    This study details a rare case of a testosterone-producing granulosa cell tumor in a premenopausal woman, highlighting virilization symptoms. Hormonal analysis revealed the steroidogenesis pathway, offering insights into rare ovarian tumors.

    Area of Science:

    • Reproductive endocrinology
    • Gynecologic oncology
    • Steroid biochemistry

    Background:

    • Granulosa cell tumors (GCTs) are rare ovarian neoplasms.
    • Virilization is an uncommon clinical sign associated with GCTs, occurring in approximately 2% of cases.
    • Comprehensive hormonal investigations in virilizing GCTs are infrequently reported.

    Observation:

    • A premenopausal woman presented with amenorrhea and clinical signs of virilization.
    • Histological examination confirmed a granulosa cell tumor.
    • Hormonal profiling revealed elevated testosterone levels and characteristic peripheral-ovarian hormone gradients.

    Findings:

    • The granulosa cell tumor was identified as the source of excess testosterone production.
    • Analysis of hormone gradients elucidated the specific steroidogenic pathway involved in testosterone biosynthesis within the tumor.

  • This case provides a detailed hormonal profile of a virilizing GCT.

    • Implications:

    • This case expands the understanding of the endocrine manifestations of granulosa cell tumors.
    • The findings contribute to the diagnostic and management strategies for patients with virilizing ovarian neoplasms.
    • Further research into the steroidogenesis of rare ovarian tumors is warranted.
