Three children with plasma cell granuloma of the lung had a syndrome characterized by digital clubbing, roentgenographic evidence of an intrapulmonary lesion with a diverse configuration, elevated erythrocyte sedimentation rate, elevated serum immunoglobulin levels, and thrombocytosis.

The difficulty of diagnosing pneumonia by chest x-ray in children less than 4 years of age was studied by comparing the chest roentgenograms of 34 healthy children with the chest roentgen ograms of 34 children previously diagnosed as having pneumonia. Review of these films without knowledge of the previous interpretation and without clinical information disclosed variations regarding the roentgenographic confirmation of pneumonia in 24 percent of the cases and variations regarding the location of the lesion in about 50 percent of the cases.
