Clinical Evaluation and Comprehensive Care Tailored to You
Understanding Skin Cysts
Finding a small bump on your skin that wasn’t there before is a nearly universal experience. Skin cysts are very common and, in most cases, harmless. They are closed sacs that form under or within the skin and are filled with fluid, keratin, oil, or other material produced by skin cells.
Cysts are typically painless, so they’re easy to overlook. Many people only realize they have these growths of where they are located or how they feel during daily activities. For example, you might notice a firm bump on your scalp while brushing your hair, or a small lump on your ankle that catches on your sock.
Cysts are considered benign neoplasms, meaning non-cancerous growths. However, they can look and feel similar to other skin conditions, which is why it’s crucial to have any new growths evaluated by a medical professional. An evaluation is the first step toward correctly treating cysts.
Symptoms of Skin Cysts
Although different types of cysts have their own characteristics, many share similar traits. A typical skin cyst may be:
- Slow-growing over weeks, months, or even years
- Painless unless it becomes inflamed, ruptured, or infected
- Skin-colored, yellowish, or slightly white in appearance
- Firm or rubbery to the touch, often with a smooth surface
- Slightly movable under the skin rather than fixed in place
Most true skin cysts have a thin lining, or sac, under the skin that produces or traps material such as keratin or fluid. This lining is what allows the cyst to refill if it is drained but not entirely removed.
Some cysts also develop a small central opening, known as a punctum, which may be visible on the surface of the skin.
Because cysts can vary widely in how they look and behave, understanding the type of cyst involved helps guide what comes next, including whether monitoring or treatment is the best approach for the patient.
Types of Skin Cysts
There are several types of skin cysts, which doctors categorize based on where they originate and what they contain. Here are some examples:
Epidermoid Cysts
Epidermoid cysts are the most common type of skin cyst. They form when cells from the epidermis, the uppermost layer, become trapped in the dermis, the deeper layer. There, they continue producing keratin, which accumulates and forms a thick, soft material within a balloon-like pocket.
Epidermoid cysts often appear as slow-growing, round bumps beneath the skin. They’re commonly found on the face, neck, trunk, or back and may have a visible central pore.
Its subtypes include:
- Epidermal inclusion cysts, which can develop after minor skin trauma
- Infundibular cysts, which arise from the upper part of a hair follicle
Epidermoid cysts are usually painless unless they become inflamed or infected.
Pilar (Trichilemmal) Cysts
These cysts are relatively rare, affecting about 10% of the population. They develop from hair follicles and are most often found on the scalp, although they can appear on any part of the body that grows hair, like the legs, arms, and face.
Pilar cysts tend to feel firmer than epidermoid cysts and usually do not have a visible pore. While they’re typically painless, they can become tender if irritated by brushing or pressure. They can also grow very large, to the size of a marble or even a golf ball, over a period of many years. As a result, they can cause distress or self-consciousness.
Subtypes include proliferating trichilemmal cysts, a less common variant that may grow more quickly.
Milia
Milia are tiny cysts that form when keratin becomes trapped just beneath the skin’s surface. They appear as small, white or yellowish bumps and are most common around the eyes, cheeks, and nose.
Types of milia include:
- Primary Milia: Develop spontaneously in infants or adults
- Secondary (Traumatic) Milia: Form after skin injury or procedures
- Milia en Plaque: A rare pattern involving clusters of milia on inflamed skin
Milia are harmless and are often mistaken for acne or whiteheads.
Sebaceous-Related Cystic Conditions
True sebaceous cysts are rare, but several cystic conditions involve oil glands and are often labeled this way.
These include:
- Steatocystoma Simplex: A single oil-filled cyst
- Steatocystoma Multiplex: A condition involving multiple small cysts, often on the chest or arms
These cysts contain an oily fluid rather than keratin and may appear during adolescence or early adulthood.
Hair Follicle–Related Cysts
Some cysts are linked to fine body hair rather than larger hair follicles. One example is eruptive vellus hair cysts, which appear as small, dark bumps and contain tiny hairs.
These cysts are often mistaken for acne or clogged pores and tend to appear on the chest or upper arms.
Developmental and Congenital Cysts
Certain cysts are present at birth or develop from tissue remnants left behind during development.
Examples include:
- Dermoid Cysts: May contain skin structures such as hair or glands
- Thyroglossal Duct Cysts: Typically found in the neck
- Branchial Cleft Cysts: Often appear in the neck or near the jaw
These cysts often require careful evaluation, imaging, and monitoring.
Infection-Related or Inflammatory Cysts
Some cyst-like lumps form because of infection or ongoing inflammation rather than a buildup of skin cells. These areas may become red, swollen, tender, or drain fluid, and they often feel more painful than other types of cysts.
Some examples are:
- Pilonidal cysts: Fluid-filled abscesses that form near the tailbone
- Acne cysts: Seen in severe or nodulocystic acne
Pseudocysts
Not every lump called a “cyst” is a true cyst. Pseudocysts don’t have a defined lining and behave differently.
Examples include:
- Digital Mucous Cysts: Shiny, fluid-filled growths that form near the ends of fingers or toes
- Ingrown Hair-related Bumps: Result from inflammation around trapped hair
- Cystic Acne Lesions: Pockets of inflammation rather than sacs
Treatment for pseudocysts differs from that of true cysts. Because there is no sac or lining to pull out, it typically involves draining the fluid and then using methods to make the empty space collapse and heal.
Evaluation and Diagnosis of Skin Cysts
At Connolly Dermatology, we leverage years of experience as practicing, board-certified dermatologists as well as advanced clinical tools to evaluate and diagnose cysts. Your input as the patient is also highly important. Information from your personal experience, like how long the cyst has been present, whether it has changed, or if it has caused discomfort, help us with our evaluation, how we classify the growth, and determine what steps come next.
Physical Examination
In many cases, we can identify a skin cyst through a visual examination and palpation, our touch. During your visit, we look for specific features that help distinguish cysts from other types of lumps.
We assess:
- Surface details, such as a visible central pore or smooth skin covering
- Mobility, by gently moving the lump to see if it shifts under the skin
- Texture, which may feel firm, rubbery, or fluid-filled
Ruling Out Other Conditions
An essential part of diagnosis involves distinguishing cysts from other common skin lumps. As mentioned, many skin conditions share similarities with cysts but require different management.
Conditions that patients sometimes mistake for cysts include:
- Fatty growths like lipomas
- Abscesses caused by infection
- Dermatofibromas, which present as small, hard bumps
- Certain skin cancers, like basal cell carcinoma, that may appear cyst-like
Categorizing the Cyst
After evaluation, we determine how the cyst is behaving or progressing and what that means for care.
Cysts are often categorized as:
- Quiescent or Quiet: Stable or does not grow, painless, and exhibits no symptoms
- Inflamed: With redness or swelling but no infection
- Infected: With pain, drainage, or warmth
This classification helps guide whether monitoring, medication, or procedural treatment is appropriate. For instance, a quiet or quiescent cyst might be monitored only or removed simply for cosmetic reasons. Meanwhile, an infected cyst that has formed an abscess requires immediate medical care.
Advanced Diagnostic Tools
When a cyst is larger, deeper, or located in a sensitive area, we may use additional tools to understand its structure better.
Depending on the situation, this may include imaging tools such as the following:
- Dermoscopy: Your dermatologist will use a dermatoscope, a high-magnification handheld lens, to examine your skin’s surface patterns and structures not visible to the naked eye.
- High-frequency Ultrasound: Imaging allows your dermatologist to see the depth and boundaries of the cyst. It also tells them if there are nearby blood vessels or nerves, which must be avoided if the cyst needs to be surgically removed. .
- MRI or CT Scan: This is rarely used for simple skin cysts, but your dermatologist might order it for Baker’s cysts or Branchial cleft cysts.
Laboratory Confirmation
When a cyst is surgically removed, we send the specimen to a specialized pathology lab for a definitive diagnosis. Most cysts are benign, but this extra step allows for clinical verification and provides patients with peace of mind.
Lab evaluation may include:
- Pathology: A pathologist looks at the tissue sample under a microscope to confirm the type of cyst removed. They also check for abnormal or cancerous cells.
- Culture: If the cyst appears infected, the doctor may take a swab of the fluid to pinpoint the specific bacteria and prescribe the appropriate antibiotics.
Skin Cyst Treatment Options
Treatment depends on the type of cyst, whether it’s causing symptoms, and how it’s behaving over time.
Observation and Monitoring
Not all cysts need to be treated right away. If a cyst is small, painless, and not causing any problems, your dermatologist may recommend simply keeping an eye on it. Monitoring involves watching for growth, redness, tenderness, drainage, or repeated inflammation. This approach eliminates the need for unnecessary procedures.
Cortisone Injections
For cysts that become inflamed, swollen, or painful but are not infected, a cortisone injection may help calm the inflammation. Treating cysts in this way can reduce redness, tenderness, and size over several days. While it doesn’t remove the cyst itself, it can make symptoms more manageable and may help avoid rupture or infection.
Incision and Drainage
If a cyst becomes infected or very painful, your dermatologist may recommend draining it. This involves making a small opening to release trapped material and reduce pressure. Drainage can provide quick relief, but the cyst wall often remains, which means the cyst may return later.
Surgical Removal
Complete surgical excision removes both the cyst and its lining. This is the most reliable way to prevent recurrence. Surgical removal is often recommended for cysts that keep coming back, become infected repeatedly, grow larger, or cause cosmetic concerns.
Treatment of Underlying Conditions
Some cysts are linked to ongoing skin conditions, such as acne or genetic cyst disorders. In these cases, treatment may also focus on managing the underlying issue to reduce the formation of new cysts. This might include topical or oral medications, depending on the situation.
When Treatment Is Recommended
You should consider treating cysts if they:
- Become painful, red, or swollen
- Drain or show signs of infection
- Grow quickly or changes in appearance
- Keep coming back after healing
- Cause discomfort or cosmetic concern
A dermatologist can help you choose the treatment path appropriate for the type of cyst you have, while also taking into account any concerns regarding its appearance.
What to Expect During Recovery From Surgical Cyst Removal
Recovery after cyst removal is usually straightforward, especially when the entire cyst and its lining have been removed. What you experience depends on the size of the cyst, its location, and how your skin heals.
Most procedures are done in the office using local anesthesia, which means you can go home the same day. It’s normal to notice mild soreness, swelling, or redness at the site for a short period after the treatment.
Immediately After the Procedure
After removal, we’ll cover the area and review aftercare instructions with you. You may be asked to:
- Keep the site clean and dry for a set period
- Apply an ointment as directed
- Avoid friction or pressure on the area
If your procedure required stitches, we’ll let you know when they should be removed and what to expect during that time.
Healing Over the Next Few Weeks
You may notice scabbing or slight tenderness. This is normal and part of the healing process. Most people can return to daily activities quickly, though we may suggest limiting strenuous activity depending on the location of the cyst.
Scarring varies from person to person and depends on factors like where the cyst was located and how deep it was. We’ll discuss ways to support healing and minimize visible marks with you before and after treatment.
Follow-Up and Results
If the cyst was sent to the lab, we’ll review the pathology results with you once they’re available. This confirms the diagnosis and helps determine whether any additional care is needed.
Follow-up visits allow us to check healing, remove stitches if needed, and answer questions that come up after the procedure. If you’ve had cysts before, we may also talk about what to watch for in the future.

Frequently Asked Questions
Will a skin cyst go away on its own?
While a cyst can occasionally shrink on its own, it usually doesn’t disappear completely unless the cyst lining is removed. If a cyst changes, becomes painful, or keeps coming back, treatment may be worth discussing.
What’s the difference between a cyst and a lipoma?
A cyst is a closed sac filled with fluid or keratin and often has a defined lining. A lipoma is a soft growth made of fatty tissue. Lipomas tend to feel softer and sit deeper under the skin, while cysts are usually firmer and closer to the surface. A dermatology exam can help you tell the difference.
Can I drain a cyst at home?
No. Trying to squeeze or drain a cyst at home increases the risk of infection, inflammation, and scarring. It can also cause the cyst to rupture under the skin, which may make it more painful and harder to treat later. If a cyst becomes swollen or tender, it’s best to have it evaluated professionally.
How do I know if my cyst is infected?
Signs of infection include:
- Increasing pain
- Redness and warmth
- Swelling
- Drainage of thick or foul-smelling material
You may also notice the area becoming more tender or rapidly enlarging. If you experience any of these symptoms, you should schedule an appointment promptly, as infected cysts often need medical treatment.
Is surgical cyst removal painful?
Cyst removal is typically done using local anesthesia, which numbs the area. Most people feel pressure but not pain during the procedure. Some soreness afterward is normal, but it usually improves within a few days. We provide aftercare instructions to help keep you comfortable as the area heals.
Will a cyst come back after treatment?
A cyst is less likely to return if both the contents and the lining are completely removed. Drainage alone may relieve symptoms, but it doesn’t remove the lining, which is why some cysts refill. We’ll talk with you about the approach that best fits your situation and your goals.
How can I help prevent AKs from returning?
Daily sun protection, regular skin exams, and monitoring for new or changing lesions support long-term management. Persistent or changing spots should be evaluated to support early detection and appropriate care.
