An unusual case of hyaline ring granuloma arising from the connective tissue wall of a residual apical periodontal cyst is reported. Hyaline rings with foreign-body type giant cell inclusions were a significant feature in the histopathologic diagnosis. Histochemical and polarized light microscopic studies suggested that the introduction of foreign material, possibly cellulose, through the postextraction socket into the cystic wall may have caused the granulomatous reaction and formation of the hyaline ring granuloma. The clinical features of this case and 66 previously reported cases, as well as the pathogenesis of the hyaline rings, are discussed.
报告了一例罕见的透明环肉芽肿病例，其起源于残余根尖牙周囊肿的结缔组织壁。伴有异物型巨细胞包涵体的透明环是组织病理学诊断的一个显著特征。组织化学和偏光显微镜研究表明，拔牙窝内的异物（可能是纤维素）进入囊壁，可能引发了肉芽肿反应并形成了透明环肉芽肿。本文讨论了该病例以及66例既往报道病例的临床特征，以及透明环的发病机制。
