A Case of undifferentiated type gastric mucosal cancer, type IIc, with lymph node metastasis

Abstract

A 50-year-old woman who was pointed out an abnormality by gastric mass survey in November 1999, visited our center and received upper GI endoscopy. Endoscopic examination revealed a slightly discolored and depressed lesion with tapering of the fold in the greater curvature of the middle body. The pathological diagnosis was undifferentiated type gastric cancer. Gastrointestinal radiologic examination showed an irregular depressed lesion with tapering of the fold in the greater curvature of the middle body. We diagnosed undifferentiated type gastric mucosal cancer, so subtotal gastrectomy was performed. The lesion was 25×18mm in size and histopathological examination revealed the signet-ring cell carcinoma, partly showing adenocarcinoma microtubulare, limited to the mucosal membrane and lymphatic permeation was slightly suspected. Lymphnode metastasis was recognized in microscopic findings. In conclusion, it seems that the treatment for like this case requires circumspection because there is a possibility that only partial resection is not enough.
