Internal iliac lymph node

Internal Iliac Lymph Nodes

The Internal iliac lymph nodes, also known as hypogastric lymph nodes, are a group of lymph nodes located in the pelvis. They play a crucial role in the lymphatic system, which is part of the body's immune system.

Anatomy

The internal iliac lymph nodes are situated along the internal iliac artery and its branches. They are divided into several groups, including the anterior and posterior groups, based on their location relative to the internal iliac artery.

Function

The primary function of the internal iliac lymph nodes is to filter lymph, a fluid that contains white blood cells that help fight infections. They also play a role in the body's immune response by producing and storing cells that fight infection and disease.

Clinical Significance

The internal iliac lymph nodes are often involved in the spread of various types of cancer, including cervical cancer, prostate cancer, and rectal cancer. Enlargement of these lymph nodes, known as lymphadenopathy, can be a sign of infection, immune disease, or cancer.
