Filiform polyposis (FP) of the colon is an uncommon entity that is occasionally encountered in patients with inflammatory bowel disease (IBD). FP is morphologically characterized by multiple slender worm-like projections consisting of submucosal cores lined with normal mucosa. To date, only two cases of FP have been reported in patients with inflammatory conditions of the gastrointestinal tract other than ulcerative colitis or Crohn's disease. We report an additional case of FP occurring in an 83-year-old man with no history of IBD. The patient underwent anterior resection of the sigmoid colon for perforated diverticulitis. Around the diverticular orifice, localized FP involving a 13-cm colonic segment was observed. The filiform polyps consisted of submucosal fibrovascular cores lined with normal mucosa without epithelial dysplasia. To our knowledge, this is the first reported case of FP associated with colonic diverticulitis in a patient without IBD.
结肠丝状息肉（FP）是一种不常见的疾病，偶尔在炎症性肠病（IBD）患者中发现。FP 在形态学上的特征是由多个黏膜下核心组成的多个细长虫样突起，这些核心被正常黏膜覆盖。迄今为止，除溃疡性结肠炎或克罗恩病外，仅在胃肠道炎症性疾病患者中报告了两例 FP。我们报告了一例 83 岁男性的 FP 病例，该患者无 IBD 病史。患者因穿孔性憩室炎而行乙状结肠前切除术。在憩室口周围，观察到局部涉及 13cm 结肠段的 FP。丝状息肉由黏膜下纤维血管核心组成，表面覆盖正常黏膜，无上皮异型增生。据我们所知，这是首例在无 IBD 的患者中与结肠憩室炎相关的 FP 报道。
