Tick or Skin Tag? How to Tell the Difference

Is It a Tick or a Skin Tag?

Look for a separate oval or rounded body, tiny legs and a narrow attachment point. These features suggest a tick.

A skin tag is usually continuous with the surrounding skin. It may be soft, flexible, flesh-colored or pigmented and does not have legs.

At a glance:

• Tick: Separate body with legs, attached at the front.
• Skin tag: Skin tissue growing outward, without legs.
• Tick: May become larger and rounder after feeding.
• Skin tag: Usually changes slowly rather than suddenly.
• Tick: May appear after outdoor exposure.
• Skin tag: May have been present for weeks, months or longer.

Do not pull, twist, cut or squeeze the bump while you are unsure. Mistaking a skin tag for a tick can injure the skin, while delaying removal of a confirmed attached tick is also undesirable.

Tick or Skin Tag: Quick Comparison

No single feature is conclusive. Use several features together and inspect the point where the bump meets the skin.

Signs That the Bump May Be a Tick

A tick is a separate organism attached to the surface of the skin. Its appearance varies according to its species, life stage and whether it has fed.

It has visible legs

Nymphal and adult ticks have eight legs. The legs are usually grouped around the front or sides of the body.

On a small or engorged tick, the legs may be hidden beneath the body, hair, fur or a skin fold. Examine the area from several angles.

It has a distinct body

A tick usually has an oval, rounded or seed-like body that appears separate from the surrounding skin.

An unfed tick is generally flatter. A feeding tick may become larger, smoother and more rounded.

It is attached at the front

The tick’s mouthparts are located at the front of its body. The main body sits above the skin and is anchored at a relatively small attachment point.

The legs may move

Sometimes the legs move when the surrounding hair or fur is disturbed. Do not poke, squeeze or rotate the tick to test whether it moves.

It appeared after outdoor exposure

A new bump found after walking, hiking, gardening or spending time in grass, woodland or brush deserves careful inspection.

Pets may pick up ticks after outdoor walks, roaming, hunting or resting near vegetation.

It becomes larger over a short period

A feeding tick can expand as it takes a blood meal. The abdomen may become rounded, grey, tan, brown or blue-grey.

A sudden change does not prove that a bump is a tick, but it is an important reason to inspect it promptly.

It feels firm or seed-like

An attached tick may feel like a small seed, bead or firm bump. Touch alone is not enough for identification because normal skin features can feel similar.

It has a darker front and lighter body

An engorged tick may have a pale, swollen abdomen with darker legs and mouthparts near the front.

Signs That the Bump May Be a Skin Tag

A skin tag is a growth of skin tissue. Its appearance varies between people and animals, and not every soft or stalk-like bump is necessarily a harmless skin tag.

It has no legs

A skin tag does not have legs, mouthparts or a separate outer body.

Look carefully around the entire base. Hair, shadows and folds can sometimes create lines that resemble legs.

It is continuous with the skin

The bump may emerge directly from the skin or hang from a narrow stalk. Its surface usually resembles skin rather than the outer shell of a parasite.

It feels soft or flexible

Many skin tags feel soft and may move slightly with the surrounding skin.

Do not pinch, twist or pull the bump to test its flexibility. This can cause pain, bleeding or irritation.

It matches the surrounding skin

A skin tag may be flesh-colored, pink, brown or darker than the surrounding skin.

Color alone cannot distinguish a skin tag from a tick because both can appear brown or dark.

It has been present for a long time

A bump that has remained in the same place for weeks, months or years is less likely to be a newly attached tick.

However, a long-standing skin growth should still be evaluated if it changes, bleeds, becomes painful or develops an unusual surface.

It has no separate attachment point

A skin tag grows from the skin itself. It does not have a distinct parasite body attached by mouthparts.

Nearby similar growths are present

Some people and animals have more than one skin tag or similar benign-looking growth.

Do not assume all bumps are harmless simply because several are present. A new or changing bump should be assessed appropriately.

Why Can an Engorged Tick Look Like a Skin Tag?

An engorged tick can become much larger and rounder than an unfed tick. Its expanded abdomen may look smooth, pale and skin-like.

Confusion is especially common when:

• The legs are hidden beneath the swollen body
• The tick is covered by hair or fur
• The attachment point is inside a skin fold
• The body is pale, grey or tan
• The tick is viewed only from above
• The lighting is poor
• The image is blurred or over-zoomed

Part the hair or fur completely and inspect the object from the side. Look for darker legs near the front and a separate body sitting above the skin.

Do not delay proper removal after you have clearly confirmed that the object is an attached tick.

How to Inspect the Bump Safely

Use a calm, careful visual check without pulling at the object.

1. Move into bright, even lighting.
2. Wash your hands before touching the surrounding area.
3. Part hair or fur completely around the bump.
4. Look at the bump from above and from the side.
5. Check for small legs near the front or sides.
6. Look for a separate oval or rounded body.
7. Inspect where the object meets the skin.
8. Compare it with nearby normal skin features.
9. Use magnification or the Tick Camera when helpful.
10. Seek professional advice if it remains unclear.

Do not use your fingernails

Scratching or scraping can damage a skin tag, mole, scab or other skin growth. It can also crush an attached tick.

Do not twist the bump

Twisting an unidentified bump can cause pain, bleeding and skin injury.

Do not cut it off

Never use scissors, nail clippers, a razor or another cutting tool on an unidentified bump.

Do not apply household substances

Do not cover a possible tick with petroleum jelly, oil, nail polish, glue or other household products.

Take a clear photograph

A sharp image taken in good lighting can help you compare the spot or show it to a healthcare professional or veterinarian.

Do not postpone removal of a clearly identified tick merely to obtain a perfect photograph.

Tick or Skin Tag on a Person

On human skin, both ticks and skin tags may appear around the neck, armpits, groin, waist or other skin folds.

Consider the following questions:

• Did the bump appear after outdoor activity?
• Does it have visible legs?
• Does it sit on top of the skin as a separate object?
• Is it attached at one small point?
• Has it become larger over a short time?
• Was it present before the possible tick exposure?

A healthcare professional should assess an uncertain bump when it is bleeding, painful, rapidly changing, unusually colored or located where inspection or removal cannot be performed safely.

Common areas for skin tags

Skin tags frequently develop where skin or clothing causes repeated friction, including the neck, armpits and groin.

These are also areas where ticks can be difficult to see, so location alone does not identify the bump.

Use previous photographs when available

An older photograph showing the same bump in the same location can suggest that it was present before the recent outdoor exposure.

Do not rely exclusively on photographs when the bump has changed or the image quality is poor.

Tick or Skin Tag on a Dog

Dogs can have ticks, nipples, warts, cysts, moles and various skin growths that may be mistaken for one another.

Part the fur completely around the bump and inspect the skin at its base.

Check for legs

A tick has legs near the front or sides. A canine skin tag does not.

Consider where the bump is located

Ticks are often found around the ears, face, neck, collar area, armpits, groin, paws and tail. Skin growths can occur in many of the same places.

Compare with the dog’s nipples

Nipples are arranged in two lines along the underside of the body. They can be mistaken for ticks, particularly beneath thick fur.

Do not pull at a bump until you have checked its position and appearance carefully.

Look for a stalk-like base

Some skin tags on dogs extend from the skin on a narrow stalk and may have a slightly irregular or wart-like surface.

Ask a veterinarian about changing growths

A veterinarian should assess a bump that grows rapidly, changes color, bleeds, becomes ulcerated, causes discomfort or cannot be identified confidently.

Tick or Skin Tag on a Cat

A small tick on a cat can resemble a skin bump, nipple, scab or piece of debris hidden in the coat.

Cats may not tolerate prolonged handling, so keep the inspection short and calm.

Part the fur completely

Use your fingertips or a comb to expose the skin around the entire object.

Look for a separate body

A tick sits above the skin and may have visible legs. A skin growth emerges directly from the cat’s skin.

Do not force the cat to remain still

Stop if the cat hisses, struggles, lashes its tail or attempts to scratch or bite.

Seek veterinary help when uncertain

A veterinarian should inspect the bump when it cannot be viewed safely, is close to the eye, lies deep inside the ear or appears inflamed or painful.

Could the Bump Be Something Else?

A tick and a skin tag are not the only possibilities. Other spots and growths may look similar.

Scab

A scab is dried material over healing skin. It may feel rough, crusted or irregular and has no legs.

Mole

A mole is part of the skin and may be flat or raised. It has no separate body or legs.

Wart

A wart may have an uneven, rough or cauliflower-like surface. Some warts are attached by a narrower base.

Nipple

Nipples can resemble ticks on dogs and cats, particularly when they are small or hidden by fur. They usually occur in a regular pattern along the underside.

Cyst or other skin lump

A cyst or growth may form beneath or within the skin rather than sitting on top of it.

Dirt or plant material

Dried dirt, burrs and seeds may become trapped in hair or fur. They are not attached through mouthparts and have no moving legs.

Another insect

A flea, beetle or other small insect may temporarily sit on the skin or become caught in fur. Ticks do not have wings and do not jump.

What Should You Do If It Is a Tick?

Once you have clearly identified an attached tick, remove it promptly and carefully.

Use clean fine-tipped tweezers or an appropriate tick-removal tool. Grasp the tick as close to the skin as possible and pull upward with slow, steady pressure.

Avoid squeezing or crushing the tick’s body.

How to Remove a Tick Safely

Clean the area afterward

Clean the attachment site and wash your hands after handling the tick.

Record the date and location

Note when and where the tick was found. A clear photograph can help document the tick and attachment site.

Monitor the person or pet

Watch the attachment site and general health. Contact a healthcare professional or veterinarian if concerning symptoms or changes develop.

Get help for sensitive locations

Seek professional assistance when the tick is near the eye, deep inside the ear, inside the mouth or in another place where removal cannot be completed safely.

What Should You Do If It Is a Skin Tag?

Do not cut, twist, tie off or attempt to remove a suspected skin tag yourself.

Many skin tags do not require treatment, but a healthcare professional or veterinarian should confirm the diagnosis when the growth is new, changing or unclear.

Leave it alone when it is not causing problems

A confirmed skin tag that is not irritated may not require removal. Follow the advice of the appropriate professional.

Watch for changes

Seek advice if the growth:

• Grows rapidly
• Changes color or shape
• Begins bleeding
• Develops an open or crusted surface
• Becomes painful or itchy
• Is repeatedly caught on clothing or equipment
• Causes a pet to lick, scratch or bite the area

Do not use home-removal products on pets

Human skin-tag products should not be used on dogs or cats. Ask a veterinarian to examine the growth.

Do not assume every stalk-like growth is harmless

Different skin conditions can have a similar appearance. A professional examination may be needed for a reliable diagnosis.

Common Mistakes When Comparing a Tick and Skin Tag

Looking only at the color

Ticks and skin tags can both appear brown, dark or flesh-colored. Color alone is not enough.

Expecting the tick’s legs to be obvious

Legs may be hidden beneath the body, hair, fur or a skin fold.

Pulling the bump to see whether it comes off

This can tear a skin tag, mole or other growth and may crush an attached tick.

Assuming a pale bump cannot be a tick

An engorged tick may appear grey, tan, pale brown or blue-grey.

Assuming every soft bump is a skin tag

A feeding tick can become smooth and rounded. Inspect the base and look for legs.

Relying only on touch

Both ticks and skin growths may feel like small raised bumps. Visual inspection is essential.

Using excessive digital zoom

Digital zoom may enlarge blur without revealing more detail. Use good lighting, steady the phone and move only as close as the camera can focus.

Cutting hair or fur too close to the bump

Scissors may injure the skin or cut the object. Part the hair or fur rather than cutting close to an unidentified lump.

Waiting too long after confirming a tick

Once an attached tick has been clearly identified and can be reached safely, remove it promptly using an appropriate method.
