A Case of Endoscopic Treatment of Multiple Carcinoid Tumors in Stomach / 대한소화기내시경학회지

ABSTRACT

Multiple carcinoid tumors in stomach are very rare tumors and associated with pernicious anemia, chronic atrophic gastritis and Zollinger-Ellison syndrome. These are believed to be due to hypergastrinemia, resulting in chronic stimulation of enterochromaffine-like (ECL) cells, leading to hyperplasia, metaplasia and ultimately neoplasia. The carcinoid tumor is potentially malignant, even though it may grow slowly, so the treatment of choice must be endoscopic lumpectomy or surgical gastrectomy. The prognosis depends on the site of the tumor and its size. Most carcinoid tumors are less than 1 cm in size and metastasis is uncommon but metastasis in tumors with size over 2 cm is common. A case of multiple carcinoid tumors in stomach, which was successfully removed by endoscopy, is herein reported.
