We reported a case of malignant lymphoma appearing from porta hepatical lymph nodes in chronic hepatitis C. A 44-year-old man was diagnosed as choronic hepatitis C by liver biopsy in 1993. He was treated with the six million units of Interferonα-2a for six months, but there was no response. We followed up with abdominal ultrasonography, and detected a 35mm low-echoic mass. We recommended an operation, but he refused. The mass had grown to 78mm on December 2004, we biopsied it with ultrasonograpy assist. The mass was diagnosed as diffuse large B cell lymphoma. We started CHOP plus rituximab chemotherapy and the mass had shrunken. A chronic hepatitis C patient have a high incidence of porta hepatical lymph nodes swelling, so we need to be careful about appearance of malignant lymphoma from porta hepatical lymph nodes, if the lympho node size increased.
