The lymphatic system encompasses a network of vessels, glands, and organs located throughout the body. Functioning as part of the immune system, it also acts to transport fluids, fats, proteins, and other substances within the body. Lymph nodes, or glands, filter the lymph fluid. Lymphangitis is defined as an inflammation of the lymphatic channels.
Inflammation occurs as a result of infection at a site distal to the channel.
Pathogenic organisms invade the lymphatic vessels and then spread along these channels toward regional lymph nodes. Pathogenic organisms enter the lymphatic channels either directly, through an abrasion or wound, or as a complication of an infection. Once the organisms enter the channels, local inflammation and subsequent infection ensue, manifesting as red streaks on the skin. The inflammation or infection then extends proximally toward regional lymph nodes. No specific data are available.
