A CASE REPORT OF EARLY COLON CACNER SHOWING SUPERFICIALLY WIDESPREADED NODULAR TUMOR AROUND APPENDICEAL ORIFICE

Abstract

Our case is a 73 year-old man. Barium enema and colonoscopy showed a nodular tumor like ha around the appendiceal orifice. Histologically, biopy specimens revealed a tubular adenoma with severe atypia. Ileocecal resection was done. Macroscopically, the lesion was a well demarcated f alt tumor 35×60mm in size with nodular-aggregated surface around the appendiceal orifice. Histological examination revealed carcinoma in adenoma. In microangiography, the stalk vessels was noted in the nodular area, and the vascular patterns in the flat elevated lesion were similar to the mucosal vessels. This is a rare case in the location of the tumor, and the multiple hyperplastic polyps in the stomach were associated.
