The department for treating infantile hemangioma should be determined based on the location, size, and severity of the hemangioma.

If the hemangioma is located on the surface of the body, it is generally appropriate to consult the department of plastic and cosmetic surgery. If the hemangioma is on the face, the oral medicine department should be visited. If the hemangioma is around the eyes, then the ophthalmology department should be consulted. If the hemangioma is internal or if there are other concurrent tumorous diseases, it may be necessary to visit the pediatric hematology-oncology department or the corresponding surgical department. This would be the most appropriate and correct choice.
