Reporte de caso de feocromocitoma bilateral asociado a mutación del gen TMEM127. Primer caso chileno

Rev. med. Chile; 150 (8), 2022
Up to 40% of Pheochromocytoma/paraganglioma syndromes are associated with germline mutations. Therefore, they are considered familial and heritable. We report a 65 year old woman with hypertension, bilateral adrenal nodules found in the CT scan and elevated urinary metanephrines. Her genetic testing show...

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 con...

What determines mortality in malignant pheochromocytoma? - Report of a case with eighteen-year survival and review of the literature

SUMMARY Pheochromocytoma (PCC) is a tumor derived from adrenomedullary chromaffin cells. Prognosis of malignant PCC is generally poor due to local recurrence or metastasis. We aim to report a case of malignant PCC with 18-year survival and discuss which factors may be related to mortality and long-term s...

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 t...

Manejo clínico y quirúrgico de los feocromocitomas y paragangliomas
Clinical and surgical management of pheochromocytomas and paragangliomas

Los feocromocitomas y paragangliomas (Feo/PGL) son tumores neurendocrinos raros con diferentes presentaciones clínicas, asociados a alta morbimortalidad. Reconocer los signos y síntomas es el paso diagnóstico inicial. Las metanefrinas fraccionadas urinarias tienen una excelente sensibilidad y especifi...
