[An autopsy case of primary hepatic malignant lymphoma and a review of 10 reported cases].

Primary malignant lymphoma is an extremely rare neoplasm in the liver, with only 10 cases having been reported in the English literature. An autopsy case of primary hepatic lymphoma is presented herein. Although a few lymph nodes were slightly involved, large involvement of lymphoma was apparent in the liver. This lymphoma was classified as a diffuse large-cell (histiocytic) type. Microscopically, the PAP method for immunoglobulin showed positive staining of IgG and lambda in the lymphoma cells.
