A pseudoepidermoid cyst arising from exuberant squamous metaplasia of the gallbladder

Arch Pathol Lab Med. 2005 Jun;129(6):e138-40. doi: 10.5858/2005-129-e138-APCAFE.

Abstract

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.
