Squamous lesions of the gallbladder are uncommon. We report a case of a pseudoepidermoid cyst in a middle-aged woman arising on a background of chronic cholecystitis and cholelithiasis, which induced exuberant squamous metaplasia of the entire gallbladder mucosa, clinically mimicking a gallbladder tumor. To our knowledge, this is the first such reported case in the English literature.
