A case of heterotopic gastric mucosa (pyloric gland) in the wall of the gallbladder was reported. A 58 year-old woman was admitted with a history of sudden attack of hypochondralgia radiating to the back, but she had no fever and jaundice. Ultrasonography demonstrated high echo at the neck and body of the gallbladder. Cholecystectomy was performed with a diagnosis of the gallbladder tumor containing gall stone. The surgical specimen revealed a 15 X 14 X 8mm subserosal tumor in the body and chronic cholecystitis, but showed no metaplastic differentiation in the mucosa. The cause was considered to be congenital. Heterotopic tissue in the wall of the gallbladder was very rare. In the literature, there were 29 cases of gastric mucosa and 27 cases of pancreatic tissue. The mean age of incidence were 31.9 and 42.0 year-old, respectively. There is no sex difference. The lesion was located in the cystic duct and the neck of the gallbladder in half the patients. Cholelithiasis and/or cholecystitis was complicated in many cases, and it might be associated with heterotopic tissue whereas the etiology is unknown.
报告了一例胆囊壁内异位胃黏膜（幽门腺）病例。一名58岁女性因突发季肋部疼痛并向后背部放射入院，但无发热及黄疸症状。超声检查显示胆囊颈部和体部有高回声。诊断为胆囊肿瘤伴胆结石，遂行胆囊切除术。手术标本显示胆囊体部有一个15×14×8mm的浆膜下肿瘤及慢性胆囊炎，但黏膜未见化生分化。病因考虑为先天性。胆囊壁内的异位组织非常罕见。文献中，有29例胃黏膜异位和27例胰腺组织异位。平均发病年龄分别为31.9岁和42.0岁。无性别差异。半数患者病变位于胆囊管和胆囊颈部。许多病例合并胆石症和/或胆囊炎，可能与异位组织有关，但其病因尚不清楚。
