متن کاملBilateral Carotid Paraganglioma: Surgery and Radiotherapy
BACKGROUND Paragangliomas are relatively rare vascular tumors that develop from the neural crest cells of carotid bifurcation. They usually present as slow-growing, painless unilateral neck masses; bilateral presentation is rare and is mostly associated with familial forms. Bilateral total resection is not always possible for high-grade bilateral tumors, and radiotherapy is a good alternative, ...
متن کاملLaryngeal Paraganglioma: A Diagnostic Challenge
Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...
متن کاملBilateral pheochromocytoma/intra-adrenal paraganglioma in von Hippel-Lindau patient causing acute myocardial infarction.
A 26-year-old male presented to the emergency department complaining of obstipation, severe headache and abdominal pain. An autopsy revealed bilateral pheochromocytoma and acute myocardial infarction. The tumor cells showed positive immunoreactivity of both chromogranin A and synaptophysin and were negative for adrenocortical markers such as SF-1, c17, scc, 3-HSD as well as SDHB, suggesting a ...
متن کاملCandidate gene mutation analysis in bilateral adrenal pheochromocytoma and sympathetic paraganglioma.
Pheochromocytomas (PCCs) are rare tumors that arise from chromaffin tissue in the adrenal medulla, but can also occur in the abdomen outside the adrenals and are then called sympathetic paragangliomas (sPGLs). According to the literature, between 15 and 25% of apparently sporadic adrenal PCC and sPGL are caused by germline mutations in RET, von Hippel-Lindau disease (VHL), succinate dehydrogena...
