 A 58-year-old woman was referred to our hospital, because of a polypoid lesion in the rectum. Radiography and colonosopy revealed the lesion to be a semispherical, smooth tumor with a shallow depression, measuring 10 mm in diameter. The tumor was removed using the endoscopic mucosal resection technique. Histologicl examination of the resected tumor revealed the lesion to be a classical cacinoid tumor restricted to the submucosal layer. At that time, the patient was diagnosed by ultrasonography as having two liver nodules in the liver. Because the hepatic nodules increased in size and number during the subsequent three years, they were resected by surgery. Histologically, the hepatic nodules were composed of carcinoid cells . Although classical carcinoid of the rectum is presumed to have low malignant potential, our case suggests that careful considerations as regards the choice of therapy and intensive follow-up are deemed necessary in cases of rectal carcinoid tumors.
