Hepatic mucosa-associated lymphoid tissue lymphoma and hepatocellular carcinoma in a patient with hepatitis B virus infection.

Primary hepatic mucosa-associated lymphoid tissue (MALT) lymphoma is an extremely rare disease. A 65-year-old female patient with chronic hepatitis B presented with multiple solid masses in segment (S) 4, S5, and S6 of the liver. The nodule in S5 was diagnosed preoperatively as hepatocellular carcinoma by computed tomography, magnetic resonance imaging, and angiography.
