Inflammatory polyps of 32 children were studied morphologically. Inflammatory polyps comprised more than 20% of all removed polyps in 1983-2002. They were second among common polyps in children after juvenile polyps. Typical location of inflammatory polyps was the rectum. Characteristic morphological features of inflammatory polyps in children are predomination of the inflammatory component represented by granulation tissue. In contrast to juvenile polyps granulation tissue in inflammatory polyps does not contain glands but may contain foreign bodies and giant cells. About one third of the inflammatory polyps in children in this study was associated with mucosal prolapse syndrome evidenced by proliferation of smooth muscle cells and fibrous tissue in the stroma of polyp glandular component.
对32例儿童炎性息肉进行了形态学研究。在1983 - 2002年期间，炎性息肉占所有切除息肉的20%以上。它们是儿童常见息肉中仅次于幼年性息肉的第二大类。炎性息肉的典型部位是直肠。儿童炎性息肉的特征性形态学特征是以肉芽组织为代表的炎症成分占主导。与幼年性息肉不同，炎性息肉中的肉芽组织不含腺体，但可能含有异物和巨细胞。本研究中约三分之一的儿童炎性息肉与黏膜脱垂综合征有关，表现为息肉腺性成分间质中平滑肌细胞和纤维组织增生。
