[Amyloidosis in plasmacytic myeloma with dominant manifestations of joint involvement]

The authors describe a case of plasmocytic myeloma complicated by the development of systemic amyloidosis. The symptoms were dominated by marked macroglossia and arthropathy which by the objective finding and subjective manifestations imitated rheumatoid arthritis. In the discussion the authors emphasize general manifestations of amyloid arthropathy.
