Objective Glomus jugulare tumors, or tympanojugular paragangliomas, are rare, highly vascularized skull base tumors originated from paraganglion cells of the neural
crest. With nonabsorbable embolic agents, embolization combined with surgery has become the norm. The authors assess the profile and outcome...
Paragangliomas are rare, benign and slow-growing neuroendocrine tumors that can
arise from the adrenal medulla (85–90%) or from the extra-adrenal paraganglia.
In the central nervous system (CNS), they can be found at several sites, but more often
at the cauda equina and filum terminale region, where th...
Paragangliomas are rare, encapsulated, benign neuroendocrine tumors that can arise from the adrenal medulla or extra-adrenal paraganglia. Extra-adrenal paragangliomas may develop a gangliocytic component with ganglion cells (Gangliocytic paragangliomas). Nearly 25%of cauda equina paragangliomas are gangl...
Resumen El paraganglioma (PG) es una neoplasia infrecuente originada de las células paraganglionares, embriológicamente derivadas de la cresta neural. Se localizan en la cabeza, base de cráneo, cuello, mediastino, abdomen y pelvis. La mayor parte de los PG muestran un curso clínico benigno, sin embar...
ABSTRACT Purpose As a rare bladder tumor, paraganglioma of the urinary bladder (PUB) is frequently misdiagnosed as bladder cancer, particularly for the non-functional type. To date, transurethral resection remains a controversial treatment for non-functional PUB. This study aimed to identify the clinic...

Malignancy must be considered in the management of adrenal lesions, including those incidentally identified on imaging studies. Adrenocortical carcinomas (ACCs) are rare tumors with an estimated annual incidence of 0.7-2 cases per year and a worldwide prevalence of 4-12 cases per million/year. However, a...

SUMMARY Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of a non-pituitary ACTH-secreting tumor leading to Cushing's syndrome. Only a few cases have been reported previously as causing ectopic ACTH related to paraganglioma. Herein, we pre...

CONTEXT: Protein marker positivity can assist in the definition of the therapeutic approach towards head and neck paragangliomas. The establishment of the therapeutic approach should incorporate the results of such an investigation. OBJECTIVE: To establish criteria for benignancy and malignancy of vagal ...

Treze casos de paraganglioma em regiäo de cabeça e pescoço foram estudados e seus diferentes aspectos clínico-patológicos foram analisados. Ocorreu com maior freqüência na quarta década de vida, com discreta predominância no sexo feminino. A sintomatologia apresentada pelos pacientes variou com ...
