Complicating systemic amyloidosis in dystrophic epidermolysis bullosa, recessive type.

An autopsy case of dystrophic epidermolysis bullosa, recessive type, complicated by systemic secondary amyloidosis is described. The patient had developed multiple bullous lesions and erosions from birth, followed by repeated infection. At autopsy, chronic persistent inflammation was observed in the skin and in various visceral organs, accompanied by systemic amyloidosis. By the peroxidase-antiperoxidase (PAP) method, amyloid deposits stained positively for anti-AA-protein antiserum. In the present case, we concluded that the systemic amyloidosis was of the AA type, and developed secondarily to the chronic persistent inflammation in the prolonged course of dystrophic epidermolysis bullosa, recessive type.
