Eczema is a term frequently applied to totally unrelated dermatoses of infancy and childhood. The confusion which exists as to the pathogenesis of this condition in the age groups mentioned was clearly demonstrated at the pediatric congress held in Germany in 1929. While certain phases of eczemas in adults were admitted to have many points in common with those of later childhood, it was thought that the eczemas of infancy and early childhood composed a group apart.
It seemed to us that part of this confusion was due to the inclusion of unrelated dermatoses in this group of eczemas, and it seems logical that first a clear conception of eczema from the clinical standpoint should be obtained. A step forward is the separation from eczema of dermatoses such as seborrheic dermatitis and intertrigo which are usually, but erroneously, included under this term.
The seborrheic dermatosis of Unna is seldom found
