In this report, we describe a case of gastroesophageal submucosal hematoma that developed due to vomiting in a patient with no history of bleeding and resolved with conservative treatment. A 69\u2010year\u2010old man presented with precordial pain and hematemesis after vomiting. A diagnosis of idiopathic gastroesophageal submucosal hematoma was made by computed tomography scan, magnetic resonance imaging, and esophagogastroduodenoscopy. Healing was achieved by conservative treatment with fasting, rehydration, and acid suppression. When a patient presents with sudden chest pain, hematemesis, and dysphagia, the possibility of this disease should be considered.<\/jats:p>","DOI":"10.1002\/deo2.284","type":"journal-article","created":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T02:45:36Z","timestamp":1692672336000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["A case of idiopathic gastroesophageal submucosal hematoma in a patient with no predisposition to bleeding"],"prefix":"10.1002","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8850-8252","authenticated-orcid":false,"given":"Takaaki","family":"Iwado","sequence":"first","affiliation":[{"name":"Department of Gastroenterology and Hepatology Kurashiki Central Hospital  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6742-0208","authenticated-orcid":false,"given":"Hirokazu","family":"Honda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology Kurashiki Central Hospital  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuhiro","family":"Gotoda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology Kurashiki Central Hospital  Okayama Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,8,21]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.7888\/juoeh.36.123"},{"key":"e_1_2_5_3_1","first-page":"1403","article-title":"A case of gastric submucosal hematoma with al amyloidosis","volume":"52","author":"Murawaki Y","year":"2010","journal-title":"Gastroenterol Endosc"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00042737-200012100-00014"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.314105177"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.1999.01314.x"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-6757(97)90027-9"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v9.i20.5683"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2003.356"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0730-725X(95)00047-K"}],"container-title":["DEN Open"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.284","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,13]],"date-time":"2025-08-13T06:48:54Z","timestamp":1755067734000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/deo2.284"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,8,21]]},"references-count":9,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2024,4]]}},"alternative-id":["10.1002\/deo2.284"],"URL":"https:\/\/doi.org\/10.1002\/deo2.284","archive":["Portico"],"relation":{},"ISSN":["2692-4609","2692-4609"],"issn-type":[{"value":"2692-4609","type":"print"},{"value":"2692-4609","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,8,21]]},"assertion":[{"value":"2023-02-14","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-08-07","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-08-21","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e284"}}
