title: [A case of ascending colon neuroendocrine carcinoma drained through a fistula of the descending part of the duodenum].
abstract: A 70-year-old woman was admitted for investigation of an abdominal tumor. Abdominal CT revealed an ascending colonic mass measuring 10 × 10 cm, with evidence of liver and lung metastasis. Colonoscopy revealed a cancerous lesion with a central ulcer in the ascending colon. Upper gastrointestinal endoscopy revealed an ulcerative lesion in the descending part of the duodenum. Histologically, the tumor showed features of neuroendocrine carcinoma. The patient died of the primary cancer two and a half months after admission. Autopsy revealed a fistula connecting the ascending colonic mass with the ulcerative lesion in the duodenum.
