[Giant appendiceal mucocele. Apropos of a case]

One case of giant appendiceal cyst secondary to obstruction is presented. The clinical feature is a pseudotumoral syndrome with the discovery of a cyst of the right iliac fossa by a pre-menopause woman. It is pre-operatively misdiagnosed as an ovarian cyst. Only an appendectomy is made for this benign lesion. The mucoceles of the appendix are rare, considered as an entity of macroscopic anatomy. The review of the literature allow us to recall the histologic classification of these lesions, their diagnostic patterns and their treatment.
