    Abstract:
    BACKGROUND: Pathology of the appendix represents >50% of surgical activity. It is necessary to consider rare pathologies such as mucoceles. These have a high frequency in females with a F/M ratio of 4:1, as well as in patients >50 years of age. The objective of this study is to report on a case of mucinous cystadenoma of the appendix. CLINICAL CASE: We present the case of a 34-year-old male with a history of juvenile rheumatoid arthritis diagnosed at 9 years of age. At 22 years of age, the patient underwent bilateral hip arthroplasty. Since 1998, the patient has presented with renal amyloidosis and has been under steroid treatment to date. The current problem evolved 1 year ago during control studies for his disease. Computed tomography (CT) of the abdomen was done, demonstrating a tumor in the right iliac fossa. Colonoscopy confirmed a tumor with smooth edges located in the cecum. Surgery was recommended with a diagnosis of lipoma of the cecum. During surgery, a large tumor was found, indicating a poor prognosis. Right hemicolectomy was done. Surgical specimen was sent to pathology with a report of mucinous cystadenoma. CONCLUSIONS: The group of symptoms of cystadenoma is nonspecific. Diagnostic methods include X-rays, ultrasound, CT and colonoscopy. Mucinous cystadenoma is the most common form of mucocele of the appendix. Diagnostic protocols are the same for benign appendix pathology. Treatment is surgical and type of surgery depends on the size of the mucocele. Mucoceles of the appendix are pathologies with a favorable prognosis when appropriate treatment is done.
