Monoclonal Gammopathy-Associated Neuropathy.

Objective: Peripheral neuropathy (PN) is more commonly seen in individuals with monoclonal gammopathies, especially in patients with an IgM monoclonal gammopathy or Waldenström macroglobulinemia.

Results: There are multiple potential ways that the paraprotein may result in peripheral neuropathy. The diagnosis and management of monoclonal gammopathy-associated PN are challenging and necessitate a concerted effort between the hematologist/oncologist and the neurologist. This review describes the most common PN syndromes associated with monoclonal gammopathy, such as anti-myelin-associated glycoprotein neuropathy, light chain amyloidosis, cryoglobulinemia, POEMS, CANOMAD, and others. We also review the therapies used to treat these conditions.
