What is Reactive lymphadenopathy?
Lymphadenopathy or lymphadenitis refers to lymph nodes which are abnormal in size, number or consistency and is often used as a synonym for swollen or enlarged lymph nodes. Common causes of lymphadenopathy are infection, autoimmune disease, or malignancy.
Inflammation as a cause of lymph node enlargement is known as lymphadenitis. In practice, the distinction between lymphadenopathy and lymphadenitis is rarely made. Inflammation of the lymphatic vessels is also known as lymphangitis. Infectious lymphadenitides affecting lymph nodes in the neck are often called scrofula.
The term comes from the word lymph and a combination of the Greek words , adenas ("gland") and , patheia ("act of suffering" or "disease").
Due to its peculiar high incidence, the presence of lymphadenopathy is a particularly important sign on the diagnosis of HIV or even, untreated later stages of the infection, AIDS.
