A CASE OF POORLY DIFFERENTIATED ADENOCARCINOMA OF THE CECUM DETECTED ENDOSCOPICALLY IN AN EIARLY STAGE

Abstract

We present a rare case of poorly differentiated adenocarcinoma of the cecum detected endoscopically in an early stage. A58-year-old man was admitted because of colonic polyps pointed out by his home doctor.Endoscopy revealed a slightly depressed eszon, rneasuring 9 mm in dialneter, associated withredness in the cecum. This lesion was diagnosed as an early cecal cancer invadirlg thesubmucosal layer, and ileocecal resection with regional lymph node dissection was thus performed. Histological findings of this tumor shQwed poorly differentiated adenocarcinoma invadingthe submucosal layer without lymphatic and venous invasion, and lymph node metastasls. Furthermore, this tumor was not associated with adenoma around carcinoma.
