Wat is Glomus?
Glomus-caroticum-tumor Het glomusorgaan zit in de splitsing van de halsslagader en meet de zuurstofspanning in het bloed. Er kan sprake zijn van een glomus-caroticum-tumor aan één kant van de hals, maar het kan ook aan beide kanten tegelijk voorkomen.
What is a glomus tumor?
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.
Where are glomus apparati found?
While they are located all over the body, glomus apparati are found in higher concentrations in the fingers and toes. Abnormal growth of a glomus body results in Glomus Tumors. Glomus Tumors usually occur in people 20 to 50 years of age but are more frequent in young adults.
How common are glomus tumors in young adults?
Abnormal growth of a glomus body results in Glomus Tumors. Glomus Tumors usually occur in people 20 to 50 years of age but are more frequent in young adults. More common in women, 70% of Glomus Tumors present in the hand with the clear majority occurring underneath the nail bed. Most of the nodules are solitary but can occur in clusters.
What are the treatment options for glomus tumor?
MRI and CT scan are useful for detecting the lesions in the soft tissues, but for glomus tumors, MRI is not normally advised. CT scan shows non-specific subungual mass. Surgical excision is the only option for curing glomus tumor. The process is not a tough affair, and takes a 15-30 minutes outpatient procedure.
Een glomus tumor is een zeldzame kleine tumor. Wanneer er in een glomuslichaampje cellen gaan woekeren, ontstaat een glomustumor (angioneuroma). De glomustumor is blauwrood van kleur en zit meestal op de vingertoppen en kan ook onder het nagelbed voorkomen.
What is the prognosis of paraganglioma?
Patients with a small paraganglioma that has not spread to other parts of the body have a five-year survival rate of about 95%. Patients with paraganglioma that has grown back (recurred) or spread to other parts of the body have a five-year survival rate between 34% and 60%.
Can paraganglioma spread to other parts of the body?
The nerve cells involved in paraganglioma are part of the peripheral nervous system, meaning the part of the nervous system outside of the brain and spinal cord. These tumors can also be called extra-adrenal pheochromocytomas. Approximately 35-50% of paragangliomas may spread to other parts of the body. How common is paraganglioma?
What are the treatment options for paraganglioma?
Surgery: Once paraganglioma is diagnosed, you may have surgery to remove the tumor. Sometimes surgery is not an option, in which case, your doctor will discuss other options with you. Radiation therapy: Radiation therapy can be used to slow the tumors from growing and to help relieve symptoms.
How do you know if you have paraganglioma?
If Paraganglioma is suspected, then the doctor may prescribe a battery of tests in order to confirm the disease condition. The doctor may begin with collecting urine over a period of 24 hours and sending it for analysis to look for presence of any excessive adrenaline or noradrenaline secretions.
