title: Large bronchogenic cyst of stomach: A case report.
abstract: BACKGROUND
  Bronchogenic cysts are congenital cysts arising as an abnormal budding from primitive tracheobronchial tree. They are lined by pseudostratified columnar or cuboidal ciliated epithelium and contain smooth muscle fibers, submucosal bronchial glands and/or cartilage. They are most frequently located in the mediastinum or the lung parenchyma. Intramural occurrence of bronchogenic cyst in the gastric wall is very rare.
  
  
  METHODS
  We present a case of 65-year-old lady with a 7×8cm lesion in the gastric cardia suspicious of gastrointestinal stromal tumor. Because of the large size, total gastrectomy with Roux-en-Y esophagojejunal anastomosis was performed. The postoperative course was uneventful. Histopathological examination revealed a sub-mucosal cyst lined by PCCE with presence of smooth muscle fibers and focal mucous glands. Final diagnosis of bronchogenic cyst was made. On the last follow up at one year, she was symptom free.
  
  
  CONCLUSIONS
  On extensive Medline/Pubmed search, only 38 cases of gastric bronchogenic cysts were found to be reported till date. They are typically located in the posterior gastric wall close to the gastric cardia. On radiological imaging, they appear as well defined intramural cystic lesion without any characteristic features. Surgical resection is considered in symptomatic cases or in case of diagnostic dilemma.
  
  
  CONCLUSIONS
  Gastric bronchogenic cysts often mimic gastrointestinal stromal tumor on preoperative imaging. They should be included in the differential diagnosis while dealing with an intramural gastric lesion close to the cardia or gastroesophageal junction.
