Abstract:
Background and Aims: Waldenström's Macroglobulinemia (WM) associated neuropathy is frequent. However, it can have different etiologies leading to different treatments, which makes the diagnosis challenging for the clinician. Methods: Case study. Results: We report the case of a 71-year-old female who presented a severe painful sensory motor axonal neuropathy. She had an IgM lambda monoclonal gammopathy with bone marrow and pleura lymphoplasmocytic cell infiltration, in favor of WM. The neuropathy worsened despite two lines of hematologic treatment. Nerve biopsy showed diffuse infiltrates of B and T cells with a B cell amplification confirmed on polymerase chain reaction based clonality testing. Interpretation: Nerve biopsy is a key tool in the diagnosis of WM associated axonal neuropathy, especially for tumoral nerve infiltration since other classical investigations are often negative. The pathogenesis of this infiltration is debated, but our data are in favor of a hematogenic invasion by tumoral cells. Neuropathy secondary to tumoral nerve invasion may worsen in spite of good hematological response to treatment.
