Introduction:

The appendicular mucocele is a cystic dilation of the appendix with accumulation of mucinous material. The most frequent form of presentation is pain in the right iliac fossa; however, half of the cases are asymptomatic patients. In the present work we present a case of a patient with an incidentally diagnosis of appendicular mucocele who underwent laparoscopic appendectomy as definitive treatment.

Clinical case:

A 44-year-old male patient with no known pathological history, who underwent an abdominal ultrasound that reported a cystic tumor in the right iliac fossa. Laparoscopic surgical resolution was decided, the histological examination revealed appendicular mucocele without evidence of malignancy and satisfactory recovery of the patient.

Conclusion:

Mucinous neoplasia of the appendix is an uncommon pathology, patients are often asymptomatic or have nonspecific symptoms, and the diagnosis is made incidentally in the course of other examination. Treatment is primarily surgical and the laparoscopic approach is the choice in patients without evidence of rupture and dissemination of the disease.
