1974年Appelman等报告7例结肠袋形正常的多发性长条状息肉样病变命名为丝状息肉病(Filiform polyposis),认为是溃疡性结肠炎的一种非寻常后果。1975年Spark又报告一相似的病例,但继发于回肠的Crohn’s病。1978年Zegel又报告4例,也认为这些丝伏息肉是弥漫性粘膜炎的非特异性反应的后果,强调不应与肿瘤性息肉相混淆。此外,1977年Joffe收集文献上记载的个案并加上4例,报告了12例与丝状息肉病相似但丛集形成腔内肿块的病例,命名为局限性巨大假息肉病(Localized giant pseudopolyposis),强调应与乳头状腺瘤或癌鉴别。
In 1974, Appelman et al. reported that 7 cases of polycystic polypoid lesions with normal colon pouches were named filiform polyposis and considered to be an unusual consequence of ulcerative colitis. In 1975, Spark reported a similar case, but secondary to Crohn’s disease of the ileum. Zegel reported another 4 cases in 1978. It is also believed that these silky polyps are a consequence of non-specific reactions of diffuse mucositis and emphasize that they should not be confused with neoplastic polyps. In addition, in 1977, Joffe collected the documented cases and added 4 cases, and reported 12 cases of fibroid polyposis but clustered formation of intraluminal mass, named as Localized giant pseudopolyposis. Stress should be differentiated from papillary adenomas or carcinomas.
