ABSTRACT
BACKGROUND: Pediatric melanoma presents with distinct clinical features compared to adult disease. OBJECTIVE: Characterize risk factors and negative outcomes in pediatric melanoma. METHODS: Multicenter retrospective study of patients under 20 years diagnosed with melanoma between January 1, 1995 and June 30, 2015 from 11 academic medical centers. RESULTS: Melanoma was diagnosed in 317 patients, 73% of whom were diagnosed in adolescence (age ≥11). Spitzoid (31%) and superficial spreading (26%) subtypes were most common and 11% of cases arose from congenital nevi. Sentinel lymph node biopsy was performed in 68% of cases and positive in 46%. Fatality was observed in 7% of cases. Adolescent patients with melanoma were more likely to have family history of melanoma (P = .046) compared to controls. LIMITATIONS: Retrospective nature, cohort size, control selection, and potential referral bias. CONCLUSION: Pediatric melanoma has diverse clinical presentations. Better understanding of these cases and outcomes may facilitate improved risk stratification of pediatric melanoma.

OBJECTIVE: To describe the clinical and laboratory outcomes of infants with subcutaneous fat necrosis of the newborn (SCFN) and propose a care algorithm. METHODS: This single-center, retrospective study of infants diagnosed with SCFN at Ann & Robert H. Lurie Children's Hospital of Chicago from 2009 to 2019. RESULTS: Of 32 infants who met inclusion criteria, most were born full-term (84%), born via cesarean section (58%), had normal weight for gestational age (69%), and experienced delivery complications (53%). Twenty-nine infants (91%) had calcium drawn, and all had hypercalcemia. Three infants developed clinical symptoms of hypercalcemia, two required hospital admission, two developed nephrocalcinosis, and one developed acute kidney injury. The majority of infants (62%) had a peak ionized calcium between 1.5 and 1.6 mmol/L. No infants with peak ionized calcium less than 1.5 mmol/L developed complications of hypercalcemia. Most patients were diagnosed with hypercalcemia (86%) and demonstrated peak ionized calcium levels (59%) within the first 28 days of life. No patients developed hypercalcemia after 3 months of age. CONCLUSION: Hypercalcemia occurred in 100% of infants who had laboratory monitoring. We recommend obtaining an initial ionized calcium level when SCFN is suspected, and monitoring for the first 3 months of life if hypercalcemia has not been detected. In patients with asymptomatic hypercalcemia less than 1.5 mmol/L, there appears to be low likelihood of related complications. For symptomatic, markedly elevated (>1.6 mmol/L), or persistently elevated levels (>6 months) we suggest coordinated care with endocrinology or nephrology, consider hospitalization, and urinary system ultrasound.

BACKGROUND/OBJECTIVES: The principal environmental risk factor for conventional nevi and melanomas is ultraviolet exposure. However, little is known about genetic or environmental risk factors for developing Spitz tumors. This study investigates risk factors associated with Spitz neoplasms. METHODS: Patients with Spitz tumors seen at Northwestern Memorial Hospital and Lurie Children's Hospital were surveyed with a 16-item questionnaire about environmental and inherited factors. Spitz tumor patients were compared to a pediatric control cohort from a similar clinical setting. This was supplemented with a meta-analysis of genetic and environmental causes of Spitz neoplasms. RESULTS: One hundred and six Spitz and 58 control surveys were obtained and no statistically significant differences in genetic or environmental risk factors were found between Spitz and control groups. CONCLUSION: Our data and meta-analysis suggest that typical risk factors associated with melanoma are not significantly associated with Spitz tumors. Identification of relevant genetic or environmental risk factors will likely require larger and population-based studies.

Retrospective chart review was conducted to identify the clinical features of Henoch Schonlein purpura (HSP) in five children with inflammatory bowel disease (IBD). All five children, four of which were on anti-TNF therapies, experienced the onset of HSP after their IBD diagnosis. HSP averaged 20.8 months in duration. The patients in our cohort, particularly those on anti-TNF therapy for inflammatory bowel disease, experienced chronic and recurrent courses of HSP.

BACKGROUND: Pediatric melanoma is rare and diagnostically challenging. OBJECTIVE: To characterize clinical and histopathologic features of fatal pediatric melanomas. METHODS: Multicenter retrospective study of fatal melanoma cases in patients younger than 20 years diagnosed between 1994 and 2017. RESULTS: Of 38 cases of fatal pediatric melanoma identified, 57% presented in white patients and 19% in Hispanic patients. The average age at diagnosis was 12.7 years (range, 0.0-19.9 y), and the average age at death was 15.6 years (range, 1.2-26.2 y). Among cases with known identifiable subtypes, 50% were nodular (8/16), 31% were superficial spreading (5/16), and 19% were spitzoid melanoma (3/16). One fourth (10/38) of melanomas arose in association with congenital melanocytic nevi. LIMITATIONS: Retrospective nature, cohort size, and potential referral bias. CONCLUSIONS: Pediatric melanoma can be fatal in diverse clinical presentations, including a striking prevalence of Hispanic patients compared to adult disease, and with a range of clinical subtypes, although no fatal cases of spitzoid melanoma were diagnosed during childhood.

OBJECTIVE: To characterize the risk for ocular complications in patients with PHACE syndrome. STUDY DESIGN: This study included consecutive patients with PHACE syndrome who were seen at Lurie Children's Hospital of Chicago from January 2000 through May 2017. A complete ophthalmic examination was performed in all patients, with extra attention for findings typically associated with PHACE syndrome. RESULTS: Thirty patients (67% female, median age of onset 0.08 months) were included: 38 (93%) demonstrated a segmental infantile hemangioma distribution. Twenty-one (70%) cases had a periocular involvement, and 47% had an infantile hemangioma with a deep component. Among 21 patients with periocular distribution, 9 had ocular complications secondary to the periocular location (mainly ptosis, nasolacrimal duct obstruction, and refractive errors), and one had an ocular complication specifically associated with PHACE syndrome (Horner syndrome). None of the patients without periocular distribution had an ocular complication. CONCLUSIONS: In patients with PHACE syndrome who have a periocular infantile hemangioma, a complete eye examination is recommended. Although specific ocular anomalies related to PHACE syndrome are rare, serious ocular complications secondary to the location of the hemangioma may be present. Eye examination in patients with PHACE syndrome without a periocular infantile hemangioma distribution is likely of low yield.

BACKGROUND/OBJECTIVES: Cutaneous juvenile xanthogranuloma is an uncommon, usually benign disease affecting infants and young children. Ocular and other systemic involvement have been reported, but their incidence is unclear, and the utility of routine screening is not well established. Our aim was to characterize the risk of ocular and systemic complications in children with cutaneous juvenile xanthogranuloma. METHODS: In this retrospective study, we reviewed the medical charts of children with cutaneous juvenile xanthogranuloma seen at Ann and Robert H. Lurie Children's Hospital, Chicago, Illinois, between January 2000 and December 2015. A comprehensive literature review was also performed. RESULTS: Of 338 children with cutaneous juvenile xanthogranuloma, 76 (median age 6 months, 51% female) met inclusion criteria. The most frequently involved site was the head and neck region (40%). In 39 patients (51%), there was a single lesion. Multiple lesions (>5) were evident in 20 patients (26%). Most cutaneous juvenile xanthogranulomas were micronodular (77%). None of the patients had ocular involvement. One patient had multiple asymptomatic hepatic nodules on imaging that regressed spontaneously within several months. Literature review of pediatric cutaneous juvenile xanthogranuloma series, including our cohort, revealed that the incidence of ocular manifestations is 0.24% (7/2949) and of systemic manifestations is 0.75% (22/2949). CONCLUSION: Cutaneous juvenile xanthogranulomas are generally limited to the skin. Because eye involvement is rare, a routine eye examination is of low yield and probably not warranted in children with no ocular or visual symptoms. New recommendations for systemic screening could not be drawn from this study.

OBJECTIVES: Erythema annulare centrifugum (EAC) is an uncommon eruption that may be a hypersensitivity reaction. Treatment of EAC is best accomplished by eliminating the underlying cause. Although many triggers have been reported, the inciting factor is unknown in most patients. We hypothesized that occult yeast overgrowth may trigger EAC in patients with EAC of unknown etiology. METHODS: Five children with EAC were treated empirically with oral fluconazole. These cases were retrospectively reviewed. RESULTS: Improvement was noted in all patients; three cleared entirely. Two patients experienced recurrences after successful treatment, which were treated with a second course of fluconazole. The treatment was well tolerated, without adverse effects. CONCLUSION: Oral fluconazole was an effective treatment in five children with EAC.

Atopic dermatitis (AD) is extremely common in the pediatric population, and most children with AD will first present to their primary care provider (PCP). The PCP can recognize AD by its clinical features, including itch, a chronic relapsing course, and the characteristic eruption. The cornerstone of AD therapy is dry skin care, typically a short daily bath/shower followed by an emollient applied to all skin. Most children with AD will also require topical medications, such as topical corticosteroids and/or topical nonsteroidal therapies. For children with more severe disease, systemic agents, including several novel therapies, may be required. In managing AD, the clinician must monitor for side effects of medications as well as complications of the AD itself, the most common of which is secondary infection. An understanding of the pathogenesis, treatments, and complications of AD is essential for the PCP, as untreated (or undertreated) AD has a significant impact on the quality of life of affected children and their caregivers.

We describe the first cases of pediatric melanoma with ALK fusion gene arising within giant congenital melanocytic nevi. Two newborn boys presented with large pigmented nodular plaques and numerous smaller satellite nevi. Additional expansile nodules developed within both nevi and invasive melanomas were diagnosed before 10 months of age in both boys. Oncogenic driver mutations in NRAS and BRAF were absent in both cases. Instead, oncogenic ZEB2::ALK fusion genes were identified in both the nevus and melanoma developing within the nevus. In both cases, tumors were noted by ultrasound in utero, demonstrated significant nodularity at birth, and progressed to melanoma in the first year of life suggesting that congenital nevi with ALK fusion genes may behave more aggressively than those with other mutations. As ALK kinase inhibitors are effective against a range of tumors with similar ALK fusion kinases, identifying ALK fusion genes in congenital melanocytic nevi may provide an opportunity for targeted therapy.

A 3-year-old girl presented with a linear eruption on her leg for 2 months. She was otherwise healthy and well-appearing. Physical examination showed many small, erythematous, flat-topped papules coalescing into a linear erythematous plaque. At a follow-up visit 9 months later, the eruption had resolved, leaving postinflammatory hypopigmentation.When approaching a cutaneous eruption, appreciating the pattern of the lesions can be instrumental to arriving at the correct diagnosis. For this patient with the acute onset of a plaque on the leg, the differential diagnosis is narrowed by the linear distribution of the skin lesions. The differential diagnosis of linear eruptions in children includes lichen striatus, linear lichen planus, linear psoriasis, inflammatory linear verrucous epidermal nevus, incontinentia pigmenti, phytophotodermatitis, and allergic contact dermatitis. Of note, many of these conditions manifest in a linear manner as a result of cutaneous mosaicism, whereas others are caused by external agents contacting the skin.
