EARLY GASTRIC CANCER OF TYPE IIc ORIGINATED ON THE MUCOSA ON SUBMUCOSAL TUMOR (LIPOMA)

Abstract

A 68-year-old male underwent a routine medical check-up. Gastroscopic examination revealed an early cancer surrounded by a slight elevation on the lesser curvature of the cardia. In order to determine the line of invasion of cancer cells and to confirm a diagnosis of the surrounding elevation, we performed endoscopic ultrasonography, which showed that the cancer cells were within the mucosa and the surrounding elevation was a lipoma, 15×7mm in size, in the submucosal layer. The cancer lesion was removed by endoscopic mucosal resection. Histological examination of the resected tissue confirmed the findings of ultrasonography.
