Although the morphological features of hepatitis C virus(HCV)recurrence after orthotopic liver transplantation(OLT)have been well established in the last decades,the differential diagnosis still represents a challenge for the pathologist,especially early recurrent hepatitis C vs mild acute cellular *** present review focuses on the role of the pathologist and the pathology laboratory in the management of recipients with recurrent hepatitis C,the usefulness of early and late post-OLT liver biopsies,and the potential role of ancillary techniques(immunohistochemistry and reverse transcription-polymerase chain reaction,RT-PCR).The English literature on the topic is reviewed,focusing on the histopathology,the immunohistochemistry and the use of RT-PCR on HCV-positive post-OLT *** different histopathological illustrations of early and chronic recurrent hepatitis C are presented,with special focus on the main differential diagnoses and those features with prognostic relevance(cholestasis above all).The usefulness of ancillary techniques are discussed,especially HCV RNA quantitation by ***,the usefulness of long-term protocol biopsies is addressed:their usefulness for the study of allograft disease progression is clear,but their meaning in the long term is still *** significance of plasma cell infiltrate in HCV-positive allografts,the prognostic weight of graft steatosis,and the impact of donor age in recurrent hepatitis C also represent additional open issues.
