POEMS syndrome

POEMS syndrome
Other namesCrow–Fukase syndrome, Osteosclerotic myeloma, PEP syndrome, Polyneuropathy-endocrinopathy-plasma cell dyscrasia syndrome, Takatsuki syndrome.[1]
Plasma cells
Multiple myeloma is usually diagnosed because malignant plasma cells continue to produce an antibody that can be detected as a paraprotein.

POEMS syndrome (also termed osteosclerotic myeloma, Crow–Fukase syndrome, Takatsuki disease, or PEP syndrome) is a rare paraneoplastic syndrome caused by a clone of aberrant plasma cells. The name POEMS is an acronym for some of the disease's major signs and symptoms (polyneuropathy, organomegaly, endocrinopathy, myeloma protein, and skin changes), as is PEP (polyneuropathy, endocrinopathy, plasma cell dyscrasia).

The signs and symptoms of most neoplasms are due to their mass effects caused by the invasion and destruction of tissues by the neoplasms' cells. Signs and symptoms of a cancer causing a paraneoplastic syndrome result from the release of humoral factors such as hormones, cytokines, or immunoglobulins by the syndrome's neoplastic cells and/or the response of the immune system to the neoplasm. Many of the signs and symptoms in POEMS syndrome are due at least in part to the release of an aberrant immunoglobulin, i.e. a myeloma protein, as well as certain cytokines by the malignant plasma cells.[9][3][4]

POEMS syndrome typically begins in middle age – the average age at onset is 50 – and affects up to twice as many men as women.
