Sebaceous Cyst Removal
Why Waiting Can Make It Worse (And What to Do Instead)
Patients Often Ask
Before you read the full article, here are the things Chattanooga patients often want to know:
-
It’s a slow-growing bump under the skin filled with keratin — most are technically epidermal inclusion cysts, not true sebaceous cysts.
-
Almost always benign. Infection or rupture can cause pain and redness.
-
Many don’t go away and can grow or become inflamed over time.
-
Observation is possible, but early removal often results in a better cosmetic outcome and lower risk of infection.
If you’ve noticed a bump under your skin - maybe on your neck, back, face, or scalp - you’re not alone. These little lumps are extremely common and usually harmless. But what they are, when they should be treated, and how to get rid of them safely is something many Chattanooga residents actively search for, before booking care.
That’s exactly what we’ll walk through below.
What Is a “Sebaceous Cyst”?
Healthcare professionals typically call these epidermal inclusion cysts (EICs) - and that’s because most of the bumps people call “sebaceous cysts” don’t actually form from sebaceous glands.
An epidermal inclusion cyst:
Grows just below the surface of your skin
Often has a tiny central pore (punctum)
Is filled with keratin — a natural skin protein
Usually feels smooth and moveable
They’re most often found on the:
Back
Neck
Face
Scalp
Pilar cysts, also called trichilemmal cysts, commonly occur on the scalp and arise from hair follicles, often feeling firm, smooth, and mobile under the skin — and like other cysts, they are best removed completely to prevent recurrence.
Upper chest
And they can range from pea-sized to several centimeters across.
How and Why Cysts Form
These cysts form when normal skin cells or follicular debris get “trapped” beneath the skin instead of shedding off. Over time, the trapped cells make keratin, which fills a tiny sac and gradually enlarges.
A few things that can contribute:
Blocked hair follicles
Previous acne or folliculitis
Trauma to the skin
Chronic inflammation
Conditions like hidradenitis suppurativa (HS)
Cysts associated with HS are different from typical epidermal inclusion cysts because they are part of a chronic inflammatory skin condition and often require broader medical management in addition to surgical treatment.
Hormonal influences such as from testosterone replacement therapy (TRT)
When cysts form repeatedly, that pattern deserves evaluation - not just a one-time removal.
Should You Worry About a Cyst?
Most cysts are benign - meaning they’re not cancerous.
That said, you should schedule an evaluation sooner, rather than later, if you notice:
✔ Rapid growth
✔ Redness, warmth, or tenderness
✔ Drainage or unpleasant odor
✔ Interference with daily activities
✔ Cosmetic concern
Here’s why - once a cyst becomes infected or inflamed, treatment becomes more urgent and the procedure can be more uncomfortable - and scars may be larger.
“Leave It Alone If It’s Not Bothering You” - Valid Advice?
You’ll hear this from many providers. And in certain situations, it can be appropriate to monitor a cyst that’s stable and not causing symptoms.
Here’s the catch:
Many cysts grow slowly and eventually become noticeable.
Some enlarge quicker than expected.
Waiting can lead to painful inflammation, rupture, or infection.
Once inflamed or infected, you often need antibiotics or drainage, which can affect scarring.
At Clear Derm, we typically recommend evaluation early - especially if the cyst is visible, growing, or you’re unsure what it is.
Treatment Options - What Works Best?
1. Conservative Management (Initial)
For small cysts that aren’t inflamed:
Steroid injections can reduce swelling temporarily.
Observation may be reasonable if there’s no irritation.
However, while injections make the cyst softer and less inflamed, they do not remove the cyst wall and therefore aren’t typically permanent.
2. Definitive Removal - When It’s Time
The most effective way to prevent recurrence is a controlled surgical excision performed under local anesthesia in the office.
Here’s why technique matters:
➡ The entire cyst wall (capsule) and punctum need to be removed
➡ Leaving part of the wall behind is a common reason cysts grow back
➡ Removal before infection typically leads to a smaller scar and faster healing
This meticulous approach is the gold standard in dermatology and why specialist care improves outcomes.
