POEMS/Crow-Fukase syndrome is a rare multisystem disorder associated with elevated vascular endothelial growth factor (VEGF), which clinically presents with polyneuropathy, organomegaly, endocrinopathy, Mprotein, and skin changes. We report a case of POEMS syndrome due to a gammopathy of undetermined significance with thrombocytosis, vitamin B12 deficiency, highly elevated VEGF and in addition to glomeruloid angiomas two previously undescribed proliferative vascular lesions: a spinal arteriovenous fistula and a plexogenic pulmonary arteriopathy, which ultimately resulted in lethal pulmonary hypertension. We assume that the high VEGF levels caused the vascular abnormalities observed in our patient.
