Zorluk: OrtaGynecologic Oncology

A 65-year-old woman comes to the clinic for a routine wellness visit. During the interview, she mentions that over the past two months, she has noticed occasional blood stains on her underwear. She attributed this to 'fragile skin' since she was recently diagnosed with vulvar lichen sclerosus and uses a prescribed topical corticosteroid ointment. Her last menstrual period was 14 years ago. She has a history of type 2 diabetes mellitus and hypertension. Her medications include metformin, lisinopril, and the topical steroid. Pelvic examination reveals white, parchment-like changes on the vulvar skin and a small anal fissure, but no active bleeding. Speculum examination demonstrates a normal-appearing cervix and vaginal vault without visible lesions. Bimanual examination is unremarkable. Transvaginal ultrasound shows a homogeneous endometrial echo complex of 9 mm9 \text{ mm}. Which of the following is the most appropriate next step in management?

  1. A
    Reassurance and continued use of topical corticosteroids
  2. B
    Follow-up transvaginal ultrasound in 3 months
  3. C
    Colposcopy with endocervical curettage
  4. Endometrial biopsyCevap
  5. E
    Measurement of serum CA-125 levels

Cevap

Endometrial biopsy
Postmenopausal bleeding (PMB) is considered to be endometrial cancer until proven otherwise. Although this patient has vulvar lichen sclerosus, which can cause pruritus and friable skin leading to spotting, the presence of a 9 mm endometrial stripe on transvaginal ultrasound strongly suggests an intrauterine source of bleeding. In a postmenopausal woman with vaginal bleeding, an endometrial thickness greater than 4 mm requires immediate tissue sampling to rule out endometrial hyperplasia or carcinoma. The most appropriate, least invasive first step to obtain this tissue is an office-based endometrial biopsy.

Adım Adım Çözüm

1
Identify the primary clinical problem and presentation.
A 65-year-old postmenopausal woman presents with vaginal bleeding (blood stains on underwear) and known vulvar lichen sclerosus.
Establishing the chief complaint helps prioritize the diagnostic workup. Any bleeding in a postmenopausal woman must be considered abnormal.
2
Evaluate the objective diagnostic findings against risk factors.
The patient has type 2 diabetes mellitus (a major risk factor for endometrial cancer) and a transvaginal ultrasound revealing an endometrial thickness of 9 mm.
In postmenopausal women with vaginal bleeding, an endometrial thickness strictly greater than 4 mm is considered abnormal and highly suspicious for pathology.
3
Determine the required diagnostic intervention.
Tissue sampling via an office endometrial biopsy must be performed.
Although the patient has a plausible alternative source of bleeding (friable skin from lichen sclerosus), the thickened endometrial stripe makes endometrial cancer a 'cannot-miss' diagnosis that mandates immediate histologic evaluation.

Anahtar Kavram

Postmenopausal bleeding requires an immediate endometrial biopsy if transvaginal ultrasound reveals an endometrial thickness greater than 4 mm, regardless of other concurrent benign pathologies.
