Erosive amyloidosis of the wrist and knee associated with oligoclonal bands.

We report on a patient who presented with an inflammatory arthropathy clinically, though without a raised erythrocyte sedimentation rate, and in whom investigation subsequently showed erosive amyloidosis with an oligoclonal band. There was no evidence of rheumatoid disease and she has not developed any haematological malignancy. The only other case reported in the literature had an elevated erythrocyte sedimentation rate and went on to develop a lymphoplasmacytoid lymphoma.
