Lymphangitis

Lymphangitis is an inflammation of the lymphatic channels that occurs as a result of infection at a site distal to the channel. The most common cause of lymphangitis in humans is Streptococcus pyogenes (Group A Streptococcus), but it can also be caused by other bacteria.

Causes

The most common cause of lymphangitis is an infection that has spread from a skin wound. Other causes can include bacteria such as Staphylococcus, Streptococcus, or Pasteurella. In rare cases, lymphangitis can be caused by fungi or parasites.

Symptoms

Symptoms of lymphangitis can include red streaks extending from the infected area toward the chest, fever, chills, and lymphadenopathy or swollen lymph nodes. Other symptoms can include malaise, anorexia, and myalgia.

Diagnosis

Diagnosis of lymphangitis is usually based on the characteristic clinical presentation of red streaks extending from a wound, and tenderness of the surrounding skin and lymph nodes. In some cases, blood tests may be used to identify the bacteria causing the infection.

Treatment

Treatment for lymphangitis typically involves antibiotics to fight the bacterial infection. In some cases, pain relief medication may also be prescribed. If the infection is severe, hospitalization may be required.
