Masculinizing granulosa cell tumour

D L Wilansky, B H Scott, R C Lachance

    Canadian Medical Association Journal
    |September 18, 1976

    Summary
    This summary is machine-generated.

    A rare ovarian granulosa cell tumor in a young woman caused menstrual irregularities and masculinization. Surgical removal of the tumor resolved these symptoms, highlighting a unique endocrine-ovarian connection.

    Area of Science:

    • Gynecologic Oncology
    • Reproductive Endocrinology
    • Pediatric and Adolescent Gynecology

    Background:

    • Granulosa cell tumors (GCTs) are the most common malignant stromal tumors of the ovary, accounting for 1-2% of all ovarian tumors.
    • While typically presenting in postmenopausal women, GCTs can occur at any age, including in premenarchal girls and young women.
    • Ovarian tumors can secrete hormones, leading to various clinical manifestations, including precocious puberty, menstrual irregularities, and signs of hyperandrogenism.

    Observation:

    • A 23-year-old female presented with oligomenorrhea, breast underdevelopment, hirsutism, and elevated serum testosterone.
    • She also reported a history of abdominal pain, nausea, vomiting, dizziness, irritability, and headaches since childhood.
    • These symptoms were associated with a benign, noncystic granulosa cell tumor of the left ovary.

    Findings:

    • The patient's symptoms of oligomenorrhea and masculinization (hirsutism, elevated testosterone) were directly linked to the presence of the ovarian granulosa cell tumor.
    • Surgical resection of the tumor led to a complete resolution of her menstrual irregularities and signs of hyperandrogenism.
    • This case adds to a very small number of documented instances linking benign ovarian GCTs to significant endocrine and physical manifestations in young women.

    Implications:

    • This case underscores the importance of considering ovarian tumors in the differential diagnosis of adolescent and young adult females presenting with endocrine disturbances and signs of hyperandrogenism.
    • Benign ovarian GCTs, though rare, can have profound effects on reproductive health and hormonal balance, necessitating prompt diagnosis and treatment.
    • Further research into the specific mechanisms by which these tumors influence hormone production and symptom development is warranted.
