title: Early carcinoma of the gallbladder, noninvasive carcinoma originating in the Rokitansky-Aschoff sinus: a case report.
abstract: A patient was reported who underwent cholecystectomy under the diagnosis of chronic cholecystitis with calculi and adenomyomatosis, but it proved to be an early carcinoma of the gallbladder originating in and limited to the Rokitansky-Aschoff sinus (cyst-like structure). Early carcinoma of the gallbladder in this category is rare and this case report may be the first one in the literature.
