As part of the workup of polyneuropathy, neurologists often encounter patients with paraproteinemias, also called monoclonal gammopathies. Given the relatively rising prevalence of both polyneuropathy and paraproteinemias in our aging population, this coexistence is frequently due to chance. Still, certain types of paraproteinemias have a well-defined causal role in the development of polyneuropathy, and therefore has implications in their subsequent work-up and management. Once a monoclonal gammopathy has been deemed as “benign” or of undetermined significance, looking at the heavy chain subtype is paramount in deciding whether it is related to a polyneuropathy. Conversely, polyneuropathies associated with monoclonal gammopathies tend to have a distinct clinical, serological, and/or electrodiagnostic phenotype that helps in establishing an association. Recognizing this association will determine approp riate workup and management.
monoclonal gammopathy
Síndrome de POEMS, reporte de un caso con doble patrón monoclonal.
POEMS síndrome is an uncommon multisystemic paraneoplastic disorder characterized by the presence of a predominantly motor polyneuropathy associated with other manifestations like organomegaly, endocrinopathy, monoclonal gammopathy and skin changes. We report a case of a 36 years old female with diagnostic criteria for this disorder, and a particular double monoclonal pattern IgG and IgA type., demonstrated by immunofixation.
