A 64-year-old woman, gravida 0, presents to the clinic reporting a two-week history of intermittent vaginal spotting. She reached menopause at age 52. Past medical history includes type 2 diabetes mellitus, chronic hypertension, and obesity. Her body mass index is 38 kg/m². Pelvic examination reveals a small amount of dark blood in the vaginal vault. The cervix appears grossly normal, and the uterus is non-tender and mobile. A transvaginal ultrasound shows an endometrial thickness of 9 mm. An office endometrial biopsy is performed; however, the pathology report returns as 'scant cellular material, composed primarily of blood and mucus, insufficient for diagnosis.' Which of the following is the most appropriate next step in management?
- Hysteroscopy with dilation and curettageAnswer
- BRepeat transvaginal ultrasound in 3 months
- CInitiation of continuous oral progestin therapy
- DEndometrial ablation
- ETotal extrafascial hysterectomy
Answer
Hysteroscopy with dilation and curettage is the most appropriate next step in management.
The correct response recommends hysteroscopy with dilation and curettage. Any postmenopausal bleeding requires prompt evaluation for endometrial cancer. The initial step is often a transvaginal ultrasound; an endometrial thickness >4 mm mandates tissue sampling. While an office endometrial biopsy is the preferred initial sampling method due to its low cost and risk, it has a failure rate. When the pathology returns as 'insufficient tissue' in a patient with a thickened endometrium, malignancy has not been ruled out. The clinician must proceed to a more definitive sampling procedure, which is hysteroscopy with directed biopsy and dilation and curettage (D&C).

Key Concept
Postmenopausal bleeding with an endometrial stripe >4 mm requires definitive histologic evaluation. If an office endometrial biopsy yields insufficient tissue, a hysteroscopy with dilation and curettage is mandated to definitively rule out endometrial carcinoma.
