Extraovarian juvenile granulosa cell tumor in a prepubertal child: novel location of a rare tumor

Juvenile granulosa cell tumor (JGCT) is the most common type of sex cord stromal tumor arising from gonadal structures of children and young adults. We present a 3.5-year-old girl with JGCT located in retroperitoneum without ovarian involvement. Extragonadal occurrences of other sex cord stromal tumors have been rarely reported, but this is the first case of JGCT in an extragonadal location. We speculate the possible underlying mechanism of sex cord stromal tumor formation in extragonadal locations. Furthermore, clinical presentation, differential diagnosis and management of this tumor in childhood are discussed.

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.
