Recognition and Management of Ulcerative Infantile Hemangioma: Risk Factors, Diagnosis, and Prognosis.

Infantile hemangioma (IH) is a benign tumor that appears in the first year of life and typically involutes within 3 to 4 years. Ulcerative IH, the most common complication, poses a significant burden to patients. Early referral of high-risk cases reduces morbidity. Current literature on risk factors and prognosis is limited. Segmental and mixed IH in urogenital, head, neck, and lip areas show higher ulceration risk. Diagnosis is typically clinical; histopathology is rarely performed. Atypical cases require positive glucose transporter-1 immunohistochemistry. Larger lesions, delayed intervention, and bacterial infection worsen prognosis, prolong healing, and increase recurrence. Condition-dependent treatments, including oral propranolol (starting at 1 mg/kg or less daily, maintenance at 2 to 3 mg/kg daily), timolol prophylaxis, and wound management care combined with laser therapy, shorten therapy duration and minimize recurrence. Empiric antibiotics are indicated for infected ulcerative IH. Surgery is indicated for life-threatening cases (eg, chest wall hemangiomas requiring transfusion or airway obstruction) and high-morbidity cases (eg, lip lesions affecting speech or periorbital lesions impairing vision). The Infantile Hemangioma Referral Score helps clinicians identify high-risk patients who require prompt referral, thereby preventing delayed treatment.
