An Inguinal lymph node is a type of lymph node in the inguinal region. It can refer to:

A view of the different inguinal lymph nodes
  • Superficial inguinal lymph nodes
    • inferior -inferior of the saphenous opening of the leg, receive drainage from lower legs
    • superolateral - on the side of the saphenous opening, receive drainage from the side buttocks and the lower abdominal wall.
    • superomedial - located at the middle of the saphenous opening, take drainage from the perineum and outer genitalia.[1]
  • Deep inguinal lymph nodes
    • arranged near and along the femoral vein of the leg.
    • drain the deep parts of the lower limbs, women's clitorus, and men's penis
    • connected to the superficial lymph nodes and send their drainage to those via lymph vessels.[2]

The mean size of an inguinal lymph nodes, as measured over the short-axis, is approximately 5.4 mm (range 2.1-13.6 mm), with two standard deviations above the mean being 8.8 mm.[3]
