A gonadotropin-responsive virilizing granulosa tumor.
Diagnostic Gynecology and Obstetrics
|January 1, 1980
Summary
A solid granulosa-theca cell tumor causing virilization and high testosterone was effectively treated with oral contraceptives. In vitro studies confirmed the tumor
Area of Science:
- Endocrinology
- Gynecologic Oncology
- Reproductive Biology
Background:
- Granulosa-theca cell tumors (GTCTs) are the most common sex cord-stromal tumors of the ovary.
- These tumors can produce hormones, leading to various clinical manifestations.
- Virilization, caused by excess androgens, is a less common but significant presentation of GTCTs.
Observation:
- A case of progressive virilizing GTCT with significantly elevated testosterone levels is described.
- The patient's high testosterone levels were suppressed to normal following a course of oral contraceptives.
- In vitro studies revealed specific follicle-stimulating hormone (FSH) receptors on the tumor cells.
Findings:
- In vitro studies demonstrated that the tumor cells responded to gonadotropic hormones.
- The biological response, measured by cyclic AMP generation, indicated tumor sensitivity to gonadotropins.
- These in vitro findings correlated with the observed in vivo clinical response to oral contraceptives.
Implications:
- This case highlights the potential role of gonadotropins in the etiology or maintenance of ovarian tumors.
- The findings suggest that hormonal therapy, such as oral contraceptives, may be a viable treatment option for specific GTCTs.
- Further research into the interaction between gonadotropins and ovarian tumors is warranted to elucidate underlying mechanisms and optimize therapeutic strategies.
