glomus tumor การใช้

• Glomus tumors do not arise from glomus cells, but paragangliomas do.
• Nonchromaffin paragangliomas are issued from glomus cells, also known as glomus tumors.
• The exact incidence of glomus tumors is unknown.
• Glomus tumors are modified smooth muscle cells that control the thermoregulatory function of dermal glomus bodies.
• Malignant glomus tumors, or glomangiosarcomas, are extremely rare and usually represent a locally infiltrative malignancy.
• Histologically, glomus tumors are made up of an afferent arteriole, anastomotic vessel, and collecting venule.
• Glomus tumors were first described by Hoyer in 1877, while the first complete clinical description was given by Masson in 1924.
• Such tumors in the middle ear go by a variety of names, but are most commonly referred to as glomus tumors or paragangliomas.
• A few cases of malignant glomus tumors have been reported; however, they are usually only locally invasive, and metastases are exceedingly rare.
• As stated above, these lesions should not be confused with paragangliomas, which were formerly also called glomus tumors in now-antiquated clinical usage.
• Another report of a malignant glomus tumor with metastases is that of Watanabe et al ., who reported a cutaneous malignant glomus tumor with widespread metastases.
• Another report of a malignant glomus tumor with metastases is that of Watanabe et al ., who reported a cutaneous malignant glomus tumor with widespread metastases.
• Brathwaite et al . in 1996 reported widespread metastases of a malignant glomus tumor involving the skin, lungs, jejunum, liver, spleen, and lymph nodes.
• In one report, a patient with more than 400 glomus tumors had thrombocytopenia as a result of platelet sequestration ( i . e ., Kasabach-Merritt syndrome ).
• A few other cases of malignant glomus tumors have been reported in the literature usually occur in the older age group, and have been described at several locations, primarily the soft tissues and gastrointestinal tracts.
• As a neurologist, he treated conditions of the ear and skull base including hearing loss, ear infections, facial palsy, dizziness and skull base tumors such as acoustic neuromas ( vestibular schwannomas ) and glomus tumors.
• Malignant glomus tumors have been subdivided into three categories based on their histologic appearance : locally infiltrative glomus tumors ( LIGT ), glomangiosarcomas arising in benign glomus tumors ( GABG ), and glomangiosarcomas arising de novo ( GADN ).
• Malignant glomus tumors have been subdivided into three categories based on their histologic appearance : locally infiltrative glomus tumors ( LIGT ), glomangiosarcomas arising in benign glomus tumors ( GABG ), and glomangiosarcomas arising de novo ( GADN ).
• Malignant glomus tumors have been subdivided into three categories based on their histologic appearance : locally infiltrative glomus tumors ( LIGT ), glomangiosarcomas arising in benign glomus tumors ( GABG ), and glomangiosarcomas arising de novo ( GADN ).
• A "'paraganglioma "'is a rare metastases . " Paraganglioma " is now the most-widely accepted term for these lesions, that have been also described as : glomus tumor, chemodectoma, perithelioma, fibroangioma, and sympathetic nevi.
