A Case of Primary Hepatic B-cell Lymphoma of Mucosa-associated Lymphoid Tissue (MALT)-Type

ABSTRACT

Mucosa-associated lymphoid tissue (MALT) lymphoma is a low grade B cell lymphoma that, occurs in numerous sites including the stomach, ocular adnexa, thyroid, lung and breast; however, primary hepatic lymphoma is extremely rare. Only about 20 cases have been reported world wide. We recently experienced a case of primary hepatic B-cell lymphoma of the MALT type in a 63-year old female patient. She presented with abdominal pain. The CT, ultrasonogram and PET-CT showed a hepatic nodular mass. A biopsy specimen of the liver revealed MALT lymphoma. There was no evidence of the lymphoma in the extrahepatic lesion. She received segmentectomy of liver and was then treated with CVP (cyclophosphamide, vincristine and prednisolone) chemotherapy. She has been followed up for 6 months since the therapy, and she remains asymptomatic.
