Few preliminary reports studied the utility of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) for differentiation between infantile hemangiomas (IHs) and vascular malformations. The aim of this study was to investigate the role of serum VEGF and bFGF levels in differentiating IHs from vascular malformations and identifying the stage and clinical course of IHs. Serum levels of VEGF and bFGF were assessed in 60 infants and children with various cutaneous vascular anomalies defined in 3 groups: proliferating IHs (n = 25), involuting IHs (n = 23), and vascular malformations (n = 12), in comparison with their levels in 40 healthy matched control. Serum levels of VEGF and bFGF were significantly elevated in all groups as compared to control ( P &lt; .001, respectively). Both proliferating and involuting IHs had comparable levels of both markers ( P &gt; .05, respectively) that were significantly higher in comparison with vascular malformations ( P &lt; .05, respectively). Significantly lower VEGF levels were found in IHs that had regressed spontaneously (n = 11) compared to those regressed by treatment (n = 37), ( P &lt; .05); meanwhile, bFGF showed no significant difference between both groups ( P &gt; .05). Using receiver operating characteristic curves, a combined use of VGEF and bFGF yielded a sensitivity of 85.42% and a specificity of 100% for differentiating IHs from vascular malformations. Serum VEGF and/or bFGF levels are increased in cutaneous vascular anomalies and can differentiate IHs from vascular malformations. None of these markers could help in identifying the stage of IHs. Low VEGF is associated with spontaneous regression of IHs.
