Gall bladder carcinoma is the most common type of tumor of the biliary tract and adenocarcinoma is the major histopathological subtype. Mucinous variant is a rare subtype and mucinous carcinoma accompanied with signet ring is extremely rare. When mucinous component exceeds 90% of the tumor, it is labeled as pure mucinous carcinoma. Immunohistochemistry helps to distinguish primary mucinous adenocarcinoma of gall bladder from pseudo myxoma peritonei from appendiceal neoplasm. Mucinous carcinoma is CK 7 positive and CK20 negative. We report a case of mucinous adenocarcinoma arising from the fundus of the gall bladder.
