Epidermolysis bullosa junctionalis progressiva in three siblings.
Three siblings of Swiss origin with epidermolysis bullosa junctionalis progressiva are described. The following clinical features were present from school age: dystrophy of the nails, non-scarring blistering of the skin, mild skin atrophy, hypodontia and dental caries. Light microscopy showed subepidermal blistering. Direct immunofluorescence was negative. On indirect immunofluorescence staining of a fresh spontaneous blister, bullous pemphigoid antigen and laminin were localized to the blister roof, and collagen IV and collagen VII to the blister base, indicating junctional splitting. Electron microscopy revealed a normal dermo-epidermal junction zone, including normal hemidesmosomes. There were no deposits of electron-dense amorphous material.
