Inguinal Lymph Nodes - Learn about Enlarged Groin Symptoms
Inguinal lymph nodes are located in the crease between the leg and the pelvis. It is the lymphatic drainage that drains the penis, scrotum, vulva, vagina, perineum, gluteal region, lower abdominal wall, and the lower anal canal. These nodes can be enlarged due to infections of the leg or foot, STDs (e.g., herpes, syphilis, granuloma inguinale, lymphogranuloma venereum), lymphoma, pelvic malignancy, bubonic plague etc.
The inguinal lymph can be further classified to superficial inguinal lymph nodes and deep inguinal lymph nodes. The superficial inguinal lymph nodes are located right beneath the inguinal ligament. These lymph nodes seem to form a chain of nodes. Approximately, there are about 10 inguinal lymph nodes present at the medial aspect of the thigh. The superficial inguinal lymph nodes can be further divided into 3 categories i.e. supramedial or superomedial, superolateral and Inferior. The superficial inguinal lymph nodes drain into the deep inguinal lymph nodes.
The inguinal lymph nodes are located under the ciribriform fascia. This is the portion of fascia that covers fossa ovalis in the thigh. There are about 3-6 deep nodes. Cloquet’s node is the most superior nodes that are located right under the inguinal ligament. The sign of swollen inguinal lymph nodes is an important sign as indicates infection in the lower portion of the body. It could also be a sign of spread from anal or vulvar cancer.
