Updated on April 10, 2026

Abnormal collections of glomus cells, called glomangiomas or glomus cell tumors, are benign clusters of bluish-purple nodules that are often painful and sensitive to pressure. Glomangiomas are benign but can be annoying, and patients may develop clusters in any part of the body.

What causes Glomangioma?

In most cases, the cause of glomangiomas are unknown. However, some may have a genetic component as they can be passed along from parents to their children.

What is a Glomangiomyoma?

Glomangiomyoma is the rarest variant, which accounts for less than 10% of all glomus tumors. It is histologically characterized by the gradual transition of the glomus cells into elongated, mature, smooth muscle cells.

What causes a glomus tumor?

The cause of a glomus jugulare tumor is unknown. In most cases, there are no known risk factors. Glomus tumors have been associated with changes (mutations) in a gene responsible for the enzyme succinate dehydrogenase (SDHD).

Can a glomus tumor be cancerous?

Malignant glomus tumor, or glomangiosarcoma, is a very rare mesenchymal neoplasm that, when seen, occurs in visceral organs. Despite having histologic features of malignancy, these tumors usually do not metastasize. However, when metastasis occurs, this disease is often fatal.

Why are glomus tumors so painful?

The cause is unknown and most glomus tumors occur in people between age 30 and 50. Like Wicker, many patients complain of temperature sensitivity and intense pain in one spot; some scientists speculate that the pain may be caused by nerve fibers that are present in glomus tumors.

Should glomus tumor be removed?

A glomus tumor is typically treated with surgical intervention. Because this condition can affect the patient’s quality of life, a definitive diagnosis is necessary to evaluate the extent of the condition. However, because this condition is benign, recurrence is uncommon.

Where do glomus tumors grow?

In the head and neck, glomus tumor tissue is found in the jugular bulb, middle ear, and carotid artery. Of these sites, tumors are most common in the jugular bulb, which is a region of the jugular vein positioned immediately below the middle ear. These glomus tumors may grow into the middle ear and brain.

How do you remove a glomus tumor?

How are Glomus Tumors treated? Surgical excision of the tumor is the only treatment modality. During a 15-minute outpatient procedure the nail is removed, an incision is made into the nail bed exposing the tumor, and the tumor is removed. The site is sutured closed and bandaged.

How do you treat glomus tumor?

The curative treatment of choice for symptomatic solitary glomus tumors is total surgical excision to minimize the rate of painful recurrence. There have been reports that laser and sclerotherapy may be effective in some cases of solitary glomus tumors however, complete excision is the best option.

Are glomus tumors hereditary?

Most glomus jugulare tumors develop by chance in individuals who have no family history of this condition.

How fast do glomus tumors grow?

Glomus tumors grow slowly and can only be detected by MRI years following the first appearance of the symptoms [6,7]. Subungual glomus tumors mostly occur in female patients [8], while for tumors located in other areas of the body, there is no sex predilection [3].

Can a glomus tumor grow back?

Once the tumor is completely removed, the patient does quite well and has no further problems. If the tumor is not completely removed, it can grow back and another surgery may be needed. Nail plate regrowth can be a problem, but is not common.

What is a subungual glomus tumor?

Glomus tumors are benign hamartomas arising from the glomus body, mostly occurring in the subungual region of the digits. A triad of excruciating pain, localized tenderness and cold sensitivity is the key to diagnosing these tumors.

Are glomus tumors rare?

Glomus tumors are rare, benign, vascular neoplasms arising from the glomus body. Although they can develop in any part of the body, they commonly do so in the upper extremities, most frequently subungual areas.

How common are glomus tumors?

Glomus tumors (also called paragangliomas) are a rare, slow-growing, and usually benign type of skull base tumor that often develop near the inner ear.

What is a subungual tumor?

Subungual exostosis, also known as Dupuytren exostosis, is an uncommon, solitary, benign bone lesion arising from the distal phalanx beneath the nail. Although it can occur at any age, it is predominantly found in young adults and adolescents, with females being affected twice as often as males.

What does glomus mean?

Definition of glomus : a small arteriovenous anastomosis together with its supporting structures.

What is benign tumor?

Listen to pronunciation. (beh-NINE TOO-mer) A growth that is not cancer. It does not invade nearby tissue or spread to other parts of the body.

Can a tumor be cured?

Treatment. There are no cures for any kinds of cancer, but there are treatments that may cure you. Many people are treated for cancer, live out the rest of their life, and die of other causes. Many others are treated for cancer and still die from it, although treatment may give them more time: even years or decades.

What percentage of paragangliomas are hereditary?

Common characteristics are: they grow slowly and they are benign. The prevalence of paragangliomas is approximately 1 to 30,000. About 10 to 50% of all paragangliomas are familial. Many subjects with genetic predisposition do not have phenotypic expression of the disease.

How is paraganglioma inherited?

Hereditary paraganglioma-pheochromocytoma is inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to increase the risk of developing tumors. An additional mutation that deletes the normal copy of the gene is needed to cause the condition.

Who can diagnose Subungual melanoma?

To correctly diagnose subungual melanoma, your doctor will need to conduct a biopsy. It will most likely be a punch biopsy, which is a procedure in which a tube-like instrument with a sharp end works like a cookie cutter to take a small sample. This small sample will be tested for melanoma.

What is the subungual region?

The subungual area includes the germinal matrix, nail bed, and dermis beneath the nail plate. This space also includes the bone of the distal phalanx. Because of the anatomic narrowness of the subungual space, any tumors arising from this space can erode into the distal phalanx of the digits and cause nail deformity.

What is subungual exostosis?

A subungual exostosis (SE) is a bony overgrowth that is permanently attached to the tip of the distal phalanx. Its pathology differs from osteocartilaginous exostoses in that it mainly involves the overgrowth of normal bone, which may present beneath the toenail or on the sides of the toe.
