Anal skin tags are small, soft flaps of excess skin that hang from the rim of the anus, often described as looking like tiny tabs or pouches of loose tissue. They range from barely noticeable nubs a few millimeters across to fleshy projections up to a centimeter or more, and their shape can be flat and broad or narrow and finger-like. Clinicians have historically grouped them into two distinct appearances, and understanding what each type looks like can help you tell a harmless tag from something that deserves medical attention.
Two Classic Appearances
Doctors who specialize in anorectal conditions have long recognized that anal skin tags tend to fall into one of two visual categories. The first type is a raised flap of skin that can be broad or narrow, single or clustered, and is typically soft, flesh-colored, and painless. These are sometimes called “elephant ears” because of the way the tissue drapes outward from the anal margin, resembling a small, rounded ear of slack skin. They may sit flat against surrounding tissue when you’re not looking closely, and you might only notice them by touch in the shower or while wiping.
The second type looks quite different. These tags tend to be swollen, firm or hard, and sometimes take on a bluish or purplish tint. They may or may not be tender, and they usually form as the aftermath of a healed anal fissure, ulcer, or hemorrhoid. Because the tissue has been through a cycle of inflammation and scarring, it often feels denser and less pliable than the first type.
Both types were described in a clinical review of anal skin tags associated with inflammatory bowel disease, where researchers noted that the “elephant ear” variety is characteristically soft and painless while the post-inflammatory type is edematous, sometimes cyanotic, and arises from prior anorectal injury.1PubMed.

Typical Size Range
Most anal skin tags are small enough that you could cover one with a pencil eraser. The majority measure somewhere between two and ten millimeters, which puts them roughly in the range of a lentil to a small pea. At the smaller end, they may feel like a tiny bump or ridge rather than a distinct flap, and people sometimes mistake them for a normal fold of skin. At the larger end, they can project outward enough to be visible when you look in a mirror or noticeable when clothing rubs against them.
Occasionally a tag grows larger than a centimeter, especially if it developed from a resolved hemorrhoid that left behind a significant amount of stretched skin. These bigger tags can look more like a soft, dangling pouch or a wrinkled fold of tissue. Size alone doesn’t indicate anything dangerous; a large tag is not more likely to be cancerous than a small one. What matters more is whether the growth changes rapidly, bleeds on its own, or has an irregular surface, all of which are reasons to have it examined.
Color and Texture
The color of an anal skin tag usually matches the surrounding perianal skin, so it may appear anywhere from pinkish to brownish depending on your overall skin tone. A tag that recently formed after a thrombosed hemorrhoid might initially look darker or have a purplish hue because of residual blood pooled in the tissue. That color typically fades over weeks to months as the blood is reabsorbed and the tissue settles into its final form.
Texture varies with the tag’s origin. Tags that developed gradually tend to be soft, smooth, and supple, much like the skin on the inside of your wrist. Tags that formed through scarring, such as those left behind by a chronic fissure, may feel firmer and slightly rougher, with a surface that doesn’t stretch as easily. Neither texture is abnormal. A tag that feels unusually hard, gritty, or wart-like, however, could be something else entirely and is worth showing to a doctor.
How to Tell a Skin Tag from a Hemorrhoid
This is one of the most common points of confusion, because hemorrhoids and skin tags often exist in the same neighborhood and sometimes one turns into the other. An external hemorrhoid is a swollen vein under the skin near the anus, and when it’s actively engorged it looks like a firm, rounded lump that may be purple or blue and is often painful. A skin tag, by contrast, is loose tissue without a swollen vein at its core, so it tends to be flatter, more pliable, and painless to touch.
Here’s where the lines blur: when an external hemorrhoid heals, the stretched-out skin may not retract fully. The leftover flap is technically a skin tag, even though the patient thinks of it as “the hemorrhoid that never went away.” If you can pinch the tissue and it feels like a thin fold of skin rather than a firm mass, it’s almost certainly a residual tag rather than an active hemorrhoid. If it’s swollen, tender, or has that taut, grape-like firmness, the hemorrhoid may still be active or there may be a new flare.
Skin Tags Versus Warts and Other Look-Alikes
Several other conditions can mimic the appearance of an anal skin tag, and some of them require treatment.
- Anal warts: Caused by human papillomavirus, these tend to have a rough, cauliflower-like surface and often appear in clusters. A skin tag, by comparison, has smooth skin and usually appears singly or in a small number. Warts also tend to grow and multiply over time in a way that skin tags do not.
- Hemorrhoidal prolapse: Tissue protruding from inside the anal canal can look like a large, moist, reddish lump. Unlike a tag, prolapsed tissue is mucosa rather than dry outer skin, so it may appear shinier and feel wetter.
- Anal polyps: Hypertrophied anal papillae or fibrous polyps sometimes project from the anal canal and can be mistaken for tags. These tend to originate higher up inside the canal and may bleed or cause a sensation of incomplete evacuation.
- Skin cancer: Rarely, a growth near the anus is a squamous cell or basal cell carcinoma. These typically have an irregular shape, ulcerate, bleed spontaneously, or grow steadily over weeks. Any new perianal growth that changes in size, shape, or color deserves a professional evaluation.
The practical takeaway is that a smooth, soft, stable flap of skin-colored tissue is likely a tag. Anything rough, rapidly growing, bleeding, or ulcerated is not, and you should have it checked.
When Skin Tags Signal an Underlying Condition
In most people, anal skin tags are a cosmetic nuisance and nothing more. But in certain clinical contexts their appearance carries diagnostic weight. Researchers have noted that in young people who also have diarrhea, abdominal pain, or growth problems, the discovery of perianal skin tags on physical exam can be an early clue pointing toward Crohn’s disease.1PubMed. Anal skin tags in inflammatory bowel disease: new observations and a clinical review In that setting, the tags tend to be the edematous, firm, sometimes cyanotic type rather than the soft “elephant ear” variety.
Perianal Crohn’s disease involves a range of nonfistulizing problems including fissures, ulcers, skin tags, and strictures, and the symptoms can be disabling. Pain, drainage, bleeding, and difficulty with hygiene are common and can significantly affect quality of life.2PubMed Central. Nonfistulizing Perianal Crohn’s Disease If your skin tags are accompanied by any of these symptoms, especially chronic diarrhea or unexplained weight loss, mention them to your doctor rather than assuming they’re benign.
Outside of inflammatory bowel disease, the presence of multiple large skin tags around the anus sometimes accompanies chronic constipation with straining, repeated bouts of hemorrhoids, or pregnancy-related changes. None of these situations make the tags themselves dangerous, but they may point to a pattern worth addressing so that new tags don’t keep forming.
Who Gets Them and How Common They Are
Skin tags in general are remarkably common. A study of 750 unselected individuals found that about 46 percent carried at least one skin tag somewhere on their body, and the likelihood increased with age, though the rate of new tags seemed to plateau around age 50.3PubMed. Skin tags: localization and frequencies according to sex and age That study covered skin tags across all body sites, but anal and perianal tags are among the most common locations because the area is subject to friction, moisture, and the mechanical stress of bowel movements.
Pregnancy is a particularly well-known trigger. Hormonal changes, increased blood volume, and the pressure of a growing uterus on pelvic veins combine to make hemorrhoids more likely during the third trimester. Once those hemorrhoids resolve postpartum, they often leave behind residual skin tags. Many women discover perianal tags for the first time after delivering a baby and understandably worry about them, but in the vast majority of cases they’re simply leftover tissue from temporary vascular swelling.
Obesity and being overweight also increase the odds. More body weight generally means more friction in skin folds and more mechanical pressure during sitting and straining, both of which contribute to the kind of tissue stretching that produces tags. People with insulin resistance or type 2 diabetes seem to develop skin tags at higher rates as well, though the connection between metabolic factors and anal tags specifically is less studied than it is for tags on the neck or underarms.
Do They Need to Be Removed
Medically speaking, anal skin tags are benign and removal is never strictly necessary. That said, they can create practical problems. A tag that sits in a fold where cleaning is difficult may trap moisture and fecal residue, leading to itching, irritation, or a feeling of incomplete cleanliness after wiping. Large tags can rub against underwear and become sore. And some people simply feel self-conscious about them during intimate situations.
Removal is typically done in an outpatient setting. The most common approaches are surgical excision with a scalpel or scissors under local anesthesia, and less frequently, cauterization or cryotherapy. Recovery is usually straightforward but can be uncomfortable for a week or two given the sensitivity of the area. Your doctor will generally want to rule out hemorrhoids, warts, or other conditions before agreeing to remove what appears to be a tag, since treatment differs for each.
One thing to keep in mind: if the underlying cause hasn’t been addressed, new tags can form in the same area. Someone who strains frequently due to chronic constipation may develop another tag within months of having one removed. Addressing bowel habits, staying hydrated, and eating enough fiber can reduce the odds of recurrence.
Changes That Warrant a Doctor Visit
Most anal skin tags sit there quietly for years without doing anything noteworthy. But a few scenarios should prompt you to seek a professional opinion sooner rather than later:
- Rapid growth: A tag that doubles in size over a few weeks is unusual. True skin tags grow slowly or not at all once they form.
- Bleeding: Tags can occasionally bleed if they get caught on clothing or are irritated by wiping, but spontaneous bleeding without trauma is a red flag for something other than a simple tag.
- Color change: A tag that turns very dark, develops white patches, or becomes ulcerated on its surface needs evaluation.
- Pain: Soft, flesh-toned tags shouldn’t hurt. A suddenly painful lump may be a thrombosed hemorrhoid, an abscess, or an inflamed fissure.
- Accompanying symptoms: As mentioned earlier, if you also have persistent diarrhea, mucus discharge, unexplained weight loss, or abdominal cramping, the tags may be part of a larger inflammatory picture.
A doctor can usually diagnose a skin tag with a visual exam alone. If there’s any uncertainty, a small biopsy under local anesthesia settles the question quickly. The tissue is sent to a pathologist, and results typically come back within a week confirming benign fibroepithelial tissue, which is the formal name for the tissue that makes up a skin tag.
Hygiene and Day-to-Day Management
If you have anal skin tags and aren’t planning to have them removed, a few simple habits can keep them from becoming a nuisance. After a bowel movement, consider using a gentle, unscented wet wipe or a quick rinse with water rather than dry toilet paper alone. Dry paper can irritate the tag and doesn’t clean the folds as well. A handheld bidet attachment, which has become inexpensive and widely available, solves both problems at once.
Keep the area dry after cleaning. Moisture trapped under a tag can lead to fungal overgrowth or contact dermatitis, both of which produce itching that’s easy to confuse with the tag itself being the problem. Patting dry with a soft towel or letting the area air-dry briefly before getting dressed helps. Avoid using talcum powder or cornstarch in the perianal area, as these can cake in folds and make things worse.
Wearing breathable, cotton-based underwear reduces friction. If a particular tag catches on fabric during exercise, a small amount of petroleum jelly applied to the tag before a workout can act as a lubricant and prevent irritation. These are unglamorous steps, but they make a real difference for people who find their tags bothersome on a daily basis.
