Superficial inguinal lymph nodes

The superficial inguinal lymph nodes (often shortened to superficial inguinal nodes) form a subgroup of the inguinal lymph nodes and are located in the superficial fascia of the upper thigh near the inguinal ligament and great saphenous vein.

They number around ten, although a range of 5-17 nodes was reported in a cadaveric study, and drain lymph from the gluteal region, inferior anterior abdominal wall, perineum and superficial lower limbs . They drain into the external iliac lymph nodes via lymphatic channels accompanying the femoral vessels.
