[Morphological characteristics of inflammatory polyps of the large intestine in children].

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.
