Overview
Lymphangitis is inflammation of the lymphatic system, a system that is comprised of small vessels of the immune system that carry lymphatic fluid. The fluid is filtered in the lymph nodes and spleen, drained into the subclavian veins through thoracic duct and finally returned back to the circulatory system. Depending on the etiologies, lymhangitis has a spectrum of pathophysiology.
Pathophysiology
- Lymphatic vessels are thin walled, valved structures situated in deep dermis and sub-dermis tissues.[1]
- Lymph follows the following pattern of drainage: [1]
- Lymph from tissues drain into the regional lymph nodes via afferent lymphatics, then to right lymphatic duct and thoracic duct via efferent lymphatics, and finally into venous circulation via one of the subclavian veins.
Settings involved in pathogenesis of disease are: [2][3]
- Normal Lymphatic vessels:- Invasion of microorganisms either from traumatized skin, or from a distal site of infection into the lymphatic vessels that leads to inflammation of the vessel.
- Anatomical abnormalities resulting in obstruction of lymphatic channels or damage to the lymphatic vessels, as seen in setting of surgery, malignancy, and trauma.[4]
Depending on etiologies, lymphangitis has spectrum of pathophysiology:
Lymphangitis due to infectious etiology
Acute lymphangitis
Acute lymphangitis, develops in setting of distal trauma, resulting in infection. Infection, if not contained locally, may spread through lymphatic channels resulting in lymphangitis.[2][3]
Chronic Granulomatous Lymphangitis
Chronic granulomatous lymphangitis, develops in the setting of minor trauma to extremities (e.g., wood splinter or rose bush). Distal infection spreads through an indolent process, resulting in subcutaneous nodules along the course of lymphatic channels.[2][3]
Filarial lymphangitis
Filarial lymphangitis develops when thread like adult filarial worms resides in lymphatic channels and lymph nodes, resulting in inflammatory changes to the lymphatics.[5]
Lymphangitis due to Non-infectious etiology
Lymphangitis carcinomatosa
Lymphangits carcinomatosa is a dreadful condition, that develops due to extensive lymphatic permeation and embolization of lymphatic capillary by tumor cells.[6][7]
Sclerosing lymphangitis
- The exact pathophysiology of sclerosing lymphangitis remains unclear. However, many patients report increase in sexual activity before the appearance of lesion, indicating idiopathic nature of the disease.[8]
Light microscopic and electron microscopy examination reveal:[8]
