This report documents the successful treatment of a hemangioma (strawberry hemangioma) at 5 weeks of age with the argon laser. The natural course of strawberry hemangioma of infancy is well known. It begins as a very small spot and develops very rapidly within the first few weeks of life. Many grow to a very large size and produce significant morbidity. It is logical to assume that if these were ablated early, the life cycle could be aborted. The patient of this case study developed two spots that appeared to be typical evolving hemangiomas. One was treated and disappeared. The other was not treated and evolved into a typical strawberry hemangioma that eventually involuted. This would indicate that early treatment holds some promise.  相似文献

The cosmetic concern associated with multiple trichoepitheliomas is obvious. Previous modes of therapy have proven to be only temporary. However, multiple trichoepitheliomas appear to respond to the thermocoagulation and epidermal atrophic effects of the argon laser without recurrence over an extended follow-up period. Although these lesions are not as highly vascular as port-wine hemangiomas, their dramatic response to the argon laser is similar. This report documents a case of multiple trichoepitheliomas treated successfully with the argon laser from the face and scalp of a 29-year-old white woman. The benefits of the argon laser in treatment of multiple trichoepitheliomas include eradication of the lesions without apparent recurrence, restriction of spread of solitary trichoepithelioma into adjacent tumors, and prevention of obstruction of the periorbital region and auditory canal. The treatment may be accomplished as a simple outpatient procedure under local anesthesia with minimal pain or disability.  相似文献

Twenty-two patients with cutaneous vascular malformations were treated with an argon laser. Promising results were obtained in patients with port-wine stains, hemangiomas, telangiectasia and varicose veins. The argon laser shows promise as an effective clinical tool in the treatment of all such cutaneous vascular abnormalities. However, further study of clinical as well as laboratory data is necessary over a long period of time before this modality can be definitely recommended as the treatment of choice for vascular deformities of the skin.  相似文献

Ten female infants were referred for symptomatic hemangiomas in the anogenital area. (One had had steroid treatment prior to consultation.) The natural history of these lesions is well known. Virtually all will spontaneously involute over a period of years. However, the lesions reported were particularly troublesome because of repeated ulcerations and subsequent pain. Prior treatment had been local wound care with antibiotic ointment and Telfa-type dressings. After referral from a family practitioner or pediatrician, argon laser treatment was performed in an outpatient setting. Eight of the 10 patients were treated with local anesthesia, and 2 had general anesthesia. All lesions healed in 1 to 5 weeks. No patients referred during this period were excluded from this series. All who received treatment were included. All the lesions involuted following treatment. In our estimation, the final result is identical to what may be expected after spontaneous involution of an ulcerated or infected hemangioma. The major difference is that involution occurred in a few weeks in laser-treated patients rather than a period of months or years. Ulcerated hemangiomas of the anogenital area have significant morbidity that can be efficiently avoided with the use of argon laser therapy. Lesions of the anogenital area have a strong predilection for females.  相似文献

Capillary hemangioma of infancy (strawberry mark) is a self-limiting problem, and conservative treatment is recommended. These birthmarks can be associated with a great deal of morbidity. There is definitely a role for a palliative form of treatment without systemic complications or destruction of adjacent tissue. In a 6-year period, 55 patients received 57 Nd:YAG or argon laser treatments. Thirty patients received 31 argon treatments, and 25 patients received 26 Nd:YAG treatments; and 2 received first argon with subsequent Nd:YAG treatments. Although more dramatic successes were noted in the Nd:YAG laser, complications were more frequent and severe. Complications included delayed healing, postoperative bleeding, and some hypertrophic scarring. Complications were seen in 12 percent of all patients, 9 percent of these associated with the Nd:YAG laser.  相似文献

A review of the literature on the natural history of strawberry hemangiomas revealed over-whelming evidence of the satisfactory spontaneous involution of over 95 per cent of these lesions without the scarring and danger of other sequelae inherent in the various forms of treatment. In a study of 105 strawberry nevi observed for more than one year, 97 per cent of the lesions had either completely disappeared or were regressing satisfactorily.A cross-section study of 1,735 consecutively examined children in routine pediatric practice showed hemangiomas to be present in 10.1 per cent of all infants from birth to one year of age but that this incidence drops to 1.5 per cent in children over five years of age, confirming the fact of spontaneous involution.  相似文献

Hemangiomas are considered tumors originating in blood vessels and are classified as ectatic and hyperplastic. Controversy regarding active therapy occurs in the case of strawberry hemangiomas which are hyperplastic capillary hemangiomas. Although they may clear up spontaneously, on rare occasions they may predispose to grave sequelae. Port-wine stain hemangiomas should never be treated with x-ray or radium.  相似文献

The vascular dynamics of port-wine hemangioma have been studied in several ways in order to better understand blood flow factors. Utilizing a laser Doppler velocimeter, differential perfusion/blood flow was studied and contrasted to normal skin, compared to heat and cold challenges, and finally measured in relationship to argon laser treatment. Results indicate that port-wine hemangiomas do not necessarily have different perfusion than normal skin but respond less vigorously to heat challenges. Cooling showed no uniform response by port-wine hemangioma vessels, while injection with Xylocaine plus epinephrine resulted in a markedly decreased perfusion and vasoconstriction contrary to previously held theories. Argon laser treatment did not uniformly alter laser Doppler perfusion to a predictable degree. Laser Doppler velocimeter flow studies were not able to predict future good versus bad results of laser treatment.  相似文献

Laser treatment in carcinoma of the bronchus is essentially palliative and is suitable for only a few patients. Patients selected for laser treatment must have predominantly endobronchial growth with normal bronchial anatomy still identifiable and symptoms due to the obstruction or to haemoptysis. A total of 34 patients with carcinoma of the bronchus were treated with argon gas or neodynium yttrium aluminium garnet crystal lasers. Good palliation was obtained in just over half the cases of partial obstruction of the trachea or main bronchus, but best results were obtained in lesions of the trachea or main carina. Re-expansion of the collapsed lung was achieved in some cases but with considerable risk of pneumonia. Haemoptysis was controlled at least partly in several cases. Laser treatment has the advantage of having no toxicity or dose limit and may be used in cases of poor respiratory function. The procedure was better tolerated than radiotherapy or chemotherapy and its relatively lower cost may justify setting up laser units in major cities.  相似文献

The argon laser, which has been proven both useful and safe for port-wine stain therapy, interacts with the hemoglobin of the vessels. In a percentage of cases, this treatment is still inefficient, and there is a lack of correlation between these bad results and clinical or histologic criteria. Thermography, which explores the vascularization of the port-wine stain, leads us to consider port-wine stains from a physical point of view. This very simple test shows no correlation with the clinical parameters of port-wine stain but is closely related to the results obtained with laser therapy. It seems to be a good criterion to estimate the argon laser treatment prognosis.  相似文献

BACKGROUND: Cellular hemangioma is a common benign vascular neoplasm of infants and children. The lesion typically occurs within the superficial dermis, where it is recognized as a strawberry nevus. Occasionally, this neoplasm is situated within deep soft tissues of the head or neck, with a particular predilection for the parotid gland region. Fine needle aspiration cytology (FNAC) of cellular hemangioma involving the parotid gland has been reported previously, but never confirmed by cytologic findings alone. We report the first case of infantile cellular hemangioma with sufficient characteristic cytologic features to be diagnosed by FNAC. CASE: A 3-month-old male presented with a rapidly enlarging, sensitive, solid, supraparotid mass. Ultrasound and computed tomography were performed but were nondiagnostic. Subsequent FNAC of the mass demonstrated a highly cellular specimen composed predominantly of elongated spindled cells arranged in three-dimensional coils and arcades. Immunohistochemistry demonstrated the endothelial origin of the spindled cells and confirmed the diagnosis of cellular hemangioma. CONCLUSION: Deeply situated cellular hemangiomas may pose a difficult diagnostic challenge to the clinician as well as to the radiologist. The infantile variant of this tumor enlarges rapidly, simulating an aggressive malignant tumor, and is occasionally accompanied by substantial compressive symptoms. Radiographic presentation of the lesion may be that of a solid tumor mass, unlike most other hemangiomas. Precise cytologic diagnosis of infantile cellular hemangioma can be rendered on aspirated material and is crucial in planning conservative medical treatment.  相似文献

Lasers produce a coherent, focused, monochromatic, high-energy form of light. Because laser surgery is more versatile and precise and is freer of complications than conventional surgery it has become widely accepted in ophthalmology over the past 10 years. Applications range from routine procedures in the fundus to recent, more delicate interventions in the cornea. The argon laser is the most widely used to treat extrafoveal chorioretinal diseases such as age-related macular degeneration and diabetic retinopathy; it has also been used successfully to treat glaucoma by iridectomy or trabeculoplasty. The krypton red laser is the argon laser''s counterpart in the treatment of subfoveal and pigment-epithelium-related diseases. Posterior capsulotomy is the most widespread and successful intervention with the neodymium:yttrium-aluminum-garnet crystal laser; this laser is also used to cut vitreous traction bands and is increasingly used in iridectomy. Although the use of the excimer laser in corneal surgery is still largely investigational it has been shown to produce precise cuts in corneal layers for the correction of myopia or astigmatism. The variable-wavelength dye laser, capable of reaching a specific level in the retina or choroid, has offered exciting new developments, and it promises to soon be part of the ophthalmologist''s armamentarium in the treatment of eye disease.  相似文献

The effect of argon laser irradiation on the microvessels of the subcutaneous fat tissue of rabbit's ear placed into Clark's transparent chamber was studied. Capillaries and venules were found to be sensitive to argon laser irradiation; functional disturbances of microcirculation were most distinct. Following laser irradiation an active reconstruction of the microcirculatory bed with the redistribution of the blood stream took place along with destruction of the vascular wall and perivascular inflammation.  相似文献

The argon laser is now a well-established method of treating port-wine stains (PWS) in the face and neck areas. Satisfactory results are reported in 44 to 75 percent of cases, but criteria for that classification and the patients' perceptions of the result are seldom given. In the present paper, a sample of 58 patients was used to assess the patients' own perceptions of the degree of lightening and scarring. Three felt the results were excellent, 23 good, 18 fair, and 14 poor. The treatment was considered as unpleasant by 76 percent, and 55 percent of the patients asked for a new consultation. Scarring was noticed by 50 percent. The patients' perceptions of the results and physicians' rating were the same in 69 percent. The best results were obtained in older patients with small port-wine stains. Such lesions also can be treated surgically with good results.  相似文献
