Urethral Caruncle Pictures: Signs, Symptoms, and Diagnosis

A urethral caruncle is a small, fleshy growth that appears at the opening of the urethra, and it is the most common benign tumor of the female urethra. It typically looks like a reddish or pinkish rounded mass, sometimes described as rose-colored, protruding from the urethral opening. While the word “tumor” sounds alarming, a caruncle is almost always harmless, though its appearance can understandably cause concern because it can resemble something more serious.

What a Urethral Caruncle Looks Like

If you are searching for pictures of urethral caruncles, you are probably trying to compare a growth you or your doctor noticed to known examples. The typical caruncle appears as a soft, round or oval swelling at the urethral meatus, the external opening of the urethra. Clinical descriptions consistently note a reddish, pinkish, or rose-colored mass with a broad base, usually arising from the back wall of the urethral opening. The growth is generally not painful when touched.

Size varies, but most caruncles are small. An ultrasound study of 20 patients found that the widest diameter ranged from about 8 to 32 millimeters, with a midpoint around 17 millimeters, roughly the size of a pea to a small grape.¹ Most appear as oval nodules, though about one in five may wrap partially around the urethra in a Y-shape rather than forming a neat round bump.

Color is one area where caruncles can be tricky. Most are some shade of red or pink because they are highly vascular, meaning they have a rich blood supply. But some can appear darker, ranging to purple or even black.² That darker coloring is exactly why some caruncles get confused with melanoma, a topic covered further below. The surface may look smooth or slightly irregular, and in some cases the tissue bleeds easily when touched or wiped.

Symptoms You May Notice

Roughly a third of urethral caruncles cause no symptoms at all and are found incidentally during a routine pelvic exam or by the person herself while bathing. A study examining 41 cases found that about 32% of patients had no symptoms whatsoever.³ When symptoms do occur, the most common ones are bleeding, blood in the urine, pain, burning or discomfort during urination, or awareness of a lump at the urethral opening.⁴

In that same 41-case study, pain was the most common complaint at about 37%, followed by blood in the urine at 27% and painful urination at 20%.³ Some people also report spotting on underwear, particularly after physical activity or intercourse. In rare cases, a large caruncle can partially obstruct the flow of urine.⁵

Who Gets Them and Why

Urethral caruncles overwhelmingly affect postmenopausal women. The exact cause is not fully understood, but the decline in estrogen levels after menopause is considered a significant factor.⁶ Lower estrogen leads to thinning and drying of the urethral and vaginal tissues, making them more prone to irritation, inflammation, and the kind of tissue overgrowth that produces a caruncle.

Under a microscope, caruncles can look quite different from one another. Some show abundant tiny blood vessels, others display overgrowth of the surface tissue, and still others feature a pattern of inflamed granulation tissue.⁷ These histological patterns explain why caruncles vary in appearance from bright red and vascular to pale and fleshy, even though they are all the same condition.

While rare, caruncles do occasionally appear in children and premenopausal women. A case series from Northern Tanzania documented three pediatric patients with the condition.⁸ In children, the trigger appears to be chronic inflammation rather than estrogen deficiency, and the growth tends to appear right at the center of the urethral opening rather than from the back wall, as is typical in adults.⁹ Pediatric caruncles can present with vaginal bleeding, which has in at least one case been mistaken for early onset of menstruation in a four-year-old girl.¹⁰

How Doctors Diagnose a Urethral Caruncle

Most caruncles are diagnosed on physical examination alone. A doctor can usually recognize the characteristic soft, red growth sitting at the posterior lip of the urethral opening. In straightforward cases where the lesion looks classic and is causing no alarm, a clinical diagnosis without further testing is standard practice.

When there is any doubt, further investigation may include cystoscopy, where a thin camera is passed through the urethra into the bladder. This lets the clinician see the relationship between the growth and the urethral wall and check for any additional lesions inside the urethra or bladder. Cystoscopy is invasive, though, and it cannot evaluate structures around the urethra.¹

Ultrasound is emerging as a helpful, noninvasive alternative. Transvaginal ultrasound can reveal a solid lesion arising from the urethral wall and help measure its size and shape.¹¹ A dedicated ultrasound study found that the technique can reliably identify the growth, measure its distance from the bladder neck, and distinguish its borders from surrounding tissue.¹ This can be especially useful when the growth is unusually large or when the clinician wants to plan a surgical approach.

The single most important diagnostic step, when warranted, is biopsy. If the growth has any features that raise suspicion for malignancy, an excisional biopsy, removing the entire growth and sending it to a pathology lab, is the definitive way to confirm the diagnosis. Even when clinical suspicion for cancer is very low, excising a symptomatic caruncle that has not responded to conservative treatment serves the double purpose of relieving symptoms and confirming what the tissue actually is.

Conditions That Can Look Similar

Several other conditions can mimic a urethral caruncle, and distinguishing among them matters because the treatment and urgency differ. A British urology consensus document lists the main benign lesions in the same area as urethral mucosal prolapse, Skene’s gland cysts, and urethral diverticulum, alongside caruncles themselves.¹²

Urethral prolapse: This involves the urethral lining everting outward in a full circle around the opening, whereas a caruncle typically arises from just one side, usually the back wall. Prolapse also tends to lack the inflammatory component seen in a caruncle.⁵
Skene’s gland cyst or abscess: These uncommon periurethral lesions can cause chronic vulvar pain and urinary symptoms that overlap with caruncle symptoms. Because these glands sit right next to the urethra, accurate identification matters to avoid accidental urethral injury during any procedure.¹³
Urethral diverticulum: A pouch that forms along the urethra wall, which can sometimes bulge outward and be mistaken for a caruncle. Imaging, typically MRI, is usually needed to tell the difference.
Urethral melanoma: Rare but serious. Most urethral melanomas in women involve the outer third of the urethra and can appear as a polypoid mass. Some are amelanotic, meaning they lack dark pigment, making them look very much like a garden-variety caruncle. Conversely, a darkly pigmented caruncle can look like a melanoma.²
Urethral carcinoma: Extremely rare in women, but a caruncle-like mass that is fixed, hard, ulcerated, or growing rapidly warrants biopsy to rule it out.¹⁴

Red Flags That Prompt a Biopsy

The vast majority of urethral caruncles are harmless, and malignant urethral tumors in women are exceptionally rare. Still, certain features should prompt your doctor to send tissue to the lab rather than simply watching or treating with cream. A mass that is firm or fixed in place rather than soft and mobile, one that has an irregular surface or nodular texture, one that is ulcerated, or one that keeps growing over time all raise concern.¹⁴ Swollen lymph nodes in the groin, extension of the mass into surrounding tissue, or failure to respond to a reasonable trial of topical estrogen cream are additional signals that biopsy is indicated.²

Early diagnosis of a malignancy like urethral melanoma is critical because these cancers can spread quickly. A misdiagnosis or delay can meaningfully worsen the outcome. So the guidance from urological literature is clear: when in doubt, biopsy. The risk of removing a benign growth for nothing is trivial compared to the risk of missing a rare cancer.

Treatment for Benign Caruncles

If a caruncle is small and not causing symptoms, the standard approach is simply to watch it. Many caruncles remain stable for years without growing or causing problems. For those that do cause discomfort, bleeding, or urinary symptoms, treatment typically starts with conservative, non-surgical measures.

Topical Treatments

First-line therapy for a symptomatic caruncle that does not look suspicious is topical medication. The options include estrogen cream applied directly to the area, anti-inflammatory ointments, or topical steroid creams. Sitz baths, where you sit in a shallow tub of warm water for ten to fifteen minutes, can also help reduce irritation and swelling.

These conservative approaches work well in many cases. One case report documented a caruncle resolving completely with topical estrogen cream alone.¹⁵ In that patient, a combination of twice-daily sitz baths and daily application of a steroid cream led to significant improvement at six weeks and complete disappearance by two years of follow-up. Because the underlying issue in postmenopausal women often involves estrogen-depleted tissue, replenishing estrogen locally makes physiological sense and addresses the root vulnerability.

Surgical Options

When a caruncle does not respond to topical treatment, causes significant symptoms, or needs to be biopsied, surgical removal is the next step. Several techniques are used. Traditional approaches include simple excision, cauterization, electrical fulguration, and a clamp-and-cautery method.¹⁶

A newer technique using a holmium laser has shown promising results. A comparative study found that laser resection took an average of about six minutes compared to roughly 28 minutes for conventional surgery, and patients needed a catheter for about two days instead of six. Hospital stays were also shorter.¹⁷ These are meaningful practical advantages for a condition that, while benign, can still require anesthesia and a recovery period.

Recurrence after surgery is uncommon but possible. One large retrospective study of 356 patients who underwent simple excision found no recurrences. Other techniques have somewhat variable recurrence rates: the clamp-and-cautery method showed about a 3% recurrence rate in one series, while a four-quadrant excision technique had a higher rate of roughly 12%.⁶ The main surgical complication to be aware of is urethral stricture, a narrowing of the urethral channel, which occurred in about 4% of cases in one review. This is why surgeons aim to remove the caruncle tissue precisely without damaging the surrounding healthy urethra.

Caruncles in Children

Pediatric urethral caruncles are rare enough that only a handful of case series exist in the medical literature.⁸ The presentation differs from adults in a few ways. In children, the growth tends to sit at the center of the urethral opening rather than preferentially at the back wall. The primary symptom is bleeding, sometimes dramatic enough to be mistaken for vaginal bleeding rather than urethral bleeding. Adult symptoms like chronic pain and urinary burning, which are tied to estrogen-depleted tissue, are less prominent in children.⁹

Treatment also differs. While estrogen cream is the mainstay for postmenopausal women, steroid ointment is used in children because the trigger is thought to be chronic inflammation rather than hormonal deficiency. However, published pediatric cases have generally not responded well to steroid cream alone, and surgical excision has been needed in most reported cases. The good news is that curability with surgery appears to be high in children, and recurrence is uncommon.⁹

Why Pictures Alone Are Not Enough

If you have been comparing a growth to pictures online, you have probably noticed that urethral caruncles, urethral prolapse, periurethral cysts, and even rare malignancies can look strikingly similar in photos. A soft-looking pinkish bump at the urethral opening could be any of these. Pictures are useful for giving you a rough frame of reference, but they cannot replace a clinical examination. The texture of the mass, whether it is fixed or mobile, whether it bleeds with light contact, and whether it involves the full circumference of the urethra or just part of it are all things a doctor assesses by touch and direct inspection, information a photograph cannot convey.

If you have noticed a growth at your urethral opening, the most productive next step is a visit to your doctor or a urologist. For the vast majority of people, particularly postmenopausal women, the diagnosis will be a benign caruncle that either needs no treatment or responds well to a simple topical cream. For the small number of cases where something else is going on, catching it early makes a real difference in outcomes.
