[Major hypoproteinemia revealing enteritis caused by Yersinia enterolytica and cytomegalovirus at the onset of chronic lymphocytic leukemia].

We report the first case of probable protein-losing enteropathy revealing a cytomegalovirus/Yersinia enterolytica infection at the onset of a chronic lymphocytic leukaemia. Severe hypoprotidaemia, digestive tract yersiniosis, ulcerative and microgranulomatous enteritis with a large number of cytomegalic inclusions in mucosal cells, and incipient lymphoid proliferation were the most characteristic findings.
