A furuncle is a large infection of a hair follicle, the tiny opening in the skin from which a hair grows. Furuncles are due to an invasion of bacteria that enter the follicle and cause a bacterial infection of the follicle and nearby skin.
Furuncles are most commonly due to an infection of the bacterium, Staphylococcus aureus. The body tries to attack the bacterial infection by sending a surge of white blood cells (infection fighting cells) to the infected follicle. If the infection isn't stopped quickly, living and dead white blood cells, fluid, bacteria, and dead tissue collect within the infected follicle and form a deep pocket of pus. The surrounding tissue also becomes inflamed and painful.
Furuncles are often due to poor hygiene or conditions that cause a low resistance to infection. A furuncle can also be a complication of folliculitis. Symptoms of a furuncle include swelling or a reddened lump that develops in the skin. The swelling eventually emerges to the skin's surface and comes to a head of pus. In some cases a furuncle can lead to potentially serious complications, such as septicemia. For more information on complications and symptoms, refer to symptoms of furuncle.
Making a diagnosis of a furuncle begins with taking a thorough medical history, including symptoms, and completing a physical examination. A furuncle can generally be diagnosed based on symptoms and a physical exam. A culture and sensitivity test (C and S) may also be performed. This involves growing a sample of the drainage from the furuncle in the laboratory. This test determines the type of infectious organism causing the furuncle, as well as which antibiotic would be most effective in treating it.
If the furuncle is large or has lead to complications, such as cellulitis or septicemia, certain tests are generally performed. These include a complete blood count (CBC). A CBC is a blood test that measures the numbers of different types of blood cells, including white blood cells (WBCs). Different types of WBCs increase in numbers in characteristic ways during an infectious or inflammatory process, such as cellulitis or sepsis. For people who have serious or recurring furuncles, other tests may be performed to determine underlying diseases or conditions that can increase the risk of developing furuncles, such as diabetes.
It is possible that a diagnosis of a furuncle can be missed or delayed because some symptoms, such as a skin lump and inflammation, are similar to symptoms of other diseases of conditions. For more information about misdiagnosis and diseases and conditions that can mimic a furuncle, refer to misdiagnosis of furuncle.
Treatment of a furuncle varies depending on the severity of the furuncle and other factors. Treatment may include medications and possibly an incision and drainage procedure. For more information on treatment, refer to treatment of furuncle....more »
