VEGFA and polyneuropathy: The proximal weakness led to ruling out the possibility of POEMS (Polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes), the electromyography showed no polyneuropathy, another laboratory was performed, the Vascular Endothelial Growth Factor (VEGF), 103.4 pg/mL (VR: < 128.9 pg /mL), which was negative, ruling out the possibility of POEMS.
