Clinicopathological features of eight Korean cases of primary hepatic lymphoma.
Primary hepatic lymphoma is very rare, accounting for less than 0.4% of extranodal lymphomas. Furthermore, hepatic lymphoma, either primary or metastatic, is infrequently confirmed histopathologically in needle biopsy specimens. The aim of the current study is to assess the clinicopathological characteristics of primary hepatic lymphomas in Korea, which is an endemic area of chronic B viral hepatitis. In total, 17 cases with liver needle biopsy specimens with involvement of malignant lymphoma, from whom eight cases met the criteria for primary hepatic lymphoma, were selected. The clinicopathological features were reviewed. Five of eight (62.5%) cases were T cell lymphoma, including three cases (37.5%) of hepatosplenic T cell lymphoma. Three cases (37.5%) were diffuse large B cell lymphomas. Seven patients had follow-up data from 25 days to 50 months that was available for evaluation. The partial remission was present in two of seven patients (28.6%) and five patients (71%) died of disease 25 days to 7 months after the diagnosis. The data indicate that the relatively high incidence of T-cell type in Korean cases of primary hepatic lymphoma may be related to its aggressive behavior and poor prognosis despite combination chemotherapy.
