Early identification of infantile hemangioma is mainly based on clinical manifestations, followed by histopathological examination, ultrasound examination and magnetic resonance examination. 1. Clinical manifestations. Typical symptoms of infantile hemangioma are strawberry-like plaques on the skin surface, or light red or purple-red irregular plaques of different sizes, with soft texture and discoloration when pressed. 2. Histopathological examination is mainly used to understand the pathological nature of hemangioma and distinguish benign and malignant. 3. Ultrasound examination is mainly used to understand the size and blood supply of infantile hemangioma, and to exclude the possibility of heart disease and liver hemangioma. 4. Magnetic Resonance Imaging (MRI) is mainly to find out whether the infantile hemangioma affects the surrounding tissues. Since some infantile hemangiomas do not show obvious clinical manifestations in the early stage, it is necessary to ask the doctor for an interview to confirm the diagnosis.
