Here, we report a 31-year-old male patient with GH in ileum presented with bowel perforation and mass formation in the mesentery mimicking perforated small bowel tumor. Microscopic examination of the lesion showed completely differentiated gastric body-type mucosa with mucosal ulceration, fistula formation and bowel perforation. This case raises the awareness that GH may cause severe complications and should be included in the differential diagnosis for acute abdominal pain especially in patients with a mass lesion at an unusual location.<\/jats:p>","DOI":"10.1093\/jscr\/rjaa224","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T19:09:45Z","timestamp":1591729785000},"source":"Crossref","is-referenced-by-count":0,"title":["Gastric heterotopia with perforation mimicking neoplastic process in ileum"],"prefix":"10.1093","volume":"2020","author":[{"given":"Quinlan","family":"Carlson","sequence":"first","affiliation":[{"name":"Department of Pathology, Banner-University Medical Center, College of Medicine, University of Arizona, Tucson AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Umamaheshwari","family":"Golconda","sequence":"additional","affiliation":[{"name":"Department of Pathology, Banner-University Medical Center, College of Medicine, University of Arizona, Tucson AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0055-2206","authenticated-orcid":false,"given":"Belinda","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Pathology, Banner-University Medical Center, College of Medicine, University of Arizona, Tucson AZ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,7,23]]},"reference":[{"key":"2020072322264248900_ref1","doi-asserted-by":"crossref","first-page":"138","DOI":"10.3109\/00365521.2013.860558","article-title":"Heterotopic gastric mucosa of the gastrointestinal tract: prevalence, histological features, and clinical characteristics","volume":"49","author":"Yu","year":"2014","journal-title":"Scand J Gastroenterol"},{"key":"2020072322264248900_ref2","doi-asserted-by":"crossref","first-page":"543","DOI":"10.1111\/j.1572-0241.2004.04082.x","article-title":"Heterotopic gastric mucosa of the esophagus: literature-review and proposal of a clinicopathologic classification","volume":"99","author":"von Rahden","year":"2004","journal-title":"Am J Gastroenterol"},{"author":"Schumidt","key":"2020072322264248900_ref3","first-page":"1805"},{"key":"2020072322264248900_ref4","doi-asserted-by":"crossref","first-page":"2061","DOI":"10.1016\/S0022-5347(01)66109-3","article-title":"Heterotopic gastric tissue in the scrotum","volume":"155","author":"Khan","year":"1996","journal-title":"J Urol"},{"key":"2020072322264248900_ref5","doi-asserted-by":"crossref","first-page":"54","DOI":"10.1007\/BF02470847","article-title":"Gastrin producing cells in the regenerating mucosa of the small intestine","volume":"18","author":"Yokoyama","year":"1988","journal-title":"Jpn J Surg"},{"key":"2020072322264248900_ref6","doi-asserted-by":"crossref","first-page":"2555","DOI":"10.1016\/j.febslet.2008.06.024","article-title":"Cdx2 initiates histodifferentiation of the midgut endoderm","volume":"23","author":"Stringer","year":"2008","journal-title":"FEBS Lett"},{"key":"2020072322264248900_ref7","article-title":"Perforation of heterotopic gastric mucosa in ileal duplication in an adult: a case report","volume":"2","author":"Paulvannan","year":"2019","journal-title":"J Surg Case Rep"},{"key":"2020072322264248900_ref8","doi-asserted-by":"crossref","first-page":"397","DOI":"10.1097\/00000478-198705000-00009","article-title":"Adenocarcinoma of the upper esophagus arising in ectopic gastric mucosa.
