Paraganglioma de corpo aórtico e carotídeo / Aortic and carotid body paraganglioma / Paraganglioma de cuerpo aórtico y carótida

Os paragangliomas são neoplasias de células neuroendócrinas (Paraneurônios) do sistema parassimpático (Paraganglia), e ocorrem normalmente no corpo aórtico (base do coração) e carotídeo (pescoço). São tumores raros, frequentemente benignos, que podem raramente metastatizar. Raças braquiocefálicas e animais que vivem em elevadas altitudes são mais predispostos ao desenvolvimento de paragangliomas. Esta revisão bibliográfica objetiva-se descrever as manifestações clínicas, etiopatogenia, formas de diagnóstico e tratamento dos paragangliomas.

The paraganglioms are neoplasms of neuroendocrine cells (Paraneurons) of the parasympathetic system (Paraganglia). Normally occur on the aortic (base of heart) and carotid (neck) bodies. They are rare tumors, frequently beginners and its rarely able to metastasize. Braquicephalics breeds and animals that live in high altitudes are more predisposed to developing paraganglioms. This bibliographic review describes clinical manifestation, etiopathogeny and types of diagnosis and treatment of the paraganglioms.

Two Cases of Endoscopic Resection of Submucosal Tumor of the Minor Papilla / 대한소화기내시경학회지

Tumors of the minor papilla are very rare and these tumors have generally been known as neuroendocrine tumors such as carcinoid tumor and somatostatinoma. As these are mostly submucosal tumors, their diagnosis is difficult by just performing endoscopic forceps biopsy, but diagnosis is possible by surgery or endoscopic resection. EUS and ERCP is an essential tool for the diagnosis of these tumors, and abdominal CT or MRI is also useful because there is the possibility of malignant tumors such as carcinoid tumor. For our present two cases, screening endoscopy revealed the polypoid lesion of the minor papilla. EUS disclosed that the submucosal tumor was limited to the submucosal layer and no abnormality was found from the abdominal CT and ERCP. Herein, we performed endoscopic resection for making the diagnosis and treatment. Histologically, these 2 tumors were diagnosed as ectopic pancreas and gangliocytic paraganglioma, respectively.
