You’re probably here because you found a lump. Or maybe an ultrasound tech got quiet and mentioned something about a "complex mass." Naturally, you went straight to Google. You’re looking for pictures of a dermoid cyst to see if what’s going on with your body matches the medical diagrams. It’s a weird rabbit hole. Honestly, seeing these things for the first time is a bit of a shock because they don't look like "normal" cysts. They look like something out of a sci-fi movie.
Dermoid cysts are biological oddities. They are basically tiny pockets of misplaced tissue that decided to grow in the wrong neighborhood while you were still just a cluster of cells in the womb. Because they contain "germ cells"—the building blocks for everything—they can grow hair, teeth, skin, and even bits of bone or brain tissue. When you look at pictures of a dermoid cyst, you aren't just looking at a fluid-filled sac. You’re looking at a disorganized collection of human anatomy.
What do these things actually look like?
If you're looking at external pictures of a dermoid cyst, usually found on the face or neck of a child, it just looks like a smooth, firm marble under the skin. It’s often skin-colored or slightly blue. But the internal ones—the ones doctors find on ovaries or in the brain—are where things get wild. Surgeons often describe them as "sebaceous material." That’s a fancy way of saying they are filled with a thick, yellow, buttery substance that looks like cheese or lard.
Imagine a sac the size of a lemon. Inside, there might be a long strand of hair coiled up like a spring. Sometimes there’s a fully formed molar sticking out of the cyst wall. It’s bizarre. But from a clinical perspective, these features are actually helpful. Because they contain dense things like teeth or bone, they show up very clearly on imaging.
Why the visual matters for diagnosis
Radiologists love a good dermoid cyst. Well, "love" might be the wrong word, but they are easy to spot. On a CT scan or an MRI, the fat inside the cyst has a specific "signal" that is different from water or blood. If you see a bright white spot on an X-ray where an ovary should be, and it looks like a tooth, it’s almost certainly a dermoid. Medical professionals call these "mature cystic teratomas."

The word "teratoma" comes from the Greek word teras, meaning monster. That sounds scary, but it’s just a nod to how strange they look. Most of the time, they are completely benign. They aren't cancer. They’re just... there.
Where they usually hide
You’ll find pictures of a dermoid cyst in three main spots. Each one has its own set of rules and risks.
The Ovaries
This is the most common place for adults. Often, people have no idea they have one until they get a routine pelvic exam or an ultrasound for something else. They can grow quite large—sometimes over 10 centimeters. The big risk here isn't the cyst itself, but something called "ovarian torsion." Because the cyst is heavy (thanks to the hair and teeth), it can cause the ovary to twist on its blood supply. That is a medical emergency. If you have sudden, stabbing pain in your lower abdomen, stop looking at pictures and go to the ER.
The Face and Neck
These are usually caught in childhood. You’ll often see them at the end of an eyebrow or on the midline of the neck. They’re usually small and harmless, but doctors like to remove them because they can get infected or grow large enough to affect a child’s vision. Unlike the ones on the ovaries, these are usually skin-deep.

The Brain and Spine
These are rarer. They usually sit right in the middle of the body. Because space is tight in the skull or spinal column, even a small cyst can cause big problems like headaches or weakness. Surgeons have to be incredibly careful when removing these because if that buttery "cheese" inside leaks out, it can cause chemical meningitis—a massive amount of inflammation.
The "Gross" Factor and Medical Reality
Let's be real: people search for pictures of a dermoid cyst because of the "ick" factor. There is a morbid curiosity about seeing a tooth growing inside an ovary. But if you are the one living with it, it isn't a curiosity; it's a source of anxiety.
You might be worried about whether it can turn into cancer. The short answer? Rarely. According to the Journal of Medical Case Reports, less than 2% of these cysts become malignant. When they do, it's usually in older women. For the vast majority of people, the treatment is just a straightforward surgery to pop it out like a grape.
Can they grow back?
This is a common question in patient forums. If a surgeon leaves even a tiny bit of the cyst wall behind, it can technically regrow. The "blueprints" for that hair and skin are still in that tissue. However, recurrence rates are generally low, around 3% to 4%.

Dealing with the diagnosis
If you’ve seen your own imaging or looked at pictures of a dermoid cyst and realized you have one, don't panic. Medicine has gotten really good at dealing with these. Most ovarian dermoids are now removed via laparoscopy—tiny incisions and a camera. You’re usually home the same day.
The biggest hurdle for most patients is the mental image. It’s hard to un-see the idea of a "monster" growing inside you. But remember, this is just a biological glitch. It’s tissue that got lost on its way to becoming "you" and decided to set up camp in the wrong spot.
What to do next
If you have been diagnosed or suspect you have one, here is the path forward.
- Check the size. If it’s under 5 centimeters and not causing pain, some doctors suggest "watchful waiting." This means an ultrasound every 6 to 12 months to make sure it isn't growing.
- Consult a specialist. For ovarian cysts, see a gynecologic surgeon. For facial ones, a pediatric surgeon or dermatologist. For spinal ones, a neurosurgeon. Don't settle for a generalist if you're nervous.
- Ask about "cystectomy." This is the surgical removal of just the cyst, leaving the rest of the organ (like your ovary) intact. Most modern surgeons prefer this over removing the whole ovary, especially if you want to have kids later.
- Prepare for the recovery. If you go the surgical route, expect some bloating and soreness for about a week. It’s much easier than a "traditional" open surgery.
- Ignore the horror stories. You will find some wild stuff online. Remember that people only post the most extreme cases. The "boring" 2-centimeter dermoid that was removed without drama doesn't make it onto TikTok.
Dermoid cysts are one of the body’s weirdest quirks. They look terrifying in photos, but they are incredibly well-understood by doctors. If you’re looking at pictures of a dermoid cyst because you’re scared, take a breath. It’s a common, treatable condition that surgeons see every single week. Get the imaging done, talk to a pro, and get it handled. You'll feel a lot better once that "tooth" is in a pathology lab and not in your abdomen.
Key Takeaways for Patients
- Dermoid cysts are not caused by anything you did; they are congenital (present from birth).
- They are almost always benign (non-cancerous).
- Imaging (Ultrasound, CT, MRI) is the gold standard for diagnosis because the fat and calcium inside show up clearly.
- Surgery is the only way to actually get rid of them; they don't dissolve with medication or diet.
- If you experience sudden, intense pain, seek immediate medical help to rule out torsion.
