We describe a case of fatal systemic amyloidosis presenting with mucocutaneous bullous lesions in a patient with IgA kappa monoclonal gammopathy. The amyloid plaques were composed of an unusual mixture of immunoglobulin kappa light chain and amyloid A proteins. Whereas oesophageal and oropharyngeal blisters are known to occur in several types of bullous dermatoses, to our knowledge this is the first report of oesophagopharyngeal blisters complicating bullous amyloidosis.
