Sebaceous Adenoma: Causes, Symptoms, and Treatment

What kind of doctor treats Sebaceous Adenoma?
Skin growths are often first checked by a primary care doctor or a dermatologist. A gastroenterologist manages colon cancer screening when the growths suggest Muir-Torre syndrome. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
A sebaceous adenoma is a small, harmless growth that starts in a sebaceous gland, an oil-producing gland in the skin. It is benign, meaning it is not cancer and does not spread. It usually looks like a small, yellowish bump.
Symptoms
It usually appears as a single small bump that is yellow, orange, or skin-colored, firm or slightly soft, and rarely hurts. A bump that hurts, bleeds, changes quickly, or breaks open should be examined by a doctor.
Causes and who gets it
Doctors do not always know why these growths form. They are more common in older adults, and medicines that suppress the immune system may raise the risk.
In some families, they are linked to Muir-Torre syndrome, a rare inherited condition related to Lynch syndrome, which raises the risk of several cancers, especially colon cancer. Doctors take them seriously when a person has several.
How doctors diagnose it
A doctor often suspects one just by looking at the skin. To confirm it, the doctor may take a small sample, called a biopsy, to examine under a microscope.
With many tumors or a family history of colon cancer, the doctor may order genetic testing or a colonoscopy.
Treatment
Most do not need treatment because they are harmless. If a growth is bothersome, a doctor can remove it by cutting, freezing, or using a gentle electric current.
Once removed, it usually does not come back. When growths are linked to Muir-Torre syndrome, treatment focuses on regular cancer screening, especially of the colon.
When to see a doctor
See a doctor for any new skin growth, especially one that grows quickly, changes color, bleeds, or causes pain. Several oily-looking bumps can signal an inherited condition that needs cancer screening.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either kind can examine a growth, arrange a biopsy, and remove benign growths, referring to a dermatologist or gastroenterologist if needed.
Common questions
Is a sebaceous adenoma cancer?
No. A sebaceous adenoma is benign, which means it is not cancer and does not spread. However, having several of them can be a clue to an inherited condition. So a doctor should evaluate multiple growths.
Can a sebaceous adenoma go away on its own?
These growths usually do not go away without treatment. They tend to grow slowly and stay on the skin. Removal is the usual way to get rid of one.
Does removing a sebaceous adenoma hurt?
The area is usually numbed with medicine before removal. Most people feel little or no pain during the procedure. Some soreness afterward is common and typically fades within a few days.
Why would a skin bump lead to a colonoscopy?
People with Muir-Torre syndrome develop sebaceous tumors and have a higher risk of colon cancer. Because of this link, doctors may recommend colon screening when a person has several of these growths or when there is a family history of colon cancer.
