Summary:A 53-year-old male visited our hospital for further examination because of positive fecal occult blood. Radiological and endoscopic examinations revealed a submucosal lesion of the rectum. It was considered to be possibly a submucosal tumor, but diagnosis of this lesion by means of endoscopic biopsy was suspected adenocarcinoma. Low anterior resection was performed. The lesion, 1.4 cm in the largest diameter, looked like a submucosal tumor marcroscopically. Pathological examination revealed well differentiated adenocarcinoma with lymphoid stroma and invasion to the submucosal layer. Reports of colorectal cancer with submucosal tumor-like morphology and lymphoid stroma are rare. This was a rare case, and the developement and progression of such tumors were discussed.
