Abstract
A case which is reported here for gastric carcinoid showing multiple polyps on the body of the stomach is a 58 years old, housewife. She had been treated for cardiomegaly for 8 years and also suffered from epigastric fullness for 4 years. Two years before operation, an X-ray examination at the mass screening for gastric cancer revealed gastric polyposis. Therefore she was ref f erred to Niigata Cancer Center following X-ray exams. Endoscopic examination revealed gastric polyposis on the body and biopsy specimens from polyps show-ed benign polyps. She had been followed up endoscopiccaly every 4 months with a diag-nosis of gastric polyposis. At the third examination, carcinoid tumor was suspected with biopsy specimens taken from one of these polyps. To confirm the diagnosis, endoscopic polypectomy for the largest polyp was performed to show the typical appearance of carci-noid tumor. In this patient biochemical examination for amines in the serum and urine showed nor-mal value including 5-HIAA and serotonine. After confirmation of the histological and biochemical examination, surgical operation was peformed. In the stomach 19 polyps all of which showed submucosal tumor on the body were seen. Carcinoid tumor proliferated mainly in the submucosal layer and formed submucosal tumor. These 19 tumors were connected with invaded carcinoid cells. The diameter of the largest one is 1.0 cm and it is the smallest tumor among the reported cases with the metastasis to the other organs.
