POEMS syndrome: an unusual cause of exuberant callus formation


Several growth factors are expressed in distinct temporal and spatial patterns during fracture repair. Together, they lead to angiogenesis–osteogenesis coupling and hence bone healing by callus formation. Of these growth factors, vascular endothelial growth factor is of particular interest because of its ability to induce neovascularisation (angiogenesis) and osteoclast invasion in soft callus. Hyperplastic callus can be seen in metabolic bone disease, endocrine disease and in patients with traumatic brain injury, but has not been described so far in polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes (POEMS) syndrome. This report is a case of POEMS syndrome with unusual presentation in the form of exuberant callus formation at fracture sites.
