[Two Cases of Primary Hepatic Mucosa-Associated Lymphoid Tissue(MALT) Lymphoma].

Case 1: A 57-year-old woman with chronic hepatitis related to the hepatitis B virus was found to have a liver tumor on ultrasonography(US). Computed tomography(CT), magnetic resonance imaging(MRI), and angiography revealed 2 tumors in the liver. The patient underwent right anterior sectorectomy, and histopathologic analysis revealed mucosa-associated lymphoid tissue(MALT)lymphoma. Thirty months later, recurrence was confirmed using liver biopsy. CR was confirmed after radiation and chemotherapy, and the patient has survived. Case 2: A 71-year-old woman came to our hospital for rheumatism treatment. US, CT, and MRI revealed a tumor in the left lateral segment of the liver. The patient underwent laparoscopic partial liver resection and histopathologic analysis revealed MALT lymphoma. The patient has survived.
