We report 2 cases of primary systemic amyloidosis. A monoclonal gammop
athy was confirmed at the postmortem examination of the first patient.
An extensive search for evidence of chronic infection, inflammation,
neoplasms and paraproteinemia was conclusively negative in the other p
atient. The recognition of cutaneous signs of primary systemic amyloid
osis is crucial to insure a rapid management aimed at postponing the f
atal issue of the disease.
