3. Carcinoma de células não escamosas da laringe: achados clínicos e de imagem
Resumo Introdução O carcinoma de células escamosas é a neoplasia laríngea mais comum, representa aproximadamente 95% de todas as neoplasias malignas da laringe. No entanto, vários outros tumores benignos e malignos, e doenças inflamatórias, podem afetar a laringe. Objetivo O objetivo deste estudo é analisar os achados clínicos e de imagem de neop

4. Simultaneous Quantification of Plasma Catecholamines and Metanephrines by LC-MS/MS
The quantification of the low levels of catecholamines and metanephrines in biological fluids is important for clinical screening of pheochromocytoma/paraganglioma and diagnosis of overtraining syndrome in athletes. We introduce a novel, accurate and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for simultaneous quantification of

6. Non-functional paraganglioma of urinary bladder managed by transurethral resection
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 clinical features, pathological characteristics, prognosis, a

7. Pheochromocytoma and paraganglioma: implications of germline mutation investigation for treatment, screening, and surveillance
ABSTRACT Objective Paraganglioma (PGL) and pheochromocytoma (PCC) are rare neuroendocrine tumors that were considered to be predominantly sporadic. However, with the identification of novel susceptibility genes over the last decade, it is currently estimated that up to 40% of cases can occur in the context of a hereditary syndrome. We aimed to characterize

8. Primary malignant tumors of the adrenal glands
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 much higher incidence of these tumors (>15 times) has

9. Paraganglioma do osso temporal: 15 anos de experiência
Resumo Introdução Paragangliomas do osso temporal (POT) são tumores benignos derivados de células da crista neural localizados ao longo do bulbo jugular e do plexo timpânico. Em geral, a excisão cirúrgica, a radioterapia e os protocolos de acompanhamento com estudos por imagem são as principais modalidades de conduta para o POT. Objetivo Apresentar

10. The clinical genetics of phaeochromocytoma and paraganglioma
ABSTRACT Phaeochromocytoma and paraganglioma are rare catecholamine-producing tumours, recognised to have one of the richest hereditary backgrounds of all neoplasms, with germline mutations seen in approximately 30% of patients. They can be a part of genetic syndromes such as MEN 2 or Neurofibromatosis type 1, or can be found as apparently sporadic tumours.

11. A rare case of ectopic ACTH syndrome originating from malignant renal paraganglioma
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 present a case of Cushing’s syndrome, in who was prove

12. Presentation and surgery outcomes in elderly with pheocromocytoma: a comparative analysis with young patients
ABSTRACT Purpose: To evaluate the presentation and early surgical outcomes of elderly patients undergoing adrenalectomy for phaeochromocytoma. Patients and Methods: A retrospective search was performed of our adrenal disorders database for patients who underwent surgery for phaeochromocytoma or paraganglioma between 2009 and 2014. Patients >60 years old we
