a painful nodule formed in the skin by circumscribed inflammation of the dermis and subcutaneous tissue, enclosing a central slough or “core.” Called also furuncle. Boils occur most frequently on the neck and buttocks, although they may develop wherever friction or irritation, or a scratch or break in the skin, allows the bacteria resident on the surface to penetrate the outer layer of the skin. A carbuncle is a group of interconnected boils arising in a cluster of hair follicles.
Cause. Most boils and carbuncles are caused by Staphylococcus aureus. When these bacteria gain entrance to the skin, the infection settles in the hair follicles or the sebaceous glands. To combat the infection, large numbers of leukocytes travel to the site and attack the invading bacteria. Some bacteria and white cells are killed and they and their liquefied products form pus. The body's defenses may succeed in overcoming the invaders so that the boil subsides by itself, or the pus may build up pressure against the skin surface so that it ruptures, drains, and heals.

Boils most often afflict healthy persons but occasionally their appearance is a sign that the resistance is low, usually as the result of poor nutrition or illness. Patients with recurrent boils should be suspected of being chronic staphylococcal carriers. The nose is the most common carriage site.
Treatment. In most cases a single boil is not serious and will respond to incision and drainage. Systemic antibiotics are also sometimes indicated. Although complications are rare, a boil on or above the upper lip, on the nose or scalp, or in the outer ear can be serious because in these areas infection has easy access to the brain. Other danger zones are the armpit, the groin, and the breast of a woman who is nursing. If bacteria from a boil enter the bloodstream, septicemia may result (see blood poisoning).

A. Have you ever consulted a dermatologist (a doctor that specialize in skin problems)? He or she may diagnose the problem more accurately and address it better. What you describe may be acne or other disease that are treated by such doctors.

Without therapeutic intervention, the disease typically progresses to form more fluctuant and more painful, subcutaneous nodules that resemble large furuncles. Unlike typical furuncles, these lesions may lack characteristic central rupture and drainage, instead opening laterally and draining a thick, mucopurulent, foul-smelling fluid.
Often patients seek care from general physicians and surgeons with other diagnoses being made such as furuncles, basal cell and squamous cell carcinomas.
US 6,183,747 B1: Kaijun Ren, Sugar Land, TX, has patented a process for treating skin with acne or furuncle by applying a composition containing an effective amount of acidified pressed liquid or water extract of Momordica charactia L.
As the lesions enlarge, they may resemble a cellulitis, pyogenic furuncle, or an infected sebaceous cyst.
A boil (or furuncle) is an infection of a hair follicle that has a small collection of pus (called an abscess) under the skin.
Of the 67 patients having bacterial infections, the most common was furuncle in 41 (61.2%) cases, followed by folliculitis 11 (16.4%), cellulitis 7 (10.4%), carbuncle 5 (7.5%), and ecthyma 3 (4.5%), (Figure 2).
Differential diagnosis includes local skin infections (furuncle, carbuncle, or cellulitis), superficial wound infection after hernia repair, and infection caused by intestinal leakage.
aureus) is one of themost important pathogens in both hospitals and the community and can cause numerous syndromes in humans, such as furuncle, carbuncle, abscess, pneumonia, meningitis, bacterial arthritis, myocarditis, endocarditis, osteomyelitis, and septicemia [1-3].
In humans, the skin lesion starts as a painful red papule that gradually enlarges and develops into a furuncle. Typically, the center of the lesion has an opening, through which the larva breaths and discharges its waste products.
A furuncle or boil is a painful skin nodule associated with circumscribed inflammation of the corium or dermis and subcutaneous tissue, enclosing a central slough or core.
In Switzerland and Germany, we apply 70% alcohol on gauze wicks until the furuncle bursts spontaneously.
It is also suggested that staphylococci are commonly disseminated from the nasal cavity during talking, breathing and even exercising.5 This important pathogen not only causes mild to severe skin infections like impetigo, furuncle, ecthyma, cellulitis etc., it may also cause some invasive infections including pneumonia, endocarditis, deep-seated abscesses, toxic shock syndrome etc.6
