The glomus tumor is a rare benign neoplasm that arises from the neuroarterial structure called a glomus body1, which accounts for 1 % to 4.5 % of tumors in the hand. The normal glomus body is located in the stratum reticulare throughout the body, but is more concentrated in the digits6.
How common are glomus jugulare tumors?
Glomus jugulare tumors are rare, occurring in one in every 1.3 million people each year. These tumors are much more common in women than men and tend to arise between the ages of 40 and 70.
Is glomus tumor curable?
The only real treatment for a glomus jugulare tumor is surgery. Even if a tumor is small and not causing severe symptoms, it may need to be removed. If it isn’t removed, the tumor will continue to grow slowly and cause more problems as it gets bigger.
Where are glomus tumors most commonly found?
Glomus tumors, or paragangliomas, are slow-growing, usually benign tumors in the carotid arteries (major blood vessels in your neck), the middle ear or the area below the middle ear (jugular bulb). Glomus tumors are most often benign; however, they can cause significant damage to surrounding tissues as they grow.How do you know if you have a glomus tumor?
Symptoms of glomus tumors depend on their location: middle ear, jugular bulb, deep neck, or carotid artery. Your ear may perceive the flow of blood as a pulsating sound or ringing. Bleeding from the ear. Hearing loss — the growing mass may interfere with sound transmission.
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.
Are glomus tumors hereditary?
Most glomus jugulare tumors develop by chance in individuals who have no family history of this condition.
What causes a glomus Tumour?
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).Are glomus tumors painful?
Glomus tumors are painful subungual lesions. They produce a throbbing or lancinating local discomfort, cold-sensitivity, and severe pain following minor trauma. The diagnosis is confirmed by histology, but the clinical diagnosis is highly suggestive. Complete excision will usually relieve pain.
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.
Article first time published onCan 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.

Do glomus tumors spread?
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.
Can glomus tumors 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 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.
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.
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.
How rare is a paraganglioma?
Paraganglioma is rare and it is estimated that only 2 people out of every 1 million people have paraganglioma. It is most often found in people aged 30 to 50 years old.
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.
What is a tumor of the nail bed called?
Onychomatricoma is a tumor of the nail matrix which often presents with alterations in the nail plate while the tumor itself is concealed beneath the nail plate. It is a benign, biphasic fibroepithelial tumor which has to be differentiated from other subungual and periungual tumors.
What is a giant cell lesion?
A giant cell tumor is a rare, aggressive non-cancerous tumor. It usually develops near a joint at the end of the bone. Most occur in the long bones of the legs and arms. Giant cell tumors most often occur in young adults when skeletal bone growth is complete. The exact cause of giant cell tumors remains unknown.
What is an aural glomus tumor?
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. Without treatment, they can harm surrounding tissue, damage nerves, and cause other serious problems.
What does glomus mean?
Definition of glomus : a small arteriovenous anastomosis together with its supporting structures.
What is neurofibroma?
Neurofibromas are benign (noncancerous) tumors that grow on nerves in the body. Most neurofibromas occur in association with a genetic disorder. Solitary neurofibromas can also occur in otherwise healthy people; these are called sporadic neurofibromas.
What causes tumors in fingers?
Finger lumps commonly occur at the joint area and are indicative of osteoarthritis and other arthritis-related conditions. Traumatic causes of finger lumps range from bug bites to severe injuries. Both benign and malignant tumors of the skin, soft tissues, or bone can appear as a finger lump.
What is the jugular bulb?
The jugular bulb (JB) is the confluence of the lateral venous sinuses situated in the jugular fossa. It drains extracranially to the internal jugular vein as it passes through the jugular foramen of the posterior cranial fossa. The precise location of this structure within the temporal bone is variable.
Who treats glomus Jugulare?
Alpha-blockers and beta-blockers are useful for tumors secreting catecholamines. They are usually administered for 2-3 weeks before embolization and/or surgery to avoid potentially lethal blood pressure lability and arrhythmias.
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.
What are benign Tumours?
Benign Tumors. Benign tumors are those that stay in their primary location without invading other sites of the body. They do not spread to local structures or to distant parts of the body. Benign tumors tend to grow slowly and have distinct borders. Benign tumors are not usually problematic.
