Abstract
-
We report a case of colonic type-papillary adenocarcinoma of appendiceal origin in a 73-year-old male patient. The patient presented with right lower quadrant mass and was operated for a preoperative diagnosis of inflammatory small bowel mass. The mid one-third of the appendix showed a 3.5x3.3 cm sized, broad-based, intraluminal papillary mass. Microscopically, it was a well differentiated papillary adenocarcinoma and revealed a strong immunoreactivity to carcinoembryonic antigen. Tumor desmoplasia and acute inflammatory change were prominent.
