Hyaline ring granuloma is a rare oral lesion with an unclear and controversial etiology, characterized by the presence of rings of palely eosinophilic structureless material (the so-called hyaline rings) with multinucleated giant cells around and within the very same rings.Various theories have been proposed about the pathogenesis of hyaline ring granulomas. Many authors consider a vegetable origin, suggesting that it may represent a reaction to foreign material such as food (and in particular pulses). Instead, other authors deny this possibility, proposing that the hyaline rings might represent degenerated blood vessels, degenerated collagen, or fibrosed extravasated serum proteins.The aim of this article is to present a case of hyaline ring granuloma and to briefly review the literature.
透明环肉芽肿是一种罕见的口腔病变，其病因尚不明确且存在争议，其特征是存在淡嗜酸性无结构物质的环（所谓的透明环），在这些环的周围和内部有多核巨细胞。关于透明环肉芽肿的发病机制已经提出了各种理论。许多作者认为其起源于植物，表明它可能是对诸如食物（特别是豆类）等异物的反应。相反，其他作者否认这种可能性，提出透明环可能代表退化的血管、退化的胶原蛋白或纤维化的外渗血清蛋白。本文的目的是介绍一例透明环肉芽肿病例并简要回顾相关文献。
