I have reviewed your case. There appear to be a mixed infiltrate of lymphoid cells, plasma cells, eosinophils and histiocytes. The CD138 may have not worked, it should have highlight the plasma cells. Because of the mixed infiltrate and the T cells are a mixed CD4 and CD8 cells, i think it is important to rule out infection, drug reaction and autoimmune disorder despite the fact that the pattern appears to be infiltrative. Some large cells may be residual hepatocytes. A marker for the hepatocytes will confirm that (the negative image of the lymphocyes may sometime better appreciated). In any event, I do not think that the disease in the liver can be explained by Hypereosinophilic syndrome because the predominant cell components in the liver is not eosinophils but lymphocytes.
