Hyaline ring (pulse granuloma) is a rare benign lesion of the oral cavity soft tissues characterized by round or oval structures with scalloped borders composed by a collagenous matrix variable associated with inflammatory and foreign bogy giant cells. Vegetable fragments are variably identified. Whereas most cases occur in the oral cavity, it has also been described in other sites such as the lung and rectum. It is thought by most to represent a reaction to foreign materials. We report two incidentally discovered cases of colonic hyaline rings associated with perforated diverticulitis. Vegetable residues were seen in both cases.
透明环（脉冲肉芽肿）是口腔软组织的一种罕见良性病变，其特征为圆形或椭圆形结构，边界呈扇贝状，由胶原基质组成，该基质与炎症和异物巨细胞相关，变化不定。可不同程度地识别出植物碎片。虽然大多数病例发生在口腔，但也有在其他部位如肺和直肠的报道。大多数人认为它是对外来物质的一种反应。我们报告两例偶然发现的与穿孔性憩室炎相关的结肠透明环病例。两例均可见植物残渣。
