Congenital localized absence of the skin as a manifestation of epidermolysis bullosa.

BACKGROUND

Congenital localized absence of the skin has been observed in various subsets of inherited epidermolysis bullosa. Through electron microscopy and immunomapping, we attempt to clarify the relationship of congenital localized absence of the skin lesions to epidermolysis bullosa.

OBSERVATIONS

The case of a child with epidermolysis bullosa simplex and congenital localized absence of the skin is presented. Electron microscopy and immunomapping of the areas of congenital localized absence of the skin and sites of skin fragility suggest that these lesions are pathogenically identical.

CONCLUSION

After reviewing the literature, we believe that the term Bart's syndrome should be used to identify patients with any type of epidermolysis bullosa who present with localized congenital absence of the skin on the extremities.
