title: Large intestinal type-urachal adenocarcinoma with focal expression of prostatic specific antigen.
abstract: We present a case of colonic-type adenocarcinoma, which might arise from an urachal remnant through a villous adenoma. The cancer tissue in the present case showed focal immunoreaction to prostate-specific antigen (PSA). This is the first report of urachal adenocarcinoma expressing PSA.
