ABSTRACT
Infantile Hemangiomas (IH) correspond to one of the most frequent dermatological disorders in pediatric age, with a prevalence of between 4 and 10 % of all newborns. Its origin is theorized from a proliferative response of vascular cells to angiogenic stimuli. Since 2014, the Food and Drug Administration (FDA) has approved the use of propranolol as a first-line medical therapy for the therapeutic management of these lesions, and although multiple clinical trials continue to be carried out, other beta blockers have not been shown to be superior to this medication. In this case, it’s a female infant, with no apparent significant history, who presented a hemangioma that encompassed the entire right orbit, and which caused eyelid ptosis of mechanical origin, in whom treatment with propranolol was started at a dose of 1 mg/kg/day. The lesion regressing almost in its entirety 10 months after starting the treatment. The use of propanol has improved the prognosis of patients with hemangiomas, reducing the rate of surgery and associated. Propranolol induces regression of hemangioma cells through inhibition of Vascular Endothelial Growth Factor A (VEGF-A), mediated by the Hypoxia-Inducible Factor 1α (HIF 1α) pathway. Possible adverse effects associated with its beta blocker mechanism must be closely monitored, but it is considered the first pharmacological option for the management of these lesions.REFERENCES
