Show Hint
Perimenopausal abnormal uterine bleeding with thickened endometrium = endometrial biopsy.
Updated On: May 14, 2026
- Hysterectomy
- Endometrial biopsy
- HPV testing
- Progesterone therapy
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question:
A perimenopausal patient with Abnormal Uterine Bleeding (AUB) and a significantly thickened endometrium (16 mm) must be evaluated to rule out serious pathology.
Step 2: Detailed Explanation:
Clinical Thresholds: In any woman over the age of 45 presenting with heavy or irregular bleeding, the priority is to exclude Endometrial Hyperplasia or Endometrial Carcinoma.
Endometrial Thickness (ET): While 16 mm is not diagnostic of cancer by itself in a premenopausal woman, it is thick enough to warrant histological investigation when symptoms of AUB are present.
Diagnostic Modality: Endometrial biopsy is the "gold standard" first-line diagnostic step.
It can often be performed in an office setting using a Pipelle suction curette. If the biopsy is insufficient or the bleeding persists, a Dilation and Curettage (D and C) with Hysteroscopy would be the subsequent step.
Inappropriate Steps: Hysterectomy is a treatment, not a diagnostic step; you must have a histological diagnosis before proceeding to major surgery.
Progesterone therapy may be used to treat simple hyperplasia, but it cannot be given until malignancy is ruled out.
HPV testing is for cervical screening and is irrelevant for endometrial pathology.
Step 3: Final Answer:
Tissue sampling via endometrial biopsy is the most appropriate next step to rule out endometrial malignancy in this age group.
