We have experienced a case of hinf3 huge mucinous cancer of the gallbladder infiltrating into the greater omentum. This paper presents the case, together with a review of 16 domestic cases including ours. A 61-year-old woman was admitted to the hospital because of epigastric pain. Gallbladder cancer infiltrating into the left medial segment of the liver was diagnosed preoperatively, and an embolization of the right portal branch was performed, followed by an extended right lobectomy of the liver, an excision of the extrahepatic bile duct, and lymph nodes dissection. The tumor was the swollen gallbladder 13cm in diameter, with necrosed tissues and large volumes of mucus in the lumen. Pathologic diagnosis was well differentiated mucinous cancer of the gallbladder with invasion into the greater omentum and findings of hinf3, revealing stage IVa. Mucinous cancer is a cancer in which mucous lake and mucous nodules are formed outside the cancer cells. It is subclassified into well differentiated type deriving from papillary adenocarcinoma, well and moderately differentiated tubular adenocarcinoma, and poorly differentiated type deriving from signet ring cell carcinoma. In a review of the domestic 16 cases, there are more cases of relatively early cancer, and even cases of poorly differentiated type that is thought to have a poor prognosis had a favorable prognosis after resection of the foci. We have difficulty in making the definite diagnosis for the disease, but favorable prognosis can be expected by appropriated selection of operative procedure according to the progress of the cancer and active resection.
