ABSTRACT
Hormone-producing malignancies are rare in children or adolescent patients Only 0.1% of all ovarian tumors and 4-5% of granulosa cell tumors occur in the sexually non-active ages. Granulosa cell tumors (GCTs) are sex cord-stromal tumors of the ovary, representing 7-8% of all ovarian neoplasms. A total of 95% of all GCTs are adult-type, and only 5% are diagnosed as juvenile-type GCT. A majority of children with juvenile-type GCT present with isosexual precocious pseudopuberty due to excessive estrogen production, although virilizing, testosterone-producing, juvenile-type GCTs are rare, occurring only in 2-3% of cases. The present case study reports on a case of a virilizing, juvenile-type GCT in a 14-year-old girl, along with a review of the literature.
