The child has a hemangioma on their foot, and parents can temporarily observe it as some hemangiomas may heal on their own, so there is no need to rush into treatment. Moreover, a hemangioma on the foot usually does not affect the child's health, as it is neither itchy nor painful, and it does not affect the appearance either.

If the hemangioma grows very rapidly, and it has not receded by the time the child is five years old, consider using injections of sclerosing agents or surgical treatment options to remove the hemangioma.

If the hemangioma is small and not growing rapidly, parents may not need to undertake any special treatment, as a hemangioma on the foot does not affect the body nor does it impact appearance.

The difference between granuloma and hemangioma

Granulomas and hemangiomas are both relatively common in clinical settings, yet they have fundamental differences. A granuloma often refers to the proliferation of macrophages and their derivative cells following inflammation in tissues or organs, forming a nodule known as a granuloma, which is actually caused by the inflammation. Hemangiomas, on the other hand, are usually tumors that form from the proliferation of blood vessel-forming cells during embryonic development, and they have no significant relationship with inflammation. Hemangiomas are also a type of benign tumor, which is the main difference between the two.

How are hemangiomas formed?

The etiology of hemangioma is unknown. Studies have shown that the use of progesterone during pregnancy, undergoing chorionic villus sampling, hypertensive disorders during pregnancy, and low birth weight at the time of birth may be related to the formation of hemangiomas. It is believed that hemangiomas are a result of minor misconfigurations in the control gene segments during the embryonic development process, particularly during the early stages of vascular tissue differentiation. This leads to abnormal tissue differentiation at specific sites, eventually developing into hemangiomas. During the early months of embryonic development, from eight to twelve months, mechanical damage to embryonic tissue and local bleeding can cause some hematopoietic stem cells to be distributed among other embryonic cells, some of which differentiate into vessel-like tissues and ultimately form hemangiomas.

Can hemangiomas go untreated?

The severity of harm varies with different types of hemangiomas, such as in adults with mixed-type hemangiomas. These can continually develop as the patient ages. If the affected areas expand further, they may extend to tissues and organs like the eyes, nose, lips, or ears. These organs might then become covered by the expanding vascular tissue, potentially causing impairments in functions such as breathing, eating, vision, and hearing. If hemangiomas appear on the limbs, they can also lead to dysfunction, affecting mobility. Therefore, it is advisable to seek treatment for hemangiomas as early as possible.

What should I do if my child has a hemangioma?

Infantile hemangiomas are caused by congenital genetic defects leading to abnormal development of capillaries. Currently, there are no very effective treatments available, and the method of treatment can be chosen based on the size and severity of the hemangioma. If the hemangioma is relatively small and does not affect the child's body, it can be temporarily observed, as some children's hemangiomas may gradually heal on their own. If the hemangioma is larger, or has caused some related clinical symptoms, or has affected the child's appearance, it is advisable to consider going to a regular hospital for surgical removal. Postoperative prognosis for the child is generally good, and ideal treatment results can be achieved.

Causes and Treatment of Infantile Hemangiomas

Infantile hemangiomas are usually caused by congenital factors, and the pathogenesis and specific causes of hemangiomas are not very clear at the moment. Since there is a certain possibility that infantile hemangiomas can heal on their own, if the hemangioma's location is not very noticeable and not particularly significant, it is advisable to initially observe it. If the hemangioma has not healed on its own by the time the child turns five, consideration can be given to treat it with sclerosing injections or through surgery. If the hemangioma is located in an internal organ and does not severely affect the child's health under normal circumstances, it could still be quite dangerous if it bursts. Therefore, parents should give it enough attention.
