Among those proposed is an alteration in the chemical composition and physical properties of the connective-tissue ground substance,1 which is also considered to be the basis of many of the connective-tissue disorders.2 Evidence of a causal relation beween the so-called "collagen diseases" and amyloidosis is supported by the frequent association of the latter with rheumatoid arthritis.3 The concurrence of two rare diseases, dermatomyositis and generalized amyloidosis, prompted this report.
