Abstract

Background: There are occasional reports of osseous metaplasia (OM) occurring in gastrointestinal polyps. We report 4 cases occurring in juvenile retention polyps. Case reports: Four juvenile retention polyps presented with rectal bleeding. Microscopically there was osseous metaplasia in addition to the typical surface ulceration and granulation tissue appearance. Discussion/conclusion: Osseous metaplasia was only detected on histopathologic examination of the resected polyps. Although the clinical significance is not established, OM suggests that the polyps have been present for a longer period of time.

幼年性息肉骨化生四例并文献复习

摘要

背景：偶尔有报道称胃肠道息肉发生骨化生（OM）。我们报告了 4 例发生在幼年性息肉中的病例。病例报告：四例幼年性息肉潴留伴有直肠出血。显微镜下除了典型的表面溃疡和肉芽组织外观外，还有骨化生。讨论/结论：仅在切除的息肉的组织病理学检查中检测到骨化生。虽然临床意义尚未确定，但 OM 表明息肉已存在较长时间。
