• We describe a child who began developing subepidermal blisters in the recipient sites of split-thickness skin grafts; this process has continued for almost a year and continues to spare nongrafted skin. Routine histologic and immunofluorescence mapping studies demonstrated this disorder to be a relatively noninflammatory one characterized by sub-lamina densa blister formation. Results of direct immunofluorescence were negative. By electron microscopy, anchoring fibrils were sparse in number and in some areas appeared malformed; otherwise, the basement membrane zone was morphologically unremarkable. Bullous pemphigoid antigen, laminin, type IV collagen, epidermolysis bullosa acquisita antigen, and LDA-1 were all normally expressed along the dermoepidermal junction. In contrast, KF-1 antigen was absent. These findings suggest a disease process confined to skin graft recipient sites with features identical to those previously described with recessive dystrophic or immunofluorescence-negative acquired epidermolysis bullosa.
