POEMS syndrome is a constellation of findings, best thought of as a paraneoplastic syndrome due to clonal plasma cells:[1]
- Polyneuropathy.
- Organomegaly.
- Endocrinopathy.
- M-protein.
- Skin changes.
Diagnostic criteria requires both mandatory criteria and at least one each from major and minor criteria:[2] 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 10. Papilloedema 11. Thrombocytosis/polycythemia
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.
Pathology
- The pathologist may come across an undiagnosed case in the form of a glomeruloid hemangioma; however, glomeruloid hemangiomas are not always associated with the POEMS syndrome.[3]
