Аннотация
BACKGROUND: Pleural effusion caused by varicella-zoster virus (VZV) is rare. We report a case of a woman with acute lymphocytic leukemia (ALL) who developed a pleural effusion caused by VZV infection.
CASE: A 55-year-old woman with ALL treated with consolidation therapy developed skin vesicles and a pleural effusion. Pleural fluid smears contained numerous mesothelial cells, which had ground-glass nuclei or eosinophilic nuclear inclusions. Some multinucleated giant cells were also seen. Electron microscopic examination revealed intranuclear virus particles, about 150 nm in diameter, in some mesothelial cells. Tissue samples from the skin, lungs, pleura, liver, pancreas, kidneys and gastrointestinal tract, obtained at autopsy, contained many virus-infected cells. They were positive for VZV glyco-protein 1 by immunohistochemistry.
CONCLUSION: VZV infection should be considered in the differential diagnosis of an unexplained exudative pleural effusion, especially in immunocompromised hosts.
