A 70-year-old woman was admitted to our hospital because of an abdominal tumor. The tumor was found to be a transverse colon cancer by colonic examinations. Preoperative ultrasonography revealed a gallstone and irregular mucosal lesions of the gallbladder. Right hemicolectomy and cholecystectomy were carried out. The resected gallbladder showed a mixed stone and granular, partly nodular mucosal elevated lesions in almost the entire gallbladder. Histologically, the elevated mucosal lesions were found to be composed of metaplastic pseudopyloric glands, some of which were dilated and causing mucosal thickening, and goblet cells and some panethoid cells were seen in the metaplastic glands. Although metaplastic cholecystitis which is detected by medical imagings is very rare, it should be kept in mind in differential diagnosis of elevated mucosal lesions of the gallbladder as an entity mimicking type IIa early cancer.

Key words
metaplastic cholecystitis, superficially elevated early cancer of the gallbladder
