Oral pulse granuloma and oral pulse granuloma associated with odontogenic keratocyst: Two clinical cases and a review of the literature

Hyaline ring granuloma of the mouth—A foreign‐body reaction that dentists should be aware of

“…All lesions diagnosed as HRG in the literature presented, under their microscopy, a foreign‐body granulomatous reaction (with multinucleated giant cells and macrophages), associated with eosinophilic material (Hase et al, 1976; Ide et al, 1982; Martín‐Hernán et al, 2019; Padmanabhan, Aparna, Karthikeyani, Dinakar, & Manickaraj, 2013; Simon et al, 1982), hyaline material (Almeida et al, 2016; Boffano, Gallesio, Campisi, Roccia, & Berrone, 2013; Chou et al, 1990; Ciola et al, 1983; Desai, 2015; El‐Labban & Kramer, 1981; Harrison & Martin, 1986; Lamear et al, 1994; McMillan et al, 1981; Pola, De La Cruz, Bustillo, Gallas, & Lestón, 2003; Sowmya, Patil, & Rao, 2014; Talacko & Radden, 1988a; Virkkunen et al, 2017), or both (Acharya et al, 2015; Brown & Theaker, 1987; Datar, Patil, Mahajan, & Dahivelkar, 2017; Dunlap & Barker, 1977; Gannepalli et al, 2016; Grover, Koshy, Sharma, & Koshy, 2015; Gueiros et al, 2008; Henriques et al, 2013; Keirby & Soames, 1985; Keskin, Duran, Alkan, & Günhan, 2000; Kotrashetti et al, 2011; Lima et al, 2015; Manjunatha et al, 2008; Neves‐Silva et al, 2017; Patil et al, 2017; Philipsen & Reichart, 2010; Santos et al, 2017; Simon et al, 1982; Williams & Bullock, 2015).…”

“…The hyaline material is not always present in the form of rings (Acharya et al, 2015; Almeida et al, 2016; Boffano et al, 2013; Chen et al, 1981; Chou et al, 1990; Ciola et al, 1983; Datar et al, 2017; Desai, 2015; Dunlap & Barker, 1977; El‐Labban & Kramer, 1981; Gannepalli et al, 2016; Grover et al, 2015; Gueiros et al, 2008; Harrison & Martin, 1986; Keirby & Soames, 1985; Keskin et al, 2000; Lamear et al, 1994; Lima et al, 2015; McMillan et al, 1981; Neves‐Silva et al, 2017; Patil et al, 2017; Philipsen & Reichart, 2010; Pola et al, 2003; Sowmya et al, 2014; Talacko & Radden, 1988a; Virkkunen et al, 2017; Williams & Bullock, 2015). They may also be ovoid, horseshoe, filamentous, or amorphous masses (Boffano et al, 2013; Brown & Theaker, 1987; Chen et al, 1981; Chou et al, 1990; Fernandez‐Flores & Saeb‐Lima, 2014; Keirby & Soames, 1985; Kotrashetti et al, 2011; Manjunatha et al, 2008; Martín‐Hernán et al, 2019; McMillan et al, 1981; Padmanabhan et al, 2013; Ponce, Lima, Rodrigues, Souza, & Lara, 2014; Rannie, 1975; Santos et al, 2017; Sato, Miyate, Fukuta, & Satoh, 2005; Scivetti et al, 2009; Talacko & Radden, 1988a; Virkkunen et al, 2017; Yang & Barnett, 1985).…”

“…It has been found in several areas, such as skin, lung, uterine tubes, gall bladder, and mouth (Gueiros et al, 2008; Knoblich, 1969; Kumar, Narasimha, Prasad, & Deo, 2011; Rhee & Wu, 2006). In the maxillomandibular complex, it may appear in microscopic pictures compatible with inflammatory and developmental odontogenic cysts, as well as in odontogenic tumors (Almeida et al, 2016; Chen, Fantasia, & Miller, 1981; Gueiros et al, 2008; Henriques et al, 2013; Ide, Kusama, Saito, & Umemura, 1982; Manjunatha, Kumar, & Raghunath, 2008; Marcussen, Peters, Carmel, Mickleborought, & Robinson, 1993; Martín‐Hernán et al, 2019; Talacko & Radden, 1988a, 1988b). Initially, it was considered only as a complementary histological finding, but today it is also recognized as a distinct clinical entity.…”
