 A 72-year-old man with the chief complaint of pollakisuria,miction pain and fecaluria was referred to our hospital. CT,MRI,cystoscopy and colonoscopy with biopsy revealed the sigmoid colon cancer and the sigmoid colovesical fistula. Under the diagnosis of bladder invasion of the sigmoid colon cancer,sigmoidectomy and partial cystectomy were performed. Histologically,the resected sigmoid colon tumor showed moderately differentiated adenocarcinoma with fistula formation to urinary bladder. The carcinoma involving the deep subserosa and the adventitia of the adhered urinary bladder were observed,however,in the fistula wall,many foreign bodies(fish bones and seeds)were embedded and marked inflammation with foreign body granulatoma formation were noticed.(Rinsho Hinyokika 61:453-455,2007)
