A giant ovarian mucinous cystadenoma in a postmenarchal adolescent girl

Background. Giant mucinous cystadenomas are rare in adolescents and young adults. Case Presentation. We report a mucinous cystadenoma in a 16-year-old postmenarchal girl presented with abdominal distention and pain, and elevated serum CA-125 levels. Radiological evaluations showed a large cystic mass originating from the right ovary. The patient underwent successful surgery with complete resection of the tumor without rupture and the histopathological examination confirmed the diagnosis of a benign mucinous cystadenoma. Conclusion. The case emphasizes the importance of early diagnosis and the need for total surgical resection without rupture to ensure a favorable outcome in such cases and close follow-up is recommended.
