Caractéristiques communes
Neuropathies associated with monoclonal proteins occur in monoclonal gammopathy of undetermined significance, multiple myeloma, Waldenström macroglobulinemia, amyloidosis, and other hematologic malignancies.
Bilan étiologique
MGUS
Hémopathies malignes
IgG: myélome-plasmocytome
IgM: syndrome lymphoprolifératif (lymphome malin)
- Leucémie lymphoïde chronique
- Maladie de Waldenström (lymphome lymphoplasmocytaire)
Amyloïdose
- Souvent lambda
POEMS
(polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes)
- Souvent IgG/IgA et lambda
- POEMS syndrome is characterized by the presence of a monoclonal plasma cell disorder, peripheral neuropathy, and one or more of the following: osteosclerotic myeloma, Castleman disease (angiofollicular lymph node hyperplasia), elevated serum vascular endothelial growth factor, organomegaly, endocrinopathy, edema, typical skin changes, and papilledema.
