Epidermolysis bullosa hereditaria letalis.

Abstract
A patient [an infant] with epidermolysis bullosa hereditaria letalis had the characteristic EM lesions not only in the skin, but also in the gastrointestinal, genito-urinary and respiratory tracts. Administration of dexamethasone to this patient resulted in a significant decrease in the blistering. Although the patient died, long term survival in this disease is not rare. Staining tissue specimens from patients with epidermolysis bullosa with fluorescein-labeled bullous pemphigoid antibody is a reliable method for differentiating between junctional and dystrophic disease.
