Obstruction of the biliary tree by large amounts of mucinous substance was reported in two patients with mucin-producing cholangiocarcinoma. The tumor graw intralumenally and they were histologically papillary adenocarcinoma showing excessive mucin production. No metastasis was found in both cases. Although mucin-producing cholangiocarcinoma is ocassionally associated with clonorchiasis, no evidence was noted that two cases had a history of clonorchis infection. Mucinous obstruction of the biliary tree is extremely rare, however, in cases representing peculiarly shaped abnormal defects of the bile duct by cholangiography, mucinous obstruction should be remainded despite of its rarity.
