A review of autopsies of 107 young children with pneumonia showed that 15 children (14%) had adenovirus infections, the diagnosis being based on characteristic histopathological and ultrastructural features in the lungs. Eleven (73%) of the cases of adenovirus infection followed on measles infection, and it is suggested that some became infected with adenovirus after admission to hospital. A review of clinical aspects revealed no unique features. Histopathological examination of tissues showed a common picture of necrotising bronchopneumonia, with minor degrees of rental tubular damage, infiltrates of large mononuclear cells in spleen and nodes, and an absence of lymphoid germinal centres. On light microscopy, "rosette" and "smudge" cells were seen in these cases, and two patterns of virus particle distribution in infected cells were seen ultrastructurally. It is postulated that "smudge" cells contain numerous crystalline viral arrays.
