A prolapsed hemorrhoid looks like a soft, grape-like mass protruding from the anus. It typically appears pink or reddish, with a moist, shiny surface that differs from the surrounding skin. The size can range from a small pea to a larger grape, and there may be one lump or several clustered together. If you’re checking yourself and wondering whether what you see matches a prolapsed hemorrhoid, the details below will help you identify what’s normal, what’s not, and what different appearances can tell you.
How a Prolapsed Hemorrhoid Looks
Internal hemorrhoids originate inside the anal canal, where they’re covered by a thin, moist lining rather than regular skin. When one protrudes outside the anus, that lining becomes visible as a soft, reddish lump. Harvard Health describes the appearance as a “small, grape-like mass.” The surface is smooth and wet-looking, and you may notice a clear or slightly cloudy mucus discharge on the tissue or your underwear.
One key visual feature is the fold pattern. Prolapsed hemorrhoids create folds that run in a radial pattern, like spokes on a wheel, fanning outward from the center of the anus. This is different from a rectal prolapse, which produces circular, ring-like folds. That distinction matters because the two conditions look similar at first glance but require very different treatment.
The number of lumps can vary. Internal hemorrhoids tend to form in three specific positions around the anal canal: left side, right front, and right back. So a prolapse may involve one, two, or all three of these cushions bulging outward at once.
What Different Colors Mean
Color is one of the most useful things to pay attention to. A typical prolapsed hemorrhoid appears pink to dark red, consistent with the moist inner lining of the anal canal. This is the most common and least concerning appearance.
A purple-blue or dark blue lump signals a thrombosed hemorrhoid, meaning a blood clot has formed inside. Cleveland Clinic describes these as a “blueish-purple lump” that is firm to the touch and often very painful. Thrombosed hemorrhoids can develop in both external and prolapsed internal hemorrhoids, and the color change is unmistakable compared to the softer pink of a non-thrombosed prolapse.
If the tissue turns very dark purple, black, or grey, that can indicate the blood supply has been cut off. This is called strangulation, and it happens when the anal sphincter clamps down on the base of a prolapsed hemorrhoid tightly enough to block blood flow. This is a situation that needs prompt medical attention.
The Four Grades of Prolapse
Not all prolapsed hemorrhoids look the same because they exist on a spectrum. Doctors classify internal hemorrhoids into four grades based on how far they protrude and whether they go back in on their own.
- Grade I: The hemorrhoid bulges slightly into the anal canal during straining but doesn’t come outside the body. You won’t see anything externally, though you may notice blood on toilet paper.
- Grade II: The hemorrhoid pushes out of the anus during a bowel movement but slides back inside on its own afterward. You might briefly see a small pink lump that disappears within minutes.
- Grade III: The hemorrhoid protrudes during straining and stays out until you physically push it back in with your finger. This is the stage where most people first notice a visible lump and start searching for answers.
- Grade IV: The hemorrhoid remains outside the anus permanently and cannot be pushed back in. These tend to be larger, more swollen, and more prone to mucus discharge and irritation.
Grade III and IV are the ones you’re most likely to see and feel. Grade IV hemorrhoids in particular can be quite prominent, sometimes described as swellings made up of engorged blood vessels rather than simple skin folds.
Prolapsed Hemorrhoid vs. Other Lumps
Several things can cause a bump near the anus, and they don’t all look the same.
External hemorrhoids form under the skin around the anus rather than inside the canal. They’re covered in regular skin (not moist lining), so they tend to match your skin tone rather than appearing pink or red. They’re also richly supplied with nerves, which is why they hurt more than internal hemorrhoids. When an external hemorrhoid thromboses, it becomes a firm, dark blue-purple lump that is intensely tender.
Anal skin tags are floppy, soft pieces of excess skin that hang from the anal opening. They’re painless, skin-colored, and flat. Unlike a prolapsed hemorrhoid, a skin tag doesn’t have a swollen, engorged quality. Skin tags often develop after a previous hemorrhoid has healed, leaving behind a small flap of stretched skin. They don’t bleed or produce mucus.
Rectal prolapse involves the entire wall of the rectum telescoping outward through the anus. It produces a much larger protrusion than hemorrhoids, often several inches long, with concentric circular folds. Prolapsed hemorrhoids, by contrast, appear as separate lumps with radial folds. If you see a large, uniform tube of tissue rather than distinct grape-like bumps, that points toward rectal prolapse rather than hemorrhoids.
Symptoms That Accompany the Appearance
What you see often comes with a specific set of sensations. A prolapsed internal hemorrhoid is usually less painful than you might expect because the tissue originates above the nerve-rich zone of the anal canal. You’ll likely feel pressure, fullness, or a sensation of something being “there” rather than sharp pain. Many people describe it as an uncomfortable awareness rather than true pain.
Mucus discharge is common with prolapsed hemorrhoids and can cause itching and moisture around the anus. You might notice staining on your underwear. Bleeding, when it happens, is typically bright red and shows up on toilet paper or in the bowl after a bowel movement. The blood comes from the surface of the hemorrhoid being irritated during straining or wiping.
If a prolapsed hemorrhoid suddenly becomes very painful, firm, and changes to a blue-purple color, a clot has likely formed. The pain from a thrombosed prolapsed hemorrhoid tends to peak within the first 48 to 72 hours and then gradually improves as the clot is reabsorbed, though the lump itself may take weeks to fully shrink.
What to Look For Over Time
Prolapsed hemorrhoids can change in appearance depending on the situation. They often look larger and more prominent after a bowel movement, prolonged sitting, or heavy lifting, then shrink somewhat when you’re lying down or resting. Grade II hemorrhoids may only be visible for a few minutes after straining. Grade III hemorrhoids stay visible until manually reduced but may pop out again later in the day.
A hemorrhoid that was once reducible but no longer goes back in has progressed from grade III to grade IV. Similarly, a hemorrhoid that was pink but turns purple or develops a hard, tender spot is showing signs of thrombosis. These visual changes are worth tracking because they help determine what level of treatment makes sense.
