Scrotal cysts are almost always benign, but they can’t be safely removed at home. The only reliable way to permanently remove a cyst on the scrotum is through a minor surgical procedure performed by a doctor, typically under local anesthesia. Most scrotal cysts are epidermoid cysts (sometimes called sebaceous cysts), which are small, keratin-filled nodules that sit just under the skin. They range from about half a centimeter to several centimeters across.
What a Scrotal Cyst Actually Is
The most common type of cyst found on scrotal skin is an epidermoid cyst. These are encapsulated pouches beneath the surface of the skin filled with a protein called keratin, the same material that makes up hair and nails. They often have a small dark dot at the center called a punctum. Most of the time they cause no symptoms at all. If one ruptures, though, it can become red, swollen, and tender, and may release a foul-smelling, yellowish, cheese-like material. At that point it can look a lot like a boil.
Epidermoid cysts are the most common type of skin cyst overall and tend to appear in people during their 30s and 40s. The scrotum is one of the areas where they show up most frequently, alongside the face, neck, chest, and upper back. Some people develop a single cyst, while others get multiple.
Why You Shouldn’t Try to Remove It Yourself
It’s tempting to squeeze or pop a cyst, but doing so pushes bacteria deeper into the surrounding tissue. That can trigger a secondary infection, cause more cysts to form, and lead to scarring. On the scrotum, infection is especially concerning because the warm, moist environment promotes bacterial growth. In rare but serious cases, genital skin infections can progress rapidly into dangerous conditions that require emergency treatment.
Even if you manage to squeeze out the contents, the cyst wall remains beneath the skin. Without removing that wall, the cyst will refill and come back. This is the core reason home attempts don’t work: you’re emptying a container without removing it.
How Surgical Removal Works
The standard treatment is a minor excision. A doctor makes a small incision in the scrotal skin, carefully dissects the cyst wall away from the surrounding tissue, and removes the entire capsule. When the wall comes out intact, recurrence rates are very low. The incision is then closed with dissolvable stitches.
Most scrotal cyst removals are performed under local anesthesia, meaning the area is numbed with an injection while you stay awake. The procedure itself typically takes 15 to 30 minutes depending on the size and number of cysts. General anesthesia is an option for larger or more complex cases but is rarely needed for simple skin cysts. The surgical area may be shaved beforehand.
For cysts that are actively inflamed or infected, your doctor may first prescribe antibiotics or drain the cyst to calm things down before scheduling a full excision. Removing a cyst during active infection makes it harder to get the wall out cleanly, which increases the chance it comes back.
Which Doctor to See
For a cyst sitting on the surface of the scrotal skin, either a dermatologist or a urologist can handle the removal. A general practitioner can also perform simple excisions in many cases. If the lump feels like it’s deeper inside the scrotum, attached to a testicle, or if you’re unsure what it is, a urologist is the right starting point. They can use ultrasound to determine whether the mass is a harmless skin cyst, a fluid-filled sac like a hydrocele or spermatocele, or something that needs further evaluation.
How to Tell It Apart From Other Scrotal Lumps
Not every lump on or in the scrotum is an epidermoid cyst. Knowing the differences helps you communicate clearly with your doctor and understand the urgency.
- Epidermoid cyst: Sits in the skin itself, not attached to the testicle. Firm, movable, often has a visible central dot. Painless unless ruptured or infected.
- Spermatocele: A fluid-filled sac that forms near the top of the testicle. Usually painless and not cancerous. Feels separate from the testicle itself.
- Hydrocele: A collection of fluid between the layers of tissue surrounding the testicle. Causes diffuse swelling rather than a discrete lump.
- Inguinal hernia: Part of the intestine pushes through a weak spot in the groin and can extend into the scrotum. Often changes size with coughing or straining, and may cause a dragging sensation.
- Testicular cancer: Usually presents as a painless, hard lump on the testicle itself, or as swelling or hardening of the testicle. Any firm lump directly on a testicle should be evaluated promptly.
A simple rule of thumb: if the lump is clearly in the skin and you can pinch the skin around it while the testicle moves freely underneath, it’s likely a skin cyst. If the lump feels connected to or part of the testicle, it needs imaging.
Recovery After Removal
Recovery from scrotal cyst excision is straightforward for most people. You can generally return to light daily activities within about two days. Full recovery takes roughly two weeks. During that window, you’ll want to avoid heavy lifting (nothing over about 10 pounds for the first two to four weeks), strenuous exercise like running or swimming, and sexual activity including masturbation for at least two weeks.
Keeping the area clean and dry is the most important part of aftercare. Your doctor will likely recommend wearing snug, supportive underwear to minimize movement and reduce swelling. Some mild bruising and tenderness around the incision site is normal. You can use over-the-counter pain relief as needed. If the incision becomes increasingly red, swollen, warm to the touch, or starts draining pus, contact your doctor, as these are signs of infection.
Warm sitz baths, where you soak the area in a few inches of warm (not hot) water for 10 to 15 minutes, can help with comfort starting the day after surgery. Don’t add soap or anything else to the water, and pat dry gently afterward.
When Removal Isn’t Necessary
If a scrotal cyst isn’t causing pain, isn’t growing, and isn’t bothering you cosmetically, there’s no medical requirement to have it removed. Many people live with small epidermoid cysts for years without any problems. The main reasons to pursue removal are discomfort, repeated infections, cosmetic concerns, or uncertainty about what the lump actually is. If you’ve had a cyst confirmed by a doctor and it’s stable, watchful waiting is a perfectly reasonable approach.
