Current Practices in Pediatric Dermatology Laser Therapy: An International Survey.

BACKGROUND AND OBJECTIVES: To date, there are no well-established guidelines regarding laser therapy for the treatment of cutaneous lesions in pediatric patients. We aim to ascertain the types of lasers commonly used, types of lesions treated, and factors that affect the selection of specific laser modalities in pediatric patients. STUDY DESIGN/MATERIALS AND METHODS: An anonymous online survey was distributed to healthcare providers who treat children with lasers through listservs of four major national and international dermatology and laser organizations. RESULTS: Outpatient office-based procedure rooms are the most common clinical setting for laser procedures (74.4%), and pulsed dye laser is the most commonly used laser (95.4%). Conditions routinely treated with lasers included port wine stains (95.4%), infantile hemangiomas (81.5%), other vascular lesions (81.5%), scars (77.7%), and hair (60.8%). 84.4% of respondents expressed concern about general anesthesia in patients <2 years old. Nevi of Ota is treated with laser more frequently (52.3%) than other pigmented lesions. LIMITATIONS: Limited generalizability of case examples to general conditions. CONCLUSIONS: Vascular lesions are the most common lesions treated with lasers in pediatric dermatology patients, and most providers are using these devices in the outpatient setting. Many providers are concerned about the effects of repeated general anesthesia in infants, and there appears to be a trend toward providing laser therapy in the outpatient setting without general anesthesia.

Evolution of congenital melanocytic nevi toward benignity: A case series.

We report on four children born with medium to large congenital melanocytic nevi (CMN) with color heterogeneity and irregular surface rugosity. As these patients aged, their nevi evolved to become more homogeneous and lighter in color, and developed a smoother, more even texture. We propose that given this evolution toward benignity, conservative monitoring and management may be appropriate even in the context of atypical-appearing features at birth. Such knowledge regarding the evolution of these CMN can more accurately guide parents and clinicians in determining whether to biopsy or remove an atypical-looking lesion early in life for medical or cosmetic reasons.

Keratosis pilaris rubra: a common but underrecognized condition.

BACKGROUND: Keratosis pilaris is a common skin disorder of childhood that often improves with age. Less common variants of keratosis pilaris include keratosis pilaris atrophicans and atrophodermia vermiculata. OBSERVATIONS: In this case series from dermatology practices in the United States, Canada, Israel, and Australia, the clinical characteristics of 27 patients with keratosis pilaris rubra are described. Marked erythema with follicular prominence was noted in all patients, most commonly affecting the lateral aspects of the cheeks and the proximal arms and legs, with both more marked erythema and widespread extent of disease than in keratosis pilaris. The mean age at onset was 5 years (range, birth to 12 years). Sixty-three percent of patients were male. No patients had atrophy or scarring from their lesions. Various treatments were used, with minimal or no improvement in most cases. CONCLUSIONS: Keratosis pilaris rubra is a variant of keratosis pilaris, with more prominent erythema and with more widespread areas of skin involvement in some cases, but without the atrophy or hyperpigmentation noted in certain keratosis pilaris variants. It seems to be a relatively common but uncommonly reported condition.
