title: Hepatocellular carcinoma with lymphoid stroma: a tumour with good prognosis after liver transplantation.
abstract: OBJECTIVE
  Carcinomas with lymphoid stroma arising in non-liver-organs have a better prognosis than other carcinomas and may be associated with Epstein-Barr virus. We determined the frequency, characteristics and prognosis of hepatocellular carcinomas with lymphoid stroma.
  
  
  RESULTS
  Histology of the livers of 162 patients with hepatocellular carcinoma, who underwent an orthotopic liver transplantation, was reviewed independently by three pathologists. Hepatocellular carcinoma with lymphoid stroma was diagnosed when all tumour samples contained more lymphocytes than tumour cells. Epstein-Barr virus was detected by in-situ hybridization and by polymerase chain reaction. Five patients (3.6%) were classified as hepatocellular carcinomas with lymphoid stroma. All patients were males. Cirrhosis was present in four/five patients. Serum alpha-fetoprotein levels were normal. Inter-observer histological reproducibility was good. Tumour cells did not contain Epstein-Barr virus. The five patients were alive without tumour at three years, although two of them had adverse prognostic factors at the time of transplantation (more than one tumour with a diameter > or = 40 mm). Only one patient had tumour recurrence, but he survived 7.6 years post-transplantation. The 5-year survival of patients with hepatocellular carcinoma with lymphoid stroma was better than that of the patients with other types of hepatocellular carcinomas (P = 0.04).
  
  
  CONCLUSIONS
  Hepatocellular carcinoma with lymphoid stroma should be considered as a distinct clinicopathological and prognostic entity.
