Gallbladder carcinomas (GBCs) are the most common carcinomas of the biliary tract. The clear cell variant is encountered rarely, accounting for approximately 1% of all GBCs.Due to its rarity, the exact incidence and pathogenesis of this variant are unknown. Though hyalinising cholecystitis (porcelain gallbladder) is an established risk factor for development of conventional adenocarcinomas of the gallbladder, its role in the pathogenesis of the rare variants of GBC is not well-established. The current case raises the possibility that clear cell carcinoma of the gallbladder may arise through the same pathways as conventional adenocarcinomas of the gallbladder.
