Benign Sebaceous Hyperplasia

Patient Information Sheet

It's amazing how many different kinds of little growths can occur on the skin naturally. Benign sebaceous hyperplasia usually occurs as multiple little yellowish white bumps on the face. They may look like a cross between a pimple and a mole. Some have small dilated blood vessels in them. Basal cell cancer can look like this too.

So what is a benign sebaceous hyperplasia? On the face there are many tiny hair follicles. If you look closely in a mirror with the light coming from the side, you can see them as a fuzz, peach fuzz. For some unknown reason, these tiny hairs have disproportionately large oil glands associated with them. Sometimes, the oil glands will grow in a circle around the hair follicle. This over growth of oil glands produces the little bump. That's what benign sebaceous hyperplasia is.

It is not cancerous, and it is very unlikely to turn into cancer. But, sometimes benign sebaceous hyperplasias mimic basal cell cancer. I have excised about 7 benign sabaceous hyperplasias of the face because they looked liked cancer. Now, this happens several times a year to patients I refer to surgeons.

Fortunately, I have found that it is very simple to treat them using electrodesiccation. I take a very small needle electrode about the size of a hair and stick it into the bump. I stick the needle in only very superficially, about as deep as the thickness of a few pieces of paper. Then I apply electric current for about 1-2 seconds. This is called electrodesiccation. The bump turns a little white. This makes a scab in about 3-5 days. The scab comes off in about a week or two. This usually does not even leave a scar. Often they heal in just a few days.

The reason for treating benign sebaceous hyperplasias is not cosmetic. It is so they won't be confused with cancer at some future date, and then you are having surgery. Cutting does tend to cause a scar. I treat a few a week. I call it "buzzing" them.

It's not that you must have to have them treated. You can wait a year or more to be treated. I think it is wise to buzz them while they are small and easy to recognize. It is an elective procedure. Your insurance is likely to deny payment.
