Results We report a case of an unexpected lesion found in the gallbladder of a 42-year-old woman. She was recently diagnosed with a breast carcinoma. Ultrasonography of the liver, performed as a staging investigation, showed a 2.3 cm sessile polypoid mass in the galbladder. An additional CT scan confirmed this finding and showed no other lesions. Radiologically the lesion was suspect for gallbladder carcinoma. Transserosal growth could not be excluded. A laparoscopic cholecystectomy with local lymph node resection was performed. Macroscopically we found a soft, red, raised 3 cm large mass in the body of the gallbladder. Histological examination showed fundic-type gastric mucosa with several cystic spaces corresponding to dilated foveolae. A few foci of heterotopic pancreatic tissue were also present. There was no intestinal metaplasia nor dysplasia. The surrounding mucosa of the gallbladder showed extensive cholesterolosis, but no cholecystitis or signs of cholelithiasis.
