A 68-year-old woman comes to the office due to a 2-week history of vaginal spotting. She reached menopause 18 years ago and had not experienced any bleeding until now. Over the past month, she has also noticed new-onset breast fullness and tenderness. Her medical history is significant for type 2 diabetes mellitus and hypertension. Pelvic examination reveals a small amount of dark blood in the vaginal vault and a palpable, non-tender, 8-cm right adnexal mass. Transvaginal ultrasound demonstrates a solid and cystic right ovarian mass, and the endometrial echo complex measures 14 mm in thickness. Which of the following is the most appropriate next step in the management of this patient?
- Endometrial tissue samplingAnswer
- BQuantitative serum CA-125 assay
- CImage-guided biopsy of the adnexal mass
- DExploratory laparotomy
- EAdministration of progestin therapy
Answer
Endometrial tissue sampling
The patient's presentation of postmenopausal bleeding, a markedly thickened endometrium (greater than 4 mm), breast tenderness, and a solid/cystic adnexal mass is highly suspicious for an estrogen-secreting granulosa cell tumor. Chronic unopposed estrogen secretion by these tumors can lead to concurrent endometrial hyperplasia or carcinoma in up to 50% of cases. Therefore, any patient with a suspected estrogen-producing tumor and a thickened endometrium must undergo endometrial tissue sampling prior to definitive surgical management. Identifying concurrent endometrial malignancy is critical because it dictates the need for comprehensive surgical staging during the planned abdominal surgery.

Key Concept
Patients presenting with suspected estrogen-secreting ovarian tumors (e.g., granulosa cell tumors) and a thickened endometrium must undergo endometrial sampling to rule out concurrent endometrial malignancy prior to surgical intervention.
