To the Editor.—
Prystowsky and Gilliam (Arch Dermatol 112:837-838, 1976) described a case that they labeled as "benign chronic bullous dermatosis of childhood," in which IgA was found deposited in a linear pattern along the dermoepidermal junction. The authors cited "the absence of a granular immunofluorescent pattern" as one factor that "excluded" the diagnosis of dermatitis herpetiformis. Since linear deposition of IgA at the dermoepidermal junction may be seen in 12% of biopsy specimens taken from adults with dermatitis herpetiformis,1 this particular finding by no means excludes this diagnosis. As the authors point out, there is much confusion regarding the nosology of bullous diseases in childhood. The interesting finding of Prystowsky and Gilliam adds to this confusion.
