Introduction: Primary retroperitoneal mucinous cystic neoplasm is very rare and its histogenesis is unclear.
Presentation of case: This paper presents the case of a 31-year-old female in whom an incidentally detected retroperitoneal cystic mass, 6.5cm in size, was successfully resected through laparoscopic approach. Pathologic examination revealed a mucinous cystadenoma. The postoperative course was uneventful, and the patient remained free of recurrence six months after surgery.
Discussion: Literature review showed that male sex (p=0.019), and solid nodules in cysts (p<0.001) were both significantly associated with malignancy.
Conclusion: When confronted with a cystic mass in the retroperitoneum, a primary mucinous cystic neoplasm should be considered and complete surgical removal of the tumor without spillage is recommended.
