How is glomus tumor treated?
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.
Is glomus tumor benign or malignant?
Glomus tumors originating from the glomus body in the dermis account for less than 5% of all diagnosed tumors in the hand and almost all are benign. Malignant glomus tumors—also termed glomangiosarcomas—are exceedingly rare2,3 and are more common in the lower extremity.
How rare is a glomus jugulare tumor?
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.
Should glomus tumor be removed?
A bloodless field is essential to allow for meticulous removal of the tumor. Periungual glomus tumors will frequently depress the bone of the distal phalanx and may be adherent within the periosteum. When this occurs, as in our case, meticulous curettage of the bone may prevent recurrence.
What is a glomus Tympanicum?
Glomus Tympanicum – About Glomus tympanicum tumors are tumors called paragangliomas that arise in the middle ear (behind the ear drum). These tumors are almost always benign. Symptoms typically involve hearing one’s heart beat and hearing loss.
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.
What is the characteristic symptom of a glomus tumor?
The typical clinical symptoms of glomus tumors are pain, tenderness, and sensitivity to temperature change, and the presence of these clinical findings is helpful in diagnosis. However, the tumors often pose diagnostic difficulty because of variations in presentation and the nonspecific symptoms of glomus tumors.
Are glomus tumors hereditary?
Most glomus jugulare tumors develop by chance in individuals who have no family history of this condition.

What does a glomus tumor look like?
Glomus Tumors usually present as a small, firm, reddish-blue bump underneath the finger nail. These lesions are usually quite small, less than 7mm in diameter. They can be extremely painful, are sensitive to temperature change, and tender on palpation.
What causes glomus Tympanicum 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).
How common is glomus Tympanicum?
Glomus tympanicum is the most common primary neoplasm of the middle ear and the second most common tumour of the temporal bone [1]. Although histologically benign, glomus tympanicum is slow growing, locally destructive, spreading along paths of least resistance.
Can a glomus tympanicum tumor cause hearing loss?
Glomus tympanicum tumors arise from the tympanic nerve (Jacobson’s nerve) in the middle ear and may cause hearing loss and pulsatile tinnitus. Barry E. Hirsch, in Operative Otolaryngology: Head and Neck Surgery (Second Edition), 2008
What kind of tumor is glomus tympanicum paraganglioma?
Glomus tympanicum paragangliomas are considered type A tumor, as they are limited to the middle ear cavity. Surgical resection is the treatment of choice 4 . 1. Lee KY, Oh YW, Noh HJ et-al. Extraadrenal paragangliomas of the body: imaging features.
Where are glomus tumors located in the ear?
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. Tumors originating in glomus cells of the middle ear are called glomus tympanicum tumors.
What kind of surgery is needed for glomus tympanicum?
The surgical approach for glomus tympanicum tumors is dictated by the size of the lesion. Small tumors limited to the mesotympanum and hypotympanum without involvement of the jugular bulb are removed through a transcanal approach. Larger lesions usually require a postauricular approach to provide greater exposure.
