A laparotomy is performed for a pelvic mass in a 29-year-old woman. The surgeon documents the anatomic distribution of all visible endometriotic implants. Which single site is MOST commonly involved by endometriosis?
- A Ovary ✓
- B Anterior cul-de-sac
- C Umbilicus
- D Rectovaginal septum
Correct answer: A. Ovary
Explanation
The ovary is the most frequent site of endometriosis, involved in the great majority of cases, followed by the uterosacral ligaments, pouch of Douglas and posterior cul-de-sac. The umbilicus and rectovaginal septum are recognised but uncommon locations, and the anterior cul-de-sac is far less often affected than the posterior one.
