Summary
This case report details an extraovarian granulosa cell tumor, a rare ovarian cancer variant. Such tumors can develop outside the ovary, even after oophorectomy, highlighting their unique origins and clinical implications.
Area of Science:
- Gynecologic Oncology
- Pathology
- Reproductive Endocrinology
Background:
- Granulosa cell tumors (GCTs) are typically ovarian neoplasms.
- Understanding the origin of GCTs is crucial for diagnosis and treatment.
- Extraovarian GCTs are exceptionally rare, posing diagnostic challenges.
Observation:
- A 67-year-old woman presented with postmenopausal bleeding and a large pelvic mass.
- The mass, measuring 16 cm, originated from the pelvic sidewall, involving adjacent organs.
- Ovaries were normal and separate from the tumor, indicating an extraovarian origin.
Findings:
- Histopathological examination confirmed the mass as a granulosa cell tumor.
- A literature review revealed a scarcity of recently reported extraovarian GCT cases.
- This case underscores the potential for GCTs to arise outside the ovary.
Implications:
- Extraovarian GCTs may originate from the genital ridge mesenchyme.
- The potential for GCT development post-oophorectomy necessitates continued surveillance.
- This case expands the known spectrum of GCT presentation and origin.
