A Rare Case of Juvenile Granulosa Cell Tumor in a Premenarchal Female: Clinical Presentation, Diagnosis, and Management

Juvenile granulosa cell tumors (JGCTs), a rare type of ovarian tumor, are predominantly seen in premenarchal girls. We report a case of a 4.5-year-old girl with precocious puberty and a left ovarian JGCT, confirmed through imaging and histopathology. The patient underwent a fertility-sparing unilateral salpingo-oophorectomy, and no recurrence was observed after one year of follow-up. Surgery is the mainstay of treatment for early-stage JGCTs, and the role of adjuvant chemotherapy in advanced cases remains unclear. This report underscores the importance of early diagnosis and long-term monitoring in pediatric patients with ovarian masses.
