幼年型息肉为儿童期较常见的一种息肉,但亦可发生在成年人。病理上以腺体扩张伴囊肿形成及丰富的纤维性间质为主要特征。长期以来对此型息肉的性质与来源、恶变与否等争论颇大,为了进一步搞清这些问题,特进行本研究。 Juvenile polyps are a common type of polyp in childhood but may also occur in adults. Pathologically, it is characterized by glandular expansion with cyst formation and abundant fibrous interstitium. There has been considerable debate over the nature and origin of this type of polyp, and whether it has been malignant or not. In order to further clarify these issues, this study was conducted.
