The superficial inguinal lymph nodes are the inguinal lymph nodes that form a chain immediately below the inguinal ligament.
They lie deep to the fascia of Camper which overlies the femoral vessels at medial aspect of the thigh.
They are found in the femoral triangle bounded by the inguinal ligament superiorly, the border of the sartorius muscle laterally, and the adductor longus muscle medially.
There are approximately 10 superficial lymph nodes. Inguinal lymph nodes may normally be up to 2 cm in size.[1]
The superficial nodes drain to the deep inguinal lymph nodes.
Afferents received
They receive lymphatic afferents 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:
- Superomedial
- Superolateral
- Inferior
