Some years ago Czerny gave the name of "Exudative Diathesis" to a group of symptoms characterized by an exudation into the skin and mucous membranes. The skin of infants suffering from exudative diathesis shows some form of eczema, varying in grade from a very mild seborrhea to extensive infiltration, with excoriation. The so-called geographic tongue is seen in some cases. Catarrhal affections of the respiratory tract—coryza, pharyngitis, recurrent bronchitis, and asthma—make their appearance. A catarrh of the gastrointestinal tract is often present. General glandular enlargement with an enlarged spleen may be combined with one or more of the other manifestations. An eosinophilia is found in the blood examination of some of the cases. The exudative diathesis is generally encountered either in very obese or in very thin infants; some of the cases, however, are normal in weight and development.
