The superficial inguinal lymph nodes form a chain immediately below the inguinal ligament.

They lie along the great saphenous vein, deep to Camper's fascia and superficial to the cribriform fascia which overlies the femoral vessels.

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.

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
• vulva
• anus (below the pectinate line)
• the lower extremity (foot, leg and thigh)

Division

They are divided into three groups:

• Supramedial or Superomedial
• Superolateral
• Inferior
