Clinical classification of the diseases in the epidermolysis bullosa group has led to little progress toward elucidation of the mechanisms of blister formation operative in these conditions. Histologic studies, although of considerable interest, have been the source of controversy, particularly as regards the role of the elastic tissue in these diseases. Two factors seem to be responsible for most of the variance in results between different workers. The first of these is use of unsuitable specimens. In most studies, naturally occurring blisters of uncertain age, or post mortem skin was examined. Secondly, there was the limitation iii resolution imposed by use of the light microscope. In the present study attempts were made to reduce these difficulties by the exclusive use of specimens obtained from non-blistered or experimentally blistered areas, and by supplementing light microscope examinations by electron microscope observations. This approach has given data which tends to localize to some extent the site of the defects responsible for blister formation. Some cautious speculations concerning the nature of these defects can also be made. In other reports (1, 2) epidermolysis bullosa simplex blisters were shown to have developed as a result of disintegration of basal and suprabasal cells. For convenient reference an electron micrograph of a fully formed blister of epidermolysis bullosa simplex is included at the end of the Results section of this paper (Fig. 25), but primary concern is given to epidermolysis bullosa hereditaria letalis, epidermolysis bullosa dystrophica (recessive type), and porphyria cutanea tarda. A working classification of the epidermolysis bullosa group of diseases is given in Table I.
