Pararectal Lymph Nodes

Illustration of the lymphatic system, including the pararectal lymph nodes.

The Pararectal Lymph Nodes are a group of lymph nodes located in the pelvis, specifically in the rectum area. They are part of the body's lymphatic system, which is responsible for filtering and draining lymph fluid to prevent the spread of infection and disease.

Anatomy

The pararectal lymph nodes are situated close to the rectum, hence their name. They are typically found in clusters and are connected to other lymph nodes in the pelvic region, including the paraaortic lymph nodes and the internal iliac lymph nodes.

Function

The primary function of the pararectal lymph nodes, like all lymph nodes, is to filter lymph fluid. This fluid contains white blood cells, which help to fight off infections. The pararectal lymph nodes are particularly important in preventing the spread of diseases and infections in the lower digestive tract and the pelvic region.

Clinical Significance

The pararectal lymph nodes are often examined in the diagnosis and treatment of certain cancers, particularly colorectal cancer and prostate cancer. Enlargement or swelling of these nodes may indicate the presence of cancer cells, and their removal may be necessary as part of treatment.
