  • Look Inside

 A 56-year-old man admitted to our hospital with chief complaints of bloody stool and lower abdominal pain. Barium enema examination disclosed a small, oval and irregularly-shaped flat but elevated lesion in the transverse colon. Frontal view of barium enema study showed a small barium spot in its center, and lateral view disclosed an arch-shaped deformity. Colonoscopic examination showed a erythematous flat but elevated lesion with a small and shallow central depression. The resected specimen contained a reddish and round-shaped flat but elevated lesion with a shallow central depression, 7×7 mm in size. Histological examination disclosed well differentiated tubular adenocarcinoma. Cancer cells invaded scatteringly into the propria muscularis accompanied by fibrosis in the submucosal layer. There was marked focal hypertrophy of the propria muscularis. No metastatic lesion was detected in the resected lymph nodes.
