Port-Wine Stain Nodules in the Adult: Report of 20 Cases Treated by CO2 Laser Vaporization

DERMATOLOGIC SURGERY, Issue 8 2001
Jesús Del Pozo MD
Background. Port-wine stain (PWS) is a congenital vascular malformation of the superficial dermal vessels. These vessels become progressively ectatic, with development of nodular and hypertrophic areas on the surface of the lesions. Objective. To determine the efficacy of CO2 laser vaporization in the treatment of nodules in PWS. Methods. Twenty adult patients with PWS who developed nodules and hypertrophy on the surface of the lesions were treated by CO2 laser vaporization. Only one pass was performed to each area of the lesions, using a continuous and defocused mode, with a power density of 10 W/cm2. When the treated lesion was very large, several sessions of treatment were necessary to vaporize its entire surface. Photographic controls were performed before and after treatment. Results. The nodules and hypertrophy were removed and the smooth surface of the lesions was reestablished. The color, usually violaceous, was transformed in a slight erythema. Conclusion. CO2 laser is a good method for treatment of nodules and hypertrophy in PWS. With adequate precautions, excellent cosmetic results can be obtained. Other more-specific laser systems may be successively used to treat the remaining erythema. [source]

Ocular Complication of PhotoDerm VL Therapy for Facial Port-Wine Stain

Treatment of Port-Wine Stain Birthmarks Using the 1.5-msec Pulsed Dye Laser at High Fluences in Conjunction with Cryogen Spray Cooling

DERMATOLOGIC SURGERY, Issue 4 2002
Kristen M. Kelly MD
Background. The majority of port-wine stain (PWS) patients treated with the pulsed dye laser (PDL) do not achieve complete blanching. Safe administration of higher fluences has been proposed as a means of improving treatment efficacy. Objective. To determine the safety and efficacy of PWS treatment with the 1.5-msec PDL at high fluences in conjunction with cryogen spray cooling. Methods. Twenty PWS patients were treated with the PDL in combination with cryogen spray cooling utilizing a 7 or 10 mm spot size and fluences ranging from 6 to 15 J/cm2. Before and after treatment photographs were compared on a blinded basis. Results. No scarring or skin textural changes occurred. Blanching scores were as follows: 20% of patients achieved 75% or greater blanching after an average of 3.3 treatments, 30% achieved 50,74% blanching, 20% achieved 25,49% blanching, and 30% achieved less than 25% blanching. Conclusion. In conjunction with cryogen spray cooling, the PDL can be safely used at high fluences. At this time it is not clear that the use of higher fluences improves treatment efficacy; however, as other aspects of PWS laser treatment are optimized, safe administration of higher fluences is likely to be advantageous.

Thorium X treatment: multiple basal cell carcinomas within a port-wine stain

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 5 2009
J. Natkunarajah
Summary Thorium X is an ionizing radiation treatment that was commonly used by dermatologists in the 1930 s to 1950 s to treat a variety of benign dermatoses and vascular lesions including port-wine stains. By the 1960 s, thorium X was discontinued due to poor clinical results and the carcinogenic potential. We report a 64-year-old man with a history of multiple basal cell carcinomas in a facial port wine stain, which had previously been treated with thorium X. [source]

Folliculosebaceous cystic hamartoma arising within a port-wine stain

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 5 2005
C.-H. Yang
Summary A 34-year-old woman presented with 2-year history of a dome-shaped papule on a well-circumscribed, thickened, port-wine stain on the left side of the chin. Squeezing on the port-wine-stain plaque revealed many comedos within dilated follicular orifices. The papule was excised and submitted for histological examination. Histopathological study showed a lobular neoplasm, comprising dilated, cystic pilosebaceous structures surrounded by fibrous stroma, bearing the characteristics of folliculosebaceous cystic hamartoma. The reported case shows that, in addition to the vascular nature, both ectodermal and mesenchymal abnormalities may be involved in port-wine stains. [source]

Hemangiomas: Evaluation and Treatment

DERMATOLOGIC SURGERY, Issue 5 2001
Scott M. Dinehart MD
Background. Hemangiomas are common skin tumors of infancy that have undergone recent changes in nomenclature, methods of evaluation, and treatment. Objective. To review the nomenclature, epidemiology, evaluation, and treatment of common hemangiomas. Methods. A literature search was conducted utilizing MEDLINE and the Cochrane library databases. Text search words used were "hemangioma" and "infancy." The clinical experience of the authors was also used to formulate the review. Results. There have been many advances in nomenclature and therapeutic options for children with hemangiomas. Hemangiomas are proliferative tumors of infancy that should be distinguished from structural malformations, such as port-wine stains and lymphangiomas. Conclusion. Natural involution remains a viable treatment option for the majority of patients with uncomplicated hemangiomas. Excisional surgery, laser, and pharmacologic remedies are indicated for a subset of complicated hemangioma patients. [source]

IPL technology: A review

LASERS IN SURGERY AND MEDICINE, Issue 2 2003
Christian Raulin MD
Abstract Background and Objectives Intense pulsed light (IPL) systems are high-intensity light sources, which emit polychromatic light. Unlike laser systems, these flashlamps work with noncoherent light in a broad wavelength spectrum of 515,1,200 nm. These properties allow for great variability in selecting individual treatment parameters and adapting to different types of skin types and indications. The purpose of this article was to critically review international medical publications of the many indication in which IPL technology can be used, including our own evaluations and experiences. Study Design/Materials and Methods The range of therapeutic uses for high-intensity flashlamps was reviewed, ranging from benign cavernous hemangiomas, benign venous malformations, essential telangiectasias, leg telangiectasias, poikiloderma of Civatte, and port-wine stains to pigmented lesions, cosmetically undesired hypertrichosis, and facial rhydids. The relative benefits and risks were discussed in detail and compared with other laser systems. Results Because of the wide spectrum of potential combinations of wavelengths, pulse durations, pulse frequency, and fluences, a great deal of experience is required when using IPL technology. Proper patient selection and critical diagnostics serve to keep the adverse effects of the treatment to a minimum. Conclusions The distinctive technical conditions involved combine to make IPL technology an alternative and auxiliary treatment option to existing laser systems and conventional therapies.

Introduction of the flash-lamp pulsed-dye laser treatment of facial port-wine stains in childhood: A case of health care technology assessment

LASERS IN SURGERY AND MEDICINE, Issue 2 2001
C.A.J.M. De Borgie MSc
Abstract Background and Objective Lasers have been used in the treatment of port-wine stains (PWS) for more than 30 years. With the introduction of the flash-lamp pulsed-dye laser (FPDL) it was assumed that infants could be treated safely, effectively, and probably more efficiently. Nowadays, FPDL treatment is an established form of treatment of PWS in childhood. Study Design/Materials and Methods On the basis of the iterative Health Care Technology Assessment (HCTA) loop, we examined whether sufficient evidence from evaluations has been present to support the introduction of FPDL treatment for facial PWS at an early age. Such an assessment requires an interdisciplinary approach focusing on aspects of safety, efficacy, effectiveness, quality of life, costs, and the ethical issues of treatment. Results Assessment of the FPDL in PWS treatment of children did not follow the model of medical innovation and evaluation. Most assessments have been focused on laser applications that were already in clinical use. Efficacy and effectiveness of laser treatment have been the major concern in most assessments. Only a few studies have looked at costs and ethical aspects of treating children. Conclusions The introduction and diffusion of the use of the FPDL in the treatment of PWS in childhood were uncontrolled, and the field was not prepared to use this technique properly. We believe that this nonadherence to the iterative HCTA model reflects the gradual way by which innovations find their way into clinical practice. Lasers Surg.

Pulsed dye laser vs. intense pulsed light for port-wine stains: a randomized side-by-side trial with blinded response evaluation

BRITISH JOURNAL OF DERMATOLOGY, Issue 2 2009
A. Faurschou
Summary Background, Pulsed dye lasers (PDLs) are considered the treatment of choice for port-wine stains (PWS). Studies have suggested broadband intense pulsed light (IPL) to be efficient as well. So far, no studies have directly compared the PDL with IPL in a randomized clinical trial. Objectives, To compare efficacy and adverse events of PDL and IPL in an intraindividual randomized clinical trial. Methods, Twenty patients with PWS (face, trunk, extremities; pink, red and purple colours; skin types I,III) received one side-by-side treatment with PDL (V-beam Perfecta, 595 nm, 0·45,1·5 ms; Candela Laser Corporation, Wayland, MA, U.S.A.) and IPL (StarLux, Lux G prototype handpiece, 500,670 and 870,1400 nm, 5,10 ms; Palomar Medical Technologies, Burlington, MA, U.S.A.). Settings depended on the preoperative lesional colour. Treatment outcome was evaluated by blinded, clinical evaluations and by skin reflectance measurements. Results, Both PDL and IPL lightened PWS. Median clinical improvements were significantly better for PDL (65%) than IPL (30%) (P = 0·0004). A higher proportion of patients obtained good or excellent clearance rates with the PDL (75%) compared with IPL (30%) (P = 0·0104). Skin reflectance also documented better results after PDL (33% lightening) than IPL (12% lightening) (P = 0·002). Eighteen of 20 patients preferred to receive continued treatments with PDL (P = 0·0004). No adverse events were observed with PDL or IPL. Conclusions, Both the specific PDL and IPL types of equipment used in this study lightened PWS and both were safe with no adverse events. However, the PDL conveyed the advantages of better efficacy and higher patient preference. [source]
