[Disseminated varicella-zoster virus infection without vesicles in a patient with malignant lymphoma].

A 76-year-old man was diagnosed as having malignant lymphoma (non-Hodgkin's lymphoma, diffuse medium cell-sized, B cell type). He was treated with CHOP therapy but with no response. In the terminal stage, he had continuous high temperature despite the administration of anti-bacterial and anti-fungal agents. Paralytic ileus, liver and pancreas dysfunction, and gastrointestinal bleeding developed. No skin eruptions occurred throughout the clinical course. He died on day 36 of treatment. Postmortem examination revealed foci of hemorrhagic necrosis containing many multinuclear giant-cells some of which with intranuclear inclusion bodies (Cowdry type A), in the liver, pancreas, gastrointestinal tract, bone marrow and other organs. Electron microscopy showed viral particles in the cytoplasm but not the nuclei of infected cells which were covered with a capsule, which was characteristic of varicella-zoster virus infection. Cells of the above organs were positive for immunohistochemical staining using antivaricella-zoster antibodies. The multiorgan failure seen in the terminal stage was considered to be due to disseminated varicella-zoster infection.
