Deep inguinal lymph nodes

The deep inguinal nodes are located within the femoral sheath, medial to the femoral vein. They receive afferent lymphatic drainage from the deep lymphatics of the distal lower extremity and perineum (e.g. glans penis / clitoris), and drain proximally into external iliac lymph nodes via channels running with the femoral vein. The deep nodes also share common channels with the superficial inguinal nodes.

The number of deep inguinal nodes is variable, and a range of 1-5 has been reported.

History and etymology

The most proximal or highest node is known as the node of Cloquet, named after Jules Germain Cloquet (1790-1883), a French surgeon with an interest in hernial disorders. This node is located just inferior to the inguinal ligament, and may also be considered the most inferior external iliac chain node. Historically, the node of Cloquet was used an an indicator of pelvic metastasis in lower extremity melanoma, although there is evidence that its predictive value is limited 4.
