A glomus tumor is a rare, non-cancerous growth that comes from the glomus body, a skin part involved in regulating temperature.

They usually show up under the nails (subungual), on fingers, or in feet.

Symptoms can include pain in one area, sensitivity to temperature, tenderness, and sometimes a bluish or reddish spot.

The exact reason isn’t known, but they come from parts of the glomus body in skin or soft tissues.

Identification may require a physical exam, imaging like MRI or ultrasound, and sometimes a biopsy.

Most glomus tumors are not cancerous, but a small number can become malignant.

Treatment typically involves surgically removing the tumor.

Surgery is usually needed to relieve symptoms and stop the tumor from coming back.

Local or regional anesthesia is generally used, depending on where the tumor is.

Recovery is usually fast, with many returning to normal activities in a few weeks.

Yes, they can return if the tumor is not fully removed.

Risks include infection, bleeding, and the chance of the tumor returning if not completely taken out.

There are very few nonsurgical options; complete surgical removal is the best treatment.

There is no strong proof suggesting that glomus tumors are passed down through families.

Possible outcomes include ongoing pain, issues with daily activities, and very rarely, cancer development.

Follow your surgeon's guidelines before surgery, which may include changing medications and fasting.

Some scarring might occur, but usually, it's minor due to the small incision.

Most often in extremities, they can theoretically appear anywhere glomus bodies are present.

An MRI can show the size, location, and how extensive the tumor is.

These tumors tend to be painful, particularly with temperature changes or pressure.

Lifestyle changes won't remove the tumor, but avoiding extreme temperatures might ease pain.

Home remedies aren't usually effective; surgical intervention is often necessary for pain relief.

Light use may be possible within days, with full activity returning gradually as healing occurs.

They are generally small, often less than 1 cm in size.

Biopsy not always needed, especially if imaging and clinical signs clearly show a glomus tumor.

Nail growth usually not affected in the long term, though some temporary changes may happen during healing.

Diagnosis depends on clinical features, imaging, and sometimes a tissue examination.

Yes, subungual glomus tumors can change color and might have a visible lesion under the nail.

They can happen at any age but are more often seen in adults and a bit more in women.

No known prevention exists, as the cause is not completely understood.

Follow-up visits to check healing and look for any signs of returning tumors.

Glomus tumors come from glomus bodies and are painful, while ganglion cysts are usually painless, fluid-filled sacs.

Medications might ease pain temporarily, but they don’t solve the tumor issue.

It starts from a part of the vascular system, but usually does not impact overall circulation.

Some initial pain and swelling, with most discomfort going away as healing occurs.

There’s no proof that alternative treatments can effectively handle glomus tumors.

Rare, but having multiple lesions can happen, especially with glomangiomatosis.

It refers to a similar type of lesion with more visible vascular parts and may appear multiple times.

Localized pain, mainly with temperature sensitivity, is a major sign of a glomus tumor.

While imaging helps, smaller tumors can sometimes be hard to spot.

They usually grow slowly, often taking months or years.

They can suspect a glomus tumor based on symptoms and check-ups, but a specialist is often needed for a clear diagnosis.

Most removals are done as outpatient procedures, so no hospital stay is usually required.

Coverage varies by insurance plan, but it's generally seen as medical not cosmetic.

Unique pain feelings, temperature sensitivity, and imaging help to differentiate it from other problems.
