We report a case of probable contact-allergic gastritis in a 46-year-old woman. Clinical examination revealed lichenoid mucosal lesions of the gums adjacent to bridges and crowns that had been implanted several weeks back. Since implantation, the patient had suffered from gastrointestinal complaints (including stomach pain). Gastroscopy showed eosinophilic gastritis. Patch testing done under the diagnosis of contact allergic stomatitis showed positive reactions to: gold sodium thiosulphate; manganese (II) chloride; nickel (II) sulphate; palladium chloride; vanadium (III) chloride and zirconium (IV) chloride. The crowns and bridge contained gold, palladium and zirconium chloride, hence they were replaced by titan-based dentition. Shortly after replacing the artificial dentition, all gastrointestinal symptoms resolved spontaneously without further treatment. Delayed-type allergy against the components of artificial dentition seemed to be the cause of gastritis.<\/jats:p>","DOI":"10.1136\/bcr-2012-006916","type":"journal-article","created":{"date-parts":[[2012,11,28]],"date-time":"2012-11-28T05:53:14Z","timestamp":1354081994000},"page":"bcr2012006916","source":"Crossref","is-referenced-by-count":5,"title":["Contact allergic gastritis: an underdiagnosed entity?"],"prefix":"10.1136","volume":"2012","author":[{"given":"Claudia","family":"Pf\u00f6hler","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"K\u00f6rner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Vogt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cornelia S L","family":"M\u00fcller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2012,11,28]]},"reference":[{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02239356"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.2","doi-asserted-by":"crossref","first-page":"484","DOI":"10.4049\/jimmunol.97.4.484","article-title":"Delayed-type contactant hypersensitivity elicited in epithelia of vagina, uterus and colon of the guinea pig","volume":"97","author":"Macher","year":"1966","journal-title":"J Immunol"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.3","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.1964.01590250105018"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.4","first-page":"57","article-title":"Induction of an allergic gastritis in guinea pigs sensitized to 2, 4-dinitrochlorobenzene\u2014experimental studies on gastritis from the viewpoint of contact allergy","volume":"22","author":"Nakajima","year":"1976","journal-title":"Osaka City Med J"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.5","first-page":"109","article-title":"The induction of an allergic gastritis of delayed-type in guinea pigs sensitized to potassium bichromate\u2014further studies on the gastritis related to contact allergy","volume":"23","author":"Nakajima","year":"1977","journal-title":"Osaka City Med J"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.6","doi-asserted-by":"publisher","DOI":"10.1097\/00005176-199607000-00012"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.7","doi-asserted-by":"publisher","DOI":"10.1016\/j.bpg.2007.11.010"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.8","doi-asserted-by":"publisher","DOI":"10.1097\/PAP.0b013e318229bfe2"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaci.2003.10.047"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.10","doi-asserted-by":"publisher","DOI":"10.3109\/00365521.2011.579998"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.11","doi-asserted-by":"publisher","DOI":"10.1186\/1824-7288-37-18"},{"key":"2025042707414930000_2012.nov27_1.bcr2012006916.12","doi-asserted-by":"publisher","DOI":"10.1016\/S1085-5629(97)80022-3"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2012-006916","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T10:41:58Z","timestamp":1745750518000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2012-006916"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,11,28]]},"references-count":12,"alternative-id":["10.1136\/bcr-2012-006916"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2012-006916","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,11,28]]}}}
