Procedural pediatric dermatology: From liquid nitrogen to laser, surgery, and multimodal skin care
The first generation of pediatric dermatologists were considered medical dermatologist specialists. The care of the conditions discussed above, as well as genodermatoses, diagnostic dilemmas, and management of dermatologic manifestations of systemic disease and other conditions, was the “bread and butter” of pediatric dermatology care. When I was in training, my mentor Paul Honig, MD, at the Children’s Hospital of Philadelphia had a procedure half-day each week, where he would care for a few patients who needed liquid nitrogen therapy for warts, or who needed biopsies. It was uncommon to have a large procedural/surgical part of pediatric dermatology practice. But this is now a routine part of many specialists in the field. How did this change occur?

The fundamental shift began to occur with the introduction of the pulsed dye laser for treatment of port-wine birthmarks in children with minimal scarring, and a seminal article published in the New England Journal of Medicine in 1989. Vascular lesions including port-wine stains were common, and pediatric dermatologists managed these patients for both diagnosis and medical management. Also, dermatology residencies at this time offered training in cutaneous surgery, excisions (including Mohs surgery) and repairs, and trainees in pediatric dermatology were “trained up” to high levels of expertise. As lasers were incorporated into dermatology residency work and practices, pediatric dermatologists developed the exposure and skill to do this work. An added advantage was having the knowledge of how to handle children and adolescents in an age-appropriate manner, with consideration of methods to minimize the pain and anxiety of procedures. Within a few years, pediatric dermatologists were at the forefront of the use of topical anesthetics (EMLA and liposomal lidocaine) and had general anesthesia privileges for laser and excisional surgery.
So while pediatric dermatologists still do “small procedures” every hour in most practices (cryotherapy for warts, cantharidin for molluscum, shave and punch biopsies), a subset now have extensive procedural practices, which in recent years has extended to pigment lesion lasers (to treat nevus of Ota, for example), hair laser, and combinations of lasers, including fractionated CO2 technology, to treat hypertrophic, constrictive and/or deforming scars.
The future
What will pediatric dermatology be like in 10, 20, or 50 years?
I have not yet discussed some of the most challenging diseases in our field, including epidermolysis bullosa, ichthyosis, and neurocutaneous disorders and other genetic skin disorders that have an incredible impact on the lives of affected children and their families, with incredible morbidity and with many conditions that shorten lifespans. But these are the conditions where “the future is happening now,” and we are looking forward to our new gene therapy techniques helping to transform our care.
And other aspects of practice? Will we be doing a large percentage of practice over the phone (or whatever devices we have then – remember, the first iPhone was only released 13 years ago)?
Will our patients be using their own imaging systems to evaluate their nevi and skin growths, and perhaps to diagnose and manage their rashes?
Will we have prevented our inflammatory skin disorders, or “turned them off” in early life with aggressive therapy in infantile life?
I project only that all of us in dermatology will still be a resource to our pediatric patients, from neonate through young adult, through our work of preventing, caring, healing and minimizing disease impact, and hopefully enjoying the pleasures of seeing our patients healthfully develop and evolve! As will our field.
