Inguinal Lymph Nodes

Divided into a deep and a superficial group


Superficial nodes

These are arranged in form of a letter T:

  • The vertical group along the great saphenous vein.
  • The horizontal group parallel to the inguinal ligaments.

Area Of Drainage

  • Superficial tissues of the lower limb except the lateral foot, heel and back of the leg which drain into popliteal lymph nodes.

  • Gluteal region.

  • Trunk below the umbilicus.

  • The perineum including the distal third of the anal canal, vagina and urethra

  • External genitalia except the testis and the glans penis/ clitoris

  • Fundus and the body of the uterus

Note: Inflammation (enlargement) of these nodes may signifiy infection or malignancy.


Deep nodes

These are arranged along the femoral vein and drain these areas:

  • Deep structures of the lower limb
  • Glans penis or clitoris
  • They are connected by lymph vessels to the superficial nodes and also to the external iliac nodes.

Subcutaneous Nerves and Vessels

  • Anterior cutaneous nerves of the thigh (lateral, intermediate, medial)
  • Posterior cutaneous nerve of thigh
  • Femoral branch of genitofemoral nerve
  • Cutaneous branches of obturator nerve
  • Ilioinguinal nerve
  • Subcostal nerve
