Notes


The external iliac lymph nodes are a group of lymph nodes located along the external iliac vessels. These nodes are part of the lymphatic system and play a crucial role in the immune response by filtering lymphatic fluid and trapping pathogens, cancer cells, and other foreign particles.

Anatomy[edit | edit source]

The external iliac lymph nodes are situated in the pelvic region, specifically along the external iliac artery and vein. They are divided into three main groups:

  • Medial external iliac lymph nodes
  • Intermediate external iliac lymph nodes
  • Lateral external iliac lymph nodes

Function[edit | edit source]

The primary function of the external iliac lymph nodes is to filter lymphatic fluid from the lower abdomen, pelvis, and lower limbs. They receive lymph from the inguinal lymph nodes and drain into the common iliac lymph nodes. This filtration process is essential for maintaining the body's immune defense mechanisms.

Clinical significance[edit | edit source]

The external iliac lymph nodes are often examined in cases of suspected cancer metastasis, particularly in cancers of the pelvis, lower abdomen, and lower limbs. Enlargement of these nodes can indicate the presence of infection, inflammation, or malignancy.
