Heterotopic gastric mucosa in the gallbladder is an unusual entity and is usually clinically silent. We report a 75-year-old female patient who presented with intermittent upper abdomial pain radiating to the back. Abdominal imaging studies showed a sessile polypoid lesion and a gallstone in the gallbladder. Gallbladder carcinoma was suspected and cholecystectomy performed. Intraoperative frozen section examination suggested mucinous tumor, suspicious for malignancy. However, the permanent sections revealed aberrant gastric tissue consisted of gastric pyloric and fundic glands of heterotopic gastric mucosa with intestinal metaplasia in the gallbladder.
胆囊中的异位胃黏膜是一种罕见的情况，通常在临床上没有症状。我们报告一名75岁女性患者，她出现间歇性上腹部疼痛并放射至背部。腹部影像学检查显示胆囊内有一个广基息肉样病变和一枚胆结石。怀疑为胆囊癌并进行了胆囊切除术。术中冰冻切片检查提示为黏液性肿瘤，怀疑为恶性。然而，永久切片显示胆囊内存在由异位胃黏膜的胃幽门腺和胃底腺组成的异常胃组织，并伴有肠化生。
