathological. We report the case of a 49 year old female patient with no previous surgical history in whom we discovered this condition in an incidental manner. The clinical presentation was that of an acute appendicular syndrome and revealed a mass in the right iliac fossa. The patient underwent a right hemicolectomy with ileocolic anastomosis and the anatomopathological study confirmed mucinous adenocarcinoma. The postoperative course was simple.
