[Varicella-zoster virus infection after hematopoietic stem cell transplantation].

Of 264 patients aged 15 years or more who underwent hematopoietic stem cell transplantation between 1989 and September 1998 at the Tokyo Metropolitan Komagome Hospital, 47 were infected by the varicella-zoster virus (VZV). In 2 patients, visceral disease preceded cutaneous dissemination. One of these patients exhibited gastrointestinal symptoms followed by disseminated skin rash 6 days later. In the other patient, epigastralgia developed and was followed by seizures secondary to meningitis; the appearance of a skin rash 5 days after these initial symptoms yielded the diagnosis. Early diagnosis and treatment of VZV infection are important, especially for patients who present with visceral symptoms suspected to be due to VZV.
