A Polyp-like Carcinoid Tumor of Rectum, Small Size and Unusual Location in Chareongkrung Pracharak Hospital
ثبت نشده
چکیده
A 56-years-old man with a small rectal carcinoid tumor without carcinoid syndrome was admitted at Chareongkrung Pracharak Hospital with rectal bleeding. Proctoscopy revealed a small 7-mm rectal polyp, at 6 cm above the dentate line. Histology was diagnostic of a carcinoid tumor without atypical histopathologic feature or invasion into the muscularis propria . Immunohistochemical study was positive for NSE and synaptophysin (neuroendocrine marker) and non-reactive for argyrophil silver granules. The tumor did not express p53 antigen and was negative for Ki 67, suggesting a low malignant potential and a low metastatic activity. Total colonoscopy up to the ileocecal valve with subsequent polypectomy was carried out. There was neither tumor recurrence nor distant metastasis at 1-year follow-up.

متن کاملCarcinoid tumors.
Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that often are indolent and may not become clinically apparent until there has been metastatic spread or evidence of carcinoid syndrome. Recent evidence has revealed that the overall incidence of carcinoid tumors has been steadily increasing, and although the disease was thought to be relatively benign, it is now considered one of...
