We herein report a 56-year-old Japanese woman who was pointed out to have a space occupying lesion in the left lateral segment of the liver. Hepatitis viral-associated antigen antibody was negative and liver function tests including lactic dehydrogenase peripheral blood count tumor markers and soluble interleukin-2 receptor were all within normal limit. Imaging study using computed tomography and magnetic resonance imaging were not typical for hepatocellular carcinoma cholangiocarcinoma or other metastatic cancer. Fluorodeoxyglucose-positron emission tomography examination integrated with computed tomography scanning showed high standardized uptake value in the solitary lesion in the liver. Under a diagnosis of primary liver neoplasm laparoscopic-assisted lateral segmentectomy was performed. Liver tumor of maximal cm in diameter was consisted of aggregation of lymphocytes of predominantly B-cell containing multiple lymphocyte follicles positive for CD10 and bcl-2 consistent with a diagnosis of HPL rather than MALT lymphoma although a definitive differentiation was pending. The background .
