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.
