Obstetrics & Gynaecology · Endometrial Carcinoma

A 55-year-old woman with endometrial carcinoma has deep myometrial invasion. The primary lymphatic drainage of the uterine fundus is to which group of lymph nodes?

  • A Superficial inguinal nodes
  • B Para-aortic nodes
  • C External iliac nodes
  • D Sacral nodes
Correct answer: B. Para-aortic nodes

Explanation

The lymphatic drainage of the uterine fundus primarily follows the ovarian vessels to the para-aortic lymph nodes. The lower uterine segment and cervix drain to the pelvic nodes (obturator, internal/external iliac). Superficial inguinal nodes are involved only if the tumor invades the round ligament extensively.
