title: [A case of transverse colon cancer mimicking urachal cancer].
abstract: A 55-year-old man was admitted to our hospital because of abdominal distension. Computed tomography revealed an abscess in the anterior abdominal wall and invasion of the large intestine. Biopsy of the large intestine revealed adenocarcinoma. Immunohistochemically, the antigen expression profile of the tumor was positive for cytokeratin 7, cytokeratin 903 (34βE12), and cytokeratin 20. We diagnosed the tumor as urachal cancer and performed surgery. Examination of the resected specimen showed that the tumor was located in the transverse colon. Finally, the patient was diagnosed as having transverse colon cancer with urachal abscess.
