Superficial inguinal lymph nodes
Encyclopedia
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.
