Retention mucocele of the appendix is caused by a variety of obstructive lesions such as postinflammation, fecalith, carcinoid tumor, and endometriosis. Appendiceal mucocele due to endometriosis is extremely rare; only one documented case of such condition has been recorded in the literature. We describe a young black woman who had abdominal pain, nausea, and vomiting. Abdominal exploration revealed a small retention mucocele caused by endometriotic obstruction at the distal segment of the appendix. No evidence of endometriosis in other organs was found. The patient was asymptomatic after appendectomy.

Appendiceal mucocele is a rare clinical condition that causes distension of the appendix lumen with mucus. A seventy-three-year-old female patient presented with complaints of abdominal pain, nausea, and vomiting. Abdominal examination revealed mild tenderness, right lower quadrant pain upon palpation, rebound tenderness and muscular rigidity, and a palpable mass. Abdominal ultrasonography and computed tomography scans demonstrated a cystic lesion in the right iliac fossa, adherent to the cecum, suggesting an abdominal abscess. An emergency operation was performed, during which a diagnosis of a mucocele of the appendix was made. Surgical treatment included appendicectomy, partial resection of the ileum, and resection of the cecum. Histopathologic examination confirmed the operative diagnosis. The role of imaging and clinical approach is emphasized in the treatment of an appendiceal mucocele, especially in emergency settings.

Appendiceal mucocele is a rare disease (0.3% of all appendectomy) and is characterized by the accumulation of mucoid material in the appendiceal lumen. Etiopathogenesis can be inflammatory or neoplastic. Four entities can be distinguished on the basis of histopathologic epithelial characteristics: simple appendiceal mucocele (AM), mucocele with epithelial hyperplasia, cystadenoma and cystadenocarcinoma; the last two subgroups represent neoplastic forms. Dissemination of neoplastic cells and mucoid material in abdominal cavity, caused by appendiceal perforation, clinically results in pseudomyxoma peritonei which is the dramatic evolution in 10-15% of cases. Clinically it can remain either asymptomatic for long time or it can manifest with abdominal pain that can be associated with the presence of a palpable mass. The most common clinical manifestation is pain in the right iliac fossa. Preoperative diagnosis is rare, while it is more frequently intraoperative. Therapy is fundamentally surgical: appendectomy is curative for simple AM, for AM with epithelial hyperplasia and for cystadenoma with intact appendiceal base; cecum resection is indicated for cystadenoma with larger base of implantation; right hemicolectomy has been the elective treatment in case of cystadenocarcinoma for several years although Gonzalez-Moreno and Sugarbaker have recently demonstrated its validity as definitive treatment only if it is performed in order to obtain complete cytoreduction, if there is lymph node involvement, or if histopathological examination indicates non-mucinous type. We report the case of a 60-year-old woman that presented with cystic neoformation in the right iliac fossa, that was preoperatively considered deriving from the ovary. We intraoperatively found the presence of appendiceal mucocele that histological examination defined as mucinous cystadenoma.

Appendiceal mucocele (AM) is rare disease found in <1% of all appendectomy specimens. AM is often misdiagnosed as appendicitis because the most frequent symptom is right lower quadrant abdominal pain. AM should be considered in the differential diagnosis of abdominal pain. Although there are pathological classifications, surgical resection is accepted as the treatment to prevent the development of peritoneal pseudomyxoma (PP); however, the optimal surgical technique that must be used is unclear. We present two cases suspected of being AM prior to surgery that were pathologically diagnosed as low-grade appendiceal mucinous neoplasms. Each case progressed without developing PP. The surgical procedures we chose are considered appropriate for each case.
