a long-standing collection of pus surrounded by fibrous tissue.
An abscess with pus but without signs of inflammation. It usually develops slowly as a result of liquefaction of tuberculous tissue. It may occur anywhere in or on the body but more frequently in the spine, hips, genitourinary tract, and lymph glands. Symptoms may be very mild. Pain, when present, is caused by pressure on surrounding parts; tenderness is often absent. Chronic septic changes accompanied by afternoon fever may occur. Amyloid disease may develop if the abscess persists for a prolonged period.Synonym: cold abscess
