Background Pregnancy complicated with juvenile granulosa cell tumor (JGCT) is very rare; thus, the experience on clinical diagnosis and management is limited. Cases Two patients presented with abdominal pain, two were incidentally discovered, one by ultrasonography, and one during a caesarian section. One case received an emergency caesarian section because of tumor rupture at 38th week's gestation, the rest were treated at full term and no abnormalities were detected in the newborns. Three cases received further staging surgery, two of which received postoperative adjuvant chemotherapy. No patient had recurrent disease after a follow-up period spanning from 13 to 57 months. Conclusion In the absence of emergency, surgery can be delayed without affecting the fetus. More research is needed to determine the value of chemotherapy in FIGO stage I patients.
