A multidisciplinary case report of multiple myeloma with renal and cardiac involvement: a look beyond amyloidosis.

This case highlights that multiple organ involvement in patients with MM may result from a combination of paraprotein-dependent and -independent factors. Moreover, renal diseases induced by monoclonal gammopathies are a group of complex and heterogeneous disorders. Their subtle presentation and their potential multiorgan involvement require the expertise of a multidisciplinary team able to provide the most appropriate diagnostic and therapeutic assessment.
