Capillary hemangioma is a common skin disorder, mostly occurring on the face, head and neck, trunk and limbs. Strawberry hemangioma is most commonly seen in infants and young children. It is a pinpoint-sized red dot on the skin a few days after birth and is not easily noticed by parents. Many parents also mistake it as “birthmark” and let it develop, while others may be told that hemangioma does not need treatment and can be cured by itself. In some cases, the capillaries are dilated and enlarged and rapidly extend into the dermis and subcutaneous tissues, resulting in disability and malformation. Most of the clinical routine take freezing, laser and other methods or surgical excision, more or less with varying degrees of pain, adults can still tolerate, for young children is much less acceptable, and easy to leave a scar. In fact, in addition to these traditional methods, radioisotope dressing treatment is a better treatment method. The radioactive isotope dressing treatment is the use of nuclide hair body beta rays, so that the local lesions produce radiation biological effect and achieve the purpose of treatment, no effect on the surrounding normal tissue and the whole body, generally no scar after healing, there are two types of dressing device commonly used, one is the nuclide manufacturer to provide commercial dressing device, a metal product, a certain shape and size, mostly using radionuclide strontium-90. According to the shape of the lesion under the premise of protecting the normal skin around the direct dressing, treatment can be used once a large dose method or multiple small dose method; the other is by the use of the unit temporarily prepared into a dressing tablets, mostly choose radionuclide phosphorus-32, usually phosphorus-32 bath preparation to a certain concentration of radioactivity, with high-quality filter paper as a support and then according to the various shapes of the lesion into the corresponding size of the dressing device, directly It is applied directly to the lesion, and the time of application is decided according to the age and condition. The earlier the treatment, the better, and the younger the age, the better. The second treatment is usually done after an interval of 3-5 months. Both methods have good efficacy on pediatric cutaneous hemangioma. According to statistics, the efficiency of treatment for simple hemangioma and bright red nevus is 98.3% and 88.2% respectively. Isotope dressing treatment features: thorough treatment, no scar, simple, economical, painless and itch-free method, especially adapted to the treatment of children’s cutaneous hemangioma.
