Overview

The diagnosis of POEMS syndrome presents a diagnostic challenge for the physician. A thorough examination of organ systems should be attempted in order to reach a confirmed diagnosis. POEMS syndrome should be differentiated from other conditions presenting as a polyneuropathy (metabolic syndrome, vitamin B12 deficiency, Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy and multifocal motor polyneuropathy), organomegaly with lymphadenopathy (malaria, leshmaniasis or kala-azar, infective hepatitis, chronic myelogenous leukemia, lymphoma, primary amyloidosis, Gaucher's disease), endocrinopathy (hypogonadism, hypothyroidism, hypopituitarism), monoclonal plasma cell proliferation (multiple myeloma, monoclonal gammopathy of undetermined significance, plasmacytoma), mixed lytic/sclerotic bone lesions (osteomalacia, osteogenesis imperfecta) and skin changes.

Differentiating POEMS Syndrome From Other Diseases

The diagnosis of POEMS syndrome presents a diagnostic challenge for the physician. A thorough examination of organ systems should be attempted in order to reach a confirmed diagnosis. POEMS syndrome should be differentiated from other conditions presenting as a polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell proliferation, mixed lytic/sclerotic bone lesions and skin changes. The differentials include the following:

Organ System Involvement Differential Diagnosis Causes Clinical Features Laboratory Findings Gold Standard Test Therapy
P = Polyneuropathy POEMS syndrome (Demyelinating)[1]
Metabolic Syndrome (Axonal pathology)[8]
Vitamin Deficiencies (Axonal Pathology)[10]
Guillain-Barre Syndrome (Demyelinating)[16]
  • Clinical diagnostic criteria (progressive weakness of more than two limbs, areflexia, and progression for no more than four weeks)[21]
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) (Mixed axonal and demyelinatiing)[24][25]
  • EFNS/PNS criteria[33]
  • Koski criteria[34]
Multifocal Motor Neuropathy[35]
  • Progressive, asymmetric, distal and upper limb predominant weakness
  • No significant sensory abnormalities
  • Areflexia
  • Clinical criteria (EFNS/PNS):[36]
    • Slowly progressive or step-wise progressive, focal, asymmetric limb weakness; i.e., motor involvement in the motor nerve distribution of at least two nerves for > 1 month.
