Objectives: Primary hepatic lymphoma is an uncommon cause of hepatic space-occupying lesions. Methods: We describe the case of a 73-year-old man with primary hepatic lymphoma, who presented with a low-grade fever and lower limb weakness which had progressed in the past 2 months. Results: Abdominal ultrasound and computed tomography showed multiple small hepatic tumors. Echo-guided biopsy of the hepatic tumor demonstrated primary hepatic diffuse large B cell lymphoma. Moreover, bone marrow was uninvolved, but the bone marrow smear disclosed hemophagocytosis, which is uncommon in diffuse large B cell lymphoma. Chemotherapy with bendamustine and rituximab treatment was initiated with a dramatic response: hepatic tumors markedly shrank in size shown by follow-up computed tomography and the patient returned to his normal life. Nevertheless, the response was sustained for only 8 months. Finally, the disease resisted further chemotherapy and this patient died of a severe Klebsiella pneumoniae infection. Conclusion: Chemotherapy with bendamustine and rituximab has shown a dramatic, but not durable, response in the present case with old age and multiple comorbidities.
