[Appendiceal mucocele in differential diagnosis of tumors in pelvic region].

Objective: To report two cases of appendiceal mucocele in patients with suspected gynecological pathology.

Design: Case report.

Setting: Department of Obstetrics and Gynecology, Medical Faculty of Charles University and Faculty Hospital Hradec Králové.

Subject And Method: We report two cases of appendiceal mucocele diagnosed and treated at our department.

Conclusion: Appendiceal mucocele is a rare pathology, characterized by abnormal accumulation of mucous in appendix lumen. It is four times more common in females with a mean age of about 55 years. The pathogenesis could be neoplastic or non-neoplastic. Appendiceal mucocele with its anatomic location must be considered in terms of differential diagnosis of masses in pelvic region. Preoperative diagnosis is important, alerting the surgeon of an unintended rupture during surgery and avoiding the development of pseudomyxoma peritonei. US and CT were reported to be valuable.
