4 Recent classification depends on the level of tissue cleavage following trauma5, there are three major subtypes; EB simplex where cleavage is intraepidermal, it appears at birth with bullae formation limited to hands and feet that heal without scaring6, dystrophic EB where splitting is at sub lamina densa with bullae formation on feet, ankles, elbows and hands with absent or dystrophic nails and oral lesions that healed with scars, junctional EB the cleavage at lamina lucida , lesions appear at birth bullae and erosions formed which healed with scars on hands and feet with dystrophic nails and oral lesions.
Ideally, the basement membrane must contain a lamina lucida and a lamina densa.
In 1928, Pasini described a single family whose EB was distinguished by the presence of numerous white papules that he called 'albopapuloid' lesions Ultra structurally; the level of blistering or tissue cleavage in all dystrophic forms of EB is immediately below the lamina densa of the epidermal basement membrane, at a site normally occupied by anchoring fibrils.
