Unusual presentation of measles giant cell pneumonia in a patient with acquired immunodeficiency syndrome.

The typical clinical presentation of measles in a normal immunocompetent host includes cough, coryza, conjunctivitis, Koplik's spots, and rash. However, in an immunocompromised host, measles may have an atypical clinical presentation and may be commonly associated with severe pneumonia or encephalitis. We report a fatal case of measles pneumonia without any clinical features that suggest measles in a patient with acquired immunodeficiency syndrome.
