The authors present the results of an autopsy of a 67-year-old Japanese man with POEMS/Takatsuki/Crow-Fukase syndrome (P/T/CFS) diagnosed in 1972. Each component of the syndrome was gradually recognized after the resection of lumbar vertebral solitary plasmacytoma in 1967. The patient died in 1989 of generalized infection and renal failure. Autopsy revealed in the vertebral canal between the fifth and seventh thoracic vertebrae dorsal pachymeningeal fibrosis, with prominent amyloid deposition that oppressed the spinal cord. This condition was consistent with the final neurologic manifestation of the patient, bilateral motor and sensory disturbance below the sixth thoracic level. Myelopathy remained clinically unnoticed because neurologic disturbance had begun as peripheral polyneuropathy. Normocellular marrow with heterogeneously scattered lambda light chain-positive plasma cells and degeneration of the myelinated fibers of sciatic nerve also were observed. This is the first report of focal spinal amyloidosis associated with P/T/CFS.

A patient was admitted for fever and acute respiratory failure (ARF), rapidly progressive tetraparesis, delirium, behavioral abnormalities, and diplopia. Leukocytosis and a rise in C-reactive protein were present. A syndrome of inappropriate anti-diuretic hormone secretion (SIADH) was also diagnosed. Lumbar puncture yielded colorless CFS with mononuclear pleocytosis and protein rise. Electrodiagnosis revealed demyelinating polyneuropathy and axonal degeneration. Serum IgG and IgM for mycoplasma pneumoniae (MP) was consistent with acute infection, and erythromycin was started with rapid resolution of symptoms. Contrarily to most reports, an associated respiratory disease was not present and SIADH in association with MP has been reported only once, in a patient without direct central nervous system (CNS) involvement. Differential diagnosis and possible pathogenic mechanisms are discussed.

Crow-Fukase syndrome is diagnosed based on the presence of chronic sensori-motor polyneuropathy along with other characteristic generalized symptoms denoted by the acronym of POEMS which stands for polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes. In this syndrome, the serum levels of the vascular endothelial growth factor (VEGF) are abnormally elevated, and this is a predictive factor for its diagnosis. Although the causes of CFS/POEMS remain unknown, VEGF is evidently correlated with its pathogenesis. Human glioblastoma cells are known to express VEGF. In models of CFS/POEMS, mice that are peritoneally transplanted with human glioblastomas exhibit high serum levels of VEGF, prominent edema with increased circulation volume, and pathological findings in the liver, spleen, and kidney. VEGF that is highly concentrated in platelets may be released in massive amounts due to coagulation in the peripheral tissue and may thus exert its maximal physiological effects and produce the abovementioned diffuse pathological findings. The correlation between polyneuropathy and elevated VEGF remains unclear. However, VEGF may affect the blood-nerve barrier by increased microvascular hyperpermeability, upregulated cytokines such as matrix metalloproteases may induce blood-nerve barrier breakdown and demyelination of the peripheral nerve. Furthermore, microangiopathy due to proliferative endothelial cells and hypercoagulated occlusion also affect axonal damage. Novel strategies that have recently been proposed for the management of this disease include high-dose chemotherapy combined with autologous peripheral blood stem cell transplantation (PBSCT) and molecular-targeted therapy against plasma cells and VEGF. Notably, PBSCT exerts a dramatic effect on polyneuropathy; such an effect has rarely been achieved by the previously described modalities of low-dose melphallan and steroid therapy. PBSCT is observed to induce a rapid and persistent decrease in the serum VEGF levels. In conclusion, VEGF is not only the primary molecule involved in the pathogenesis of CSF, but also an important marker for both the diagnosis and treatment of this disease.
