Inguinal hernia or Hesselbach's triangle, an area defined by the edge of the rectus abdominis muscle, the inguinal ligament and the inferior epigastric artery. These hernias are capable of exiting via the superficial inguinal ring and are unable to extend into the scrotum. When a patient suffers a simultaneous direct and indirect hernia on the same side, the result is called a "pantaloon" hernia (because it looks like a pair of pants, with the epigastric vessels in the crotch), and the defects can be repaired separately or together. Since the abdominal walls weaken with age, direct hernias tend to occur in the
Inguinal lymph nodes nodes. They lie medial to the femoral vein under the cribriform fascia. The uppermost node is in the groin, under the inguinal ligament, and is called Cloquet's node (also Rosenmuller's node). This node is named for French surgeon Jules Germain Cloquet, or for German anatomist Johann Christian Rosenmüller. It can also be considered as the lowest of the external iliac lymph nodes. Cloquet's node is also considered as a potential sentinel lymph node. The deep inguinal lymph nodes drain superiorly to the external iliac lymph nodes, then to the pelvic lymph nodes and on to the paraaortic lymph nodes. The
