title: [A case of primary hepato-biliary malignant lymphoma effectively treated with R-CHOP chemotherapy].
abstract: A 65-year-old man was admitted to our hospital because of obstructive jaundice caused by a mass extending in the porta hepatis, neck of gall bladder and extrahepatic bile duct. The specimens obtained with ultrasound-guided needle biopsy showed malignant lymphoma (diffuse large B-cell lymphoma: DLBCL). CHOP with Rituximab therapy (R-CHOP therapy) was performed. The treatment resulted in remarkable reduction of the tumor size and improvement of the biliary stenosis. We should take into consideration malignant lymphoma when we see a patient with a tumor of the hepato-biliary system.
