BACKGROUND AND OBJECTIVES: Port wine stains are congenital low-flow vascular malformations of the skin. Unlike hemangiomas, PWS do not involute with time, but rather if left untreated can hypertrophy and develop nodularity. Laser therapy of PWS particularly with pulsed-dye lasers, is a safe, well-established treatment that is successful in the majority of patients, especially for younger patients. Patients that fail to receive treatment early in life may subsequent develop lesions more likely to progress. STUDY DESIGN/PATIENTS AND METHODS: A case report and review of the literature are presented. We report a 43 year-old man born with a port-wine stain on the right side of his face that extended in the V2 distribution on his face. He had undergone several sessions with a pulsed-dye laser, the sequential dual-wavelength (595 nm and 1064 nm) laser and a CO2 resurfacing laser from the age of 26 but failed to follow through with a sufficient number of treatments to prevent hypertrophy. RESULTS: Due to an insufficient number and interval of treatments (with only 7 treatments over 16 years starting at age 26) with the various lasers, the patient's port wine stain continued to progress in color and development of nodularity. CONCLUSIONS: Patients born with port wine stains should have early laser treatment to achieve optimal results. Delay in treatment, as in this patient until age 26, may result in hard to treat PWS that can continue to progress in nodularity. This case illustrates the hypertrophy and nodularity that can occur due to progression of a PWS with failure to follow through with sufficient number of laser treatments

BACKGROUND AND OBJECTIVE: The effects of fractional resurfacing on eyelid tightening and aperture are unknown. Our purpose was to retrospectively examine the potential for eyelid tightening and eye-aperture opening in patients treated with nonablative fractional resurfacing for facial photorejuvenation. STUDY DESIGN/MATERIALS AND METHODS: Fractional laser treatments using a 1,550-nm erbium-doped fiber laser system on the upper and lower eyelids were given at a pulse energy of 17 to 20 mJ at 125 micro-thermal zones (MTZ)/cm(2) to a final density of 500 to 750 MTZ/cm(2). Each patient had 3 to 7 treatments. Standard pre- and post-treatment photographs were taken at each visit. Physicians who graded 31 preselected patient photographs using a 4-point scale evaluated eyelid tightening. Increase in eyelid aperture was also evaluated. RESULTS: All patients had some degree of eyelid tightening; 19% achieved 1% to 25% tightening, 26% achieved 25% to 50%, 26% achieved 50% to 75%, and 29% achieved 75% to 100%. Increase in eyelid aperture was seen in 55.9% of patients. Postoperative wounding, hypopigmentation, hyperpigmentation, persistent erythema, and scarring were not observed. All patients experienced mild or no edema for a few days after treatment. CONCLUSION: Fractional resurfacing tightens and increases eyelid aperture without wounding, downtime, or long-term complications

BACKGROUND: Improving the appearance of striae distensae, particularly striae alba, has remained a challenge due to the limited availability of effective and low-risk treatment options. Fractional photothermolysis, a novel concept in skin rejuvenation, has been reported to be effective in the treatment of facial rhytides, acne scars, and surgical scars, but its use in the treatment of striae has not been well studied. OBJECTIVE: To determine the safety and efficacy of fractional photothermolysis treatment on striae alba and striae rubra. METHODS: Twenty female patients with striae rubra or striae alba on their abdomen, thighs, or buttocks were enrolled in the study. Lesions were randomized to receive treatment, with site-matched normal control areas. Patients received a total of 6 treatments using a 1550-nm, erbium-doped fiber laser with 2 to 3 weeks of elapsed time between treatments. Clinical response to treatment was assessed at each visit, and at 1-month, 2-month, and 3-month follow-up intervals by the patient and investigator. A comparison evaluation of 8 patients examining photographs of striae at baseline and at the 3-month follow-up evaluation which was assessed by 4 independent dermatologists using the quartile grading scale. RESULTS: The independent evaluators' assessments of improvement from photographs of 8 randomly selected patients showed an overall improvement of 26% to 50% in 63% (5/8) of patients. A less than 25% improvement in dyschromia was noted in 50% (4/8) of patients. An improvement in texture of 26% to 50% was observed in 50% (4/8) of patients. The clinical responses were independent of age, gender, and skin phototype. The treatments were tolerated well by all patients with a majority of patients experiencing transient posttreatment erythema and edema. CONCLUSION: Fractional photothermolysis can be effectively and safely used in the treatment of striae rubra and striae alba
