Giant cell pneumonia associated with parainfluenza virus type 3 infection and chronic poliovirus type 2 meningoencephalomyelitis are documented in an infant with combined immunologic deficiency (Swiss type). Caution should be exercised in attributing cases of giant cell pneumonia to measles virus without serologic or virologic evidence.

Giant cell pneumonia is a rare and uncommon type of lung infection developing as a complication of measles, especially in immunocompromised patients, whether their immune systems are affected primarily or whether they have acquired immune defects. As well as being uncommon, it is also atypical because of absence of the characteristic rash and of absent or low antibody titers against measles in most of the cases. It is known that cellular immunity is more important than humoral immunity in the host response to measles, so hypogammaglobulinemic patients with normal cellular immunity usually recover uneventfully from measles and also have the characteristic rash. We report a case with giant cell pneumonia that was confirmed by postmortem histopathological examination. We especially want to point out that even in the absence of rash, with the clinical and radiological features of pneumonia, measles should be considered in a patient, whether in remission or not, receiving immunosuppressive treatment.

Giant cell pneumonia secondary to human parainfluenza virus 3 has been reported only rarely in immunocompromised hosts. The few cases documented after bone marrow transplant have resulted in significant morbidity and mortality. To our knowledge, this entity has not been described following umbilical cord blood transplant. Pulmonary alveolar proteinosis, a rare condition that has been reported with increasing frequency in association with immunocompromise and infections, has not been documented in the setting of either umbilical cord blood transplant or human parainfluenza viral infection. We report what we believe is the first documented case of giant cell pneumonia caused by human parainfluenza virus 3 in an umbilical cord blood transplant recipient. To our knowledge, a unique associated feature of this case, a pulmonary alveolar proteinosis-like reaction, has not been reported previously in association with human parainfluenza virus pneumonia.
