  • Look Inside

 A 60-year-old female was admitted to the Dept. of Surgery, Cancer Institute Hospital for the treatment of IIc type early gastric cancer which was first detected during a screening examination by direct radiography. Endoscopic examination with biopsy disclosed signet ring cell carcinoma. Detailed radiographic examination which was carried out after admission delineated a localized mucosal abnormality which consisted of an irregular depression with rough granularity in the posterior wall of the gastric body. Endoscopic examination revealed an area of discoloration in which redness and faintly whitish mucus were scattered. No capillary pattern was observed in the discolored area. However, even chromoendoscopy with indigocarmine could not delineate the whole lesion clearly. Pylorus preserving surgery was performed after the cancer-negative mucosa proximal to the lesion was confirmed by the India ink injection method. On the resected specimen, the lesion was seen as a mucosal depression consisting of nodular granularity and surrounding discoloration. Its border was poorly defined, and could not even be recognized macroscopically. Histologically, the lesion was diagnosed as type IIc simulating type IIb (Ul-II grade of ulceration), poorly differentiated adenocarcinoma (por2) limited to the mucosal membrane, measuring 30×25 mm.
