A CASE REPORT OF GASTRIC CANCER SIMULATING SUBMUCOSAL TUMOR

Abstract

A case of advanced gastric cancer showing the features of submucosal tumor and with no definite diagnosis before surgery is reported. The patient was a 44-years-old female with a presenting complaint of epigastralgia; a submucosal tumor-like lesion with ulceration on the posterior wall of the gastric angular region was detected. Histological examination of this lesion by means of endoscopic biopsy and boring biopsy after strip biopsy suggested a group I lesion, but possibility of a malignant lesion was also considered. Therefore, a subtotal gastrectomy was performed. After the operation, pathological examination revealed a signet-ring cell carcinoma with invasion to SS and lymphnode metastasis. Fifty-four cases of gastric cancer simulating submucosal tumors have been reported in Japan. But cases in which the chief component of the protrusion is collagenous fiber are very rare.
