Primary mucinous adenocarcinoma of the appendix is a rare gastrointestinal malignancy. Fistulous tract formation is a complication that is cited in literature. An 85-year-old man with multiple comorbidities presented with several weeks of persistent non-bloody diarrhea. Laboratory work-up was non-diagnostic. Abdominal imaging with barium contrast showed an enterocolonic fistulous tract extending from the duodenum to the cecum involving an enlarged appendiceal mass. Subsequent biopsy confirmed mucinous appendiceal neoplasm with peritoneal spread to the liver and mesentery. This is the first report describing an enterocolonic fistula formation resulting from this malignancy.
阑尾原发性黏液腺癌是一种罕见的胃肠道恶性肿瘤。文献中提到瘘管形成是一种并发症。一名患有多种合并症的85岁男性出现了数周持续性非血性腹泻。实验室检查未明确诊断。腹部钡剂造影显示一个从十二指肠延伸至盲肠的肠结肠瘘管，涉及一个增大的阑尾肿块。随后的活检证实为黏液性阑尾肿瘤并伴有腹膜扩散至肝脏和肠系膜。这是描述由这种恶性肿瘤导致肠结肠瘘管形成的首例报告。
