Glomus tumours
Pericytic / perivascular neoplasms have traditionally been dominated by haemangiopericytoma. However, it is now recognized that the latter diagnostic category subsumes a wide variety of tumour types which share the presence of thin-walled branching blood vessels. If such lesions are otherwise classified, there remains only a small group of spindle cell lesions designated as haemangiopericytoma,...

Glomus tumours involving the middle ear and the cerebellopontine angle are reported with emphasis on audiological findings. Magnetic resonance imaging (MRI), angiographic and pathological results are presented. Audiological tests, including impedance audiometry, evoked otoacoustic emissions and auditory brainstem responses, are valuable in evaluation of the effect of glomus tumours on the audit...

Greater susceptibility of the subjects to these types of malignancies is thought to be the result of genetic mutations in highly penetrant genes transmitted as autosomal dominant traits. Mutations in such susceptibility genes result in familial predisposition to developing a characteristic spectrum of diseases (collectively known as Hereditar...
متن کاملFirst experiences with genetic counselling based on predictive DNA diagnosis in hereditary glomus tumours (paragangliomas).
Hereditary glomus tumour (MIM 168,000) or paraganglioma (PGL) is a slowly progressive disorder causing benign tumour growth predominantly in the head and neck region. Though benign in nature the tumours can lead to severe morbidity. Inheritance of PGL is autosomal dominant and is strongly modified by genomic imprinting; only a paternally transmitted PGL gene leads to symptoms. A gene for PGL ha...

The first description of this tissue were probably by Valentin (1840), who described his 'ganglia tympanica', and Krause (1878), his 'glandula tympanica'. Both writers described ganglionic-like tissue, but the credit for recognizing the histological relationship to the caro...
