Abstract
A case of the small intestinal carcinoma which is rare in the alimentary tract was reported in this paper. A 35-year-old man was admitted to our institute May 19th 1975, complaining of vomitting and weight loss. Radiologic examination of upper G-I tract revealed a tubelike stenosis with marked dilatation of the third portion of the duodenum. Roentgenological impression was a malignant tumor of the small intestine, but differentiation from a localized ulcerative disease was necessary. Endoscopic examination by small intestinal f iberscope (SIF-B, Olympus) also showed annular constriction with epithelial irregularity of its margin, which strongly impressed malignancy. Histologic diagnosis of biopsy specimen was reported as signet ring cell carcinoma. Cytodignosis by aspiration under direct vision was signet ring cell carcinoma too. The patient underwent operation on June 5th 1975 Histological studies of the resected material exactly coinsided with preoperative diagnosis.
