A 13-month-old boy had irregularly shaped, erythematous to dusky red, slightly raised patches and plaques on the left antecubital fossa and arm for 7 months. The lesions were firm and tender. Histopathologically the lesion consisted of small, circumscribed, angiomatous tufts and lobules with a cannonball appearance scattered throughout dermis, a characteristic feature of tufted angioma. For 15 weeks, interferon-α intralesional injections have been performed and the lesions showed an improvement.
