Agminated Eruptive Melanocytic Nevi and Nail Changes Following Toxic Epidermal Necrolysis in a Pediatric Patient: A Case Report and Systematic Review of the Literature.

Eruptive melanocytic nevi (EMN) have been reported in the setting of immunosuppression, chemotherapy, and bullous skin disease, including less commonly, Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). This case report presents a 4-year-old girl who developed agminated EMN and nail changes after TEN. A systematic review of the literature supports clinically appropriate follow-up of EMN, as there is no reports of malignancy in EMN following SJS/TEN, nor reports of pediatric melanoma arising within EMN of any etiology. Further study of the possible correlation of nail changes with the development of EMN and better characterization of the dermoscopic features of EMN could improve monitoring and care of these patients.

Corymbiform cutaneous disorders in pediatric dermatology: Exploring this pattern of presentation beyond secondary syphilis.

"Corymbiform" is a term found in medical literature as early as 1876 to describe a central larger lesion with smaller surrounding lesions, leading to the appearance of an irregular border. While the term in current medical literature most often describes a possible morphology of secondary syphilis, the authors have noted this pattern presenting in other cutaneous conditions. We present a commentary on the corymbiform pattern in dermatology including a series of photographs of cutaneous disorders presenting in a corymbiform morphology in pediatric patients. While the term corymbiform is not commonly used in the present-day dermatologic literature, increased recognition and use of this term may aid in the recognition of various dermatologic diagnoses presenting in a less common morphology and may also lend to increased fluidity of dermatologic descriptions in the literature.

Granuloma Annulare-Like Id Reaction to Inflamed Molluscum Contagiosum: A Case Report.

Molluscum contagiosum (MC) is a viral cutaneous infection common in children. It is characterized by umbilicated, skin-colored papules that typically resolve without treatment over several months to years. Immune response to the virus may cause inflammatory reactions, including molluscum dermatitis, inflamed molluscum, Gianotti-Crosti syndrome-like reaction, erythema annulare centrifugum, or even a generalized id reaction (a reactive inflammatory process driven by a separate condition that stimulates the immune system). We report a unique case of a granuloma annulare-like id reaction secondary to immune recognition of MC in a pediatric patient followed by rapid resolution of their MC.

Repurposing of antiangiogenic agents for treatment of vascular anomalies.

Vascular anomalies (VA) are developmental anomalies of veins, arteries, lymphatics or capillaries thought to be caused by mutations in genes that drive angiogenesis. Treatments targeting these genes are limited. We review the literature for conventional medications and products from traditional medicine cultures that have been found to have antiangiogenic activity. Fewer than 50 drugs with credible human activity in VA were identified and include ß blockers, monoclonal antibodies, microtubule inhibitors, multi-kinase inhibitors, PIK3CA- and RAS-MAPK pathway inhibitors, and thalidomides. Other drug categories of potential interest are ACE-inhibitors, antifungals, antimalarials, MMP9-inhibitors, and over-the-counter compounds used in Eastern traditional medicine. Low toxicity for some offers the possibility of combined use with known effective agents. In addition to already familiar drugs, others with antiangiogenic capabilities already in use in children or adults may deserve further attention for repurposing for VA.

Update on lasers in pediatric dermatology: how primary care providers can help patients and families navigate appropriate treatment options and timelines.

PURPOSE OF REVIEW: The use of lasers in pediatric dermatology is well established, but recent literature has expanded the evidence for specific timelines of treatment. Additionally, new devices and combinations with medical therapy have improved outcomes and treatment options for various conditions. RECENT FINDINGS: Pulsed dye laser remains the first-line laser for vascular lesions. Recent guidelines support early initiation of laser treatment in port-wine birthmarks to optimize outcomes. For hemangiomas, laser treatment can offer a meaningful addition to oral propranolol therapy. Lasers with shorter wavelengths offer improved outcomes with decreased downtime for pigmented lesions. General anesthesia in the pediatric population continues to be a controversial topic, and the decision to perform laser under general versus topical anesthesia requires discussion with family of risks and benefits. SUMMARY: Primary care providers can benefit their patients by prompt referral to dermatology for discussion of laser treatment. Port-wine birthmarks require referral in the first weeks of life so that laser treatment can be initiated if appropriate. Although many dermatologic conditions cannot be completely cleared or cured with laser, treatment can offer meaningful outcomes and benefit for patients and families.
