Clinically, hemangiomas are a type of benign tumor that mostly require medication, surgery, or local treatments to regress. In rare cases, hemangiomas can regress spontaneously, especially when they are small and the underlying cause of the hemangioma has been removed. Then, the color of the hemangioma may change from its original dark red to a bright red, and gradually change to a color similar to that of normal skin, indicating that the hemangioma has regressed. Clinically, depending on the impact of the hemangioma on the patient, treatment options can include medication, local microwave therapy, laser treatments, or surgical removal.
