''Mandatory:'' | |||
;1. Polyneuropathy (typically demyelinating) | |||
;2. Monoclonal plasma cell proliferation (usually lambda) | |||
''Major:'' | |||
;3. [[Castleman disease]] | |||
;4. Sclerotic bone lesions | |||
;5. Vascular endothelial growth factor elevation | |||
''Minor:'' | |||
;6. Organomegaly (splenomegaly, hepatomegaly or lymphadenopathy) | |||
;7. Extravascular volume overload | |||
;8. Endocrinopathy | |||
;9. Sking changes | |||

POEMS syndrome is unusual in causing osteosclerotic bone deposits, so-called osteosclerotic myeloma, in contrast to the lytic lesions seen in more conventional [[plasma cell myeloma]]. | |||
