The superficial inguinal lymph nodes form a chain immediately below the inguinal ligament.
They lie deep to Camper's fascia which overlies the femoral vessels at medial aspect of the thigh.
They are found in the triangle bounded by the inguinal ligament superiorly, the border of the sartorius muscle laterally, and the adductor longus muscle medially. (Femoral Triangle of Scarpa)
There are approximately 10 superficial lymph nodes.
The superficial nodes drain to the deep inguinal lymph nodes.
Afferents received
They receive as afferents lymphatic vessels from the following:
- integument of the penis
- scrotum
- perineum
- buttock
- abdominal wall below the level of the umbilicus
- back below the level of the iliac crest
- vulva
- anus (below the pectinate line)
- the thigh and the medial side of the leg (the lateral leg drains to the popliteal lymph nodes first).
Division
They are divided into three groups:
- Supramedial or Superomedial
- Superolateral
- Inferior
