BACKGROUND: Inherited epidermolysis bullosa (EB) encompasses 4 major types and at least 23 clinically distinctive phenotypes. Although considerable variability in cutaneous disease activity is known to exist within each, severity and anatomic distribution of skin lesions remain the major criteria used for subclassification. OBJECTIVE: We sought to generate accurate anatomic "density" diagrams depicting the relative extent and location of skin lesions within each major EB subtype. METHODS: Diagrams were created for each major EB type, on the basis of medical history and physical examination findings obtained from 1986 to 2002 from 3280 consecutive enrollees in the National EB Registry. RESULTS: An anatomic diagram was created for each of the major EB subtypes, representing a prototypic composite photograph of cutaneous disease activity. CONCLUSIONS: Marked variability exists in the extent of skin involvement within each major EB subtype. The use of these diagrams, generated from the world's largest cohort of patients with EB, should assist the clinician in more accurately subclassifying newly encountered patients.
