Inguinal Lymph Nodes

A Lymph Node is Oval shaped organ of Lymphatic System distributed throughout the body linked by Lymphatic Vessels. Distribution to the lower limbs is carried out through Inguinal Lymph Nodes. Inguinal Lymph Node is a type of Lymph Node present in the Inguinal Region (Groin). It is further of two type i.e.

  • Superficial Inguinal Lymph Nodes

  • Deep Inguinal Lymph Nodes

Inguinal Lymph Nodes


SUPERFICIAL INGUINAL LYMPH NODES

Superficial Inguinal Lymph Nodes form a chain beneath the Inguinal Ligament (Band running from Pubic Tubercle to the Anterior Superior Iliac Spine). They lie deep to the Camper’s Fascia (layer of Anterior Abdominal Wall) overlaying the Femoral Vessels (arteries in thigh) at the medial side of thigh. They are found in the superior border of Inguinal Ligament, lateral border of Sartorius Muscle (thin muscle running down the length of thigh) and medial border of Adductor Longus (skeletal muscle located in thigh). There are at least ten Superficial Inguinal Lymph nodes which drain into Deep Inguinal Lymph Nodes. They receive afferent lymphatic vessels from the following.

 

DEEP INGUINAL LYMPH NODES

Deep Inguinal Lymph Nodes are situated at the medial side of the Femoral Vein under the Cribriform Fascia. They are 3 to 5 in numbers. The superior node of it is present under the Inguinal Ligament and known as Cloquet’s Node. They drain into the External Iliac Lymph Nodes onto the Paraaortic Lymph Nodes.

 

CLINICAL SIGNIFICANCE

Swollen Inguinal Lymph Nodes refer to an infection like Orchitis (inflammation of Testes) in lower regions. This infection also spreads from Anal Cancer and Vulvar Cancer.
