“…Gastric heterotopia in the gall bladder may be asymptomatic or in the form of pain in the right hypochondrium radiating to the right shoulder, as in our patient's case [11]. Previously, findings regarding serological parameters have been rarely described in the literature [12].…”

Heterotopia is defined as an ectopic localization of normal tissue; the heterotopia of the gastric mucosa can be observed all along the digestive tract. The localization in the gallbladder is exceptional. The diagnosis is histological, it may present some complications including ulceration and the risk of malignancy. We report the case of heterotopia of the gastric mucosa in the gallbladder while presenting the clinical, radiological and therapeutic features of this exceptional lesion.

Background:Heterotopic gastric tissue can be found in the entire gastrointestinal tract. It is usually located in the upper intestine. Rarely, it can be found in the gallbladder. This study describes several clinically, imaging features as well as histopathology findings of heterotopic gastric tissue in gallbladder (HGM).Methods:The radiologic database of 1 tertiary university hospital was retrospectively screened for HGM. Additionally, a systemic review of the Medline database was conducted to identify previously published cases reports. In all cases clinical, imaging as well as histopathology features were retrieved from the papers.Results:In our databases, 1 patient with HGM was identified. Additionally, the systemic review yielded 32 suitable papers with 34 patients. Clinically, most of the patients suffered from abdominal discomfort. Most of the lesions were located in the lower gallbladder, especially (n = 14, 40%) in the gallbladder neck. On sonography, in 20.7% a broad-based mass was described. In 10.3% a sessile polyp was identified. In 5 cases, the mass was characterized as hyperechoic (55.5%), as isoechoic in 3 (33.3%) cases, and hypoechoic in 1 (11.1%). On computed tomography (CT), the lesions were most frequently hyperdense and all of them showed a slightly enhancement after application of contrast medium. On histopathology, most cases revealed heterotopic gastric mucosa of body-fundic type (60%) with chief and parietal cells, followed by pyloric type glands (20%). Every patient was treated with cholecystectomy and all had an uneventful recovery.Conclusion:HGM is a rare disorder with several differential diagnoses. Typically features were described to identify HGM in clinical routine and rule out malignant diseases like gallbladder carcinoma.

“…Since the first description by Ewell and Jackson in 1939, GH has been described throughout the GI tract, pancreatobiliary tract, nasopharynx and several unusual locations, such as the mediastinum and scrotum . Although the exact pathogenesis remains largely unresolved, several hypotheses have been put forward to explain the occurrence of heterotopic gastric mucosa in the GI tract.…”
