Description
The superomedial superficial inguinal lymph nodes usually contain two nodes that are located near the terminal ends of the superficial epigastric and external pudendal veins.
This group of nodes receive lymphatic drainage from the anterior abdominal wall, inferior to the umbilicus, the external genitalia, perineum, anus, lower third of the vagina, and uterine horns in females or the skin of the scrotum in males.
Their efferent vessels pass to the external iliac nodes, with some intercalated vessels passing to the deep inguinal lymph nodes.
