Colonic neoplasia can arise from normal mucosa near or within a diverticulum. However, an adenocarcinoma arising within a diverticulum is a very rare phenomenon and to date only sporadic cases have been reported (1-8). Due to the lack of muscular layers within the diverticu- lum, the use of endoscopic polypectomy of a tumour within the diverticulum carries a risk of colonic perfora- tion. Additionally, it is usually difficult to determine whether the tumour component is benign or malignant ; hence, special precautions should be implemented in the diagnosis and treatment of such patients. A 71-year-old man was admitted to Nishijin Hospital because of mele- na on November 5, 2009. |
