Squamous cell carcinoma of gall bladder: A rare case

A 55-year-old female patient presented with pain in upper-right abdomen region since 2 months, associated with vomiting and fever. USG abdomen revealed well-distended gall bladder with multiple small calculi along with large hyperechoic area sludge. A provisional diagnosis of Empyema of gall bladder with cholelithiasis was considered. Laparoscopic cholecystectomy was done. The histopathological findings were suggestive of infiltrating well-differentiated keratinizing squamous cell carcinoma of the gall bladder. Subsequently, diagnosis was confirmed by means of IHC studies
