Hemangioma is the most common congenital vascular disease in pediatric patients, mostly benign, with the majority of congenital cases being common pediatric tumors. The incidence of hemangioma is about 3-8%. This tumor can occur in any part of the body, with the head, face and neck being the most common, followed by the trunk, and rarely in the internal organs. The skin and subcutaneous tissues are the most common, followed by oral mucosa and muscles, and can also occur in bones, internal organs, brain and other tissues and organs. Pediatric hemangioma is a benign congenital tumor that originates from residual embryonic tissues, with marked proliferation of capillary endothelial cells and capillary dilation; it is mostly found in the skin of the head and neck, but can also occur in mucous membranes and muscles, and is often detected at birth or shortly after birth. It is often found at birth or shortly after birth. It grows rapidly in infancy, but can gradually stop growing later and sometimes can subside on its own. This disease is the most common type of soft tissue tumor. Cutaneous hemangioma is generally divided into three types: bright red nevus, grass plum-like nevus and cavernous hemangioma. Pediatric hemangiomas are characterized by rapid growth, especially in the first year of life. Although hemangioma is benign, it can destroy surrounding tissues and some of them show infiltrative growth, thus causing cosmetic defects in children. In addition it can also lead to functional impairment. In rare cases, hemangiomas are characterized by a malignant process and can have numerous complications such as ulceration, bleeding, infection, etc., which can even endanger the life of the child. The diagnosis of pediatric hemangiomas is generally not difficult, but their treatment is still not fully resolved, especially for large cavernous hemangiomas and arterial hemangiomas, which are still a major medical problem. Most patients are seen late, and it is precisely the timing of starting treatment that is decisive for prognosis. About 2/3 of hemangiomas are detected after birth, so the right time to start treatment is from the neonatal period.
