Pelvic lymph nodes
Pelvic lymph nodes lie in chains along the main vessels and are named after them: external iliac, internal iliac and common iliac nodes, with smaller groups beside the viscera.
Key points
- Named after vessels: external, internal, common iliac.
- Lower vagina and round-ligament lymph → superficial inguinal nodes.
- Uterine fundus and ovary → para-aortic nodes.
- Lymph sacs → lymph nodes (except cisterna chyli).
- Node: cortex (B-cell nodules) / paracortex (T cells, HEVs) / medulla.
- Afferent in at the convex side, efferent out at the hilum.
