"The deep inguinal lymph nodes (often shortened to the deep inguinal nodes) form a subgroup of the inguinal lymph node group, and are located within the femoral canal (medial compartment of 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 the external iliac lymph nodes via channels running with the femoral vein (the vein and lymphatics pass through the femoral septum, which is the soft tissue which seals off the femoral ring). The deep nodes also share common channels with the superficial inguinal lymph nodes."
