title: Nasal tip infantile hemangioma, a case of mistaken identity.
abstract: Infantile hemangioma is the most common vascular tumor in the pediatric population, and the majority of cases are diagnosed only on history and physical examination. This report highlights a case in which a 3-year-old girl undergoes surgical removal of what was thought to be an infantile hemangioma. Immunohistochemical staining, however, showed the absence of GLUT-1 marker, which discredited the original diagnosis. The vascular tumor was found to be a unique presentation of a pyogenic granuloma. When the clinical diagnosis is in question, referral for biopsy may prevent unnecessary medical interventions.
