Diffuse large B-cell lymphoma with massive portal vein tumor thrombosis in a patient with alcoholic cirrhosis: a case report and literature review.

ABSTRACT

We describe a case of diffuse large B-cell lymphoma with massive portal vein tumor thrombosis in a patient with alcoholic cirrhosis. The tumor was detected only in the intrahepatic portal vein and the spermatic cord by FDG-PET/CT. Percutaneous liver biopsy and orchiectomy were performed and histological examination revealed diffuse large B-cell lymphoma. The tumor showed complete response after six courses of the combination chemotherapy. Portal vein tumor thrombosis of malignant lymphoma is extremely rare; moreover, it is possible that this is the first case of malignant lymphoma originating from the spermatic cord producing portal vein tumor thrombosis.
