大肠幼年型息肉是一种发生结肠,尤其是直肠的较常见的息肉。特别多见于青少年,是该年龄组中最常见的肠道息肉病变。[1]儿童发病率约0.04—4％,尸检为1％。[2]其特征是腺管增生扩胀以及间质明显的炎性浸润。从Hammer1929年首次报告[3]以来,对它的性质、来源及能否癌变等,一直争论不休。为此我们收集了80年以来临安、常山二个县共28例幼年型息肉、结合有关文献,进行讨论。一、材料和方法陈二例标本为粪便内脱出物外,其余均为手术摘除或肠段切除标本,所有标本均经10％福马林固定、石蜡切片及H、E染色。
Juvenile juvenile polyps are a more common polyp that develops in the colon, especially the rectum. Particularly common in adolescents, it is the most common intestinal polyposis in this age group. [1] The incidence of children is about 0.04-4%, autopsy is 1%. [2] It is characterized by enlargement of glandular hyperplasia and marked inflammatory infiltration of interstitium. Since Hammer first reported [3] in 1929, he has been arguing over its nature, its source, and its ability to become cancerous. To this end, we have collected 28 cases of juvenile polyps from two counties in Lin’an and Changshan since the last 80 years and have combined relevant literature for discussion. First, materials and methods Chen two cases of specimens within the fecal excrement, the rest are surgical removal or bowel resection specimens, all specimens were fixed by 10% formalin, paraffin sections and H, E staining.
