Q: I have been getting boils for about 5 years. They are quite big,
usually on or under my breast and between my legs. Sometimes they burst
on their own or I have to get them lanced. I have read that recurrent
boils are a symptom of diabetes. Is this true? Right now I have 3 under my
breast and 2 between my legs. Can you tell me anything about this?
Dr. Donnica: A boil is an inflamed, pus-filled swelling of the skin. A cluster
of boils is called a carbuncle. Boils are caused by certain bacteria, especially
Staphylococcus aureus, which infect a hair follicle. In defense, your white blood cells
move in. This produces pus (white or yellow), which is simply white blood cells,
bacteria, and dead skin cells. Boils are very common, usually appearing on the face,
neck, breasts, and buttocks. They can occur and recur in people who are otherwise
healthy, however, people with lowered resistance to infection, including those with
diabetes, do have an increased sensitivity. It would be worth discussing this with
your doctor and getting screened for diabetes, especially if you have a family
history. In the meantime, you can apply hot, damp cloths to the boil both to reduce
the pain and to hasten spontaneous drainage.
It may also be worthwhile to consult a dermatologist to rule out a condition called
Hidradenitus Supperativa (HS). This condition has been called by many other names
including "acne inversa," but is not well known among patients or physicians. Its
name describes its appearance: oozing, inflamed sweat glands. This sometimes
debilitating autoimmune disorder appears as severe, recurrent boils. Unfortunately,
it can often take up to 10 years to diagnose this condition correctly because of
limited awareness by healthcare professionals and extreme embarrassment from the
nearly one million Americans who suffer from it. Of even greater concern is that its
cause is unknown, there is no known consistently effective treatment, and no major
research effort under way to aggressively seek a cure.
HS is a non-contagious, recurrent skin disease usually found in areas of the body where
there is skin-to-skin contact (such as armpits, groin, thighs, and under breasts) and
around hair follicles where apocrine sweat glands are located. Characteristically, it
progresses from boils or abscesses to hard lumps and painful, rounded deep-seated
inflamed lesions with subsequent scarring and chronic seepage (aka suppuration).
These hard lumps occur under the skin and may grow as large as baseballs. In many
cases, they are very painful and may persist for years with or without recurrent
inflammation. Inflamed lumps may lead to extensive drainage, which may cause the
development of sinus tracts under the skin. These may heal slowly or not at all, which
may lead to further inflammation and lumps. Bacterial infections are possible at these
sites. Draining the lumps may provide some pain relief, but the lumps and tracts often recur.
Because HS may be extremely painful and the drainage may have a foul odor, sufferers often
limit their activities including work or even going out in public. As a result, HS sufferers
often suffer from depression as well.
For unknown reasons, HS is often associated with several other conditions including
polycystic ovarian syndrome (PCOS), insulin resistance, diabetes, Crohns disease, anemia,
hyperhidrosis, acne, and pilonidal cysts.
