Abstract
Primary hepatic extranodal mucosa-associated lymphoid tissue (MALT) lymphoma is seen extremely rare compromising 0,016% among non-Hodgkin lymphomas. Association of chronic inflammatory conditions or infectious processes mostly hepatitis B virus (HBV) infection has been reported by scarce number of case presentations. Whereas MALT lymphoma accompanied by echinococcus granulosus infection was described only in one primary pulmonary lymphoma case. We herein present a primary hepatic MALT lymphoma case with both HBV carrier state and liver hydatid cyst history. A 86 years old male patient referred to our clinic with a sole liver mass and was diagnosed with primary hepatic MALT lymphoma by core biopsy. Positron emission tomography detected increased uptake in the liver lesion without any other uptake site. He was successfully treated with rituximab-chemotherapy, tenofovir and albendazole. By adding one more case to the literature we aimed to emphasize the probable etiologic causative role of echinococcus infection in MALT lymphoma.
