Description: (Location & Drainage)

The external iliac lymph nodes are a group of 8–10 nodes situated along the external iliac artery and vein (Földi et al., 2012). This nodal group can be further subdivided into four groups: the medial, intermediate, lateral, and obturator lymph nodes.

The external iliac nodes receive lymphatic drainage from the deep layers of the abdominal wall, below the umbilicus, pelvic viscera (including the fundus of the bladder, urethra, cervix, superior part of the vagina and prostate), the perineum, and from the inguinal lymph nodes.

The external iliac lymph nodes send efferent lymph vessels to the common iliac lymph nodes, which send lymph to the lateral aortic and caval lymph nodes of the left and right side, respectively.
