ABSTRACT
OBJECTIVE: To develop consensus on diagnostic criteria for LUMBAR syndrome, the association of segmental infantile hemangiomas that affect the Lower body with Urogenital anomalies, Ulceration, spinal cord Malformations, Bony defects, Anorectal malformations, Arterial anomalies and/or Renal anomalies. STUDY DESIGN: These diagnostic criteria were developed by an expert multidisciplinary and multi-institutional team based on analysis of peer-reviewed data, followed by electronic-Delphi consensus of a panel of 61 international pediatric specialists. RESULTS: After 2 Delphi rounds, a 92% or higher level of agreement was reached for each Delphi statement. 98% of panelists agreed with the diagnostic criteria, and 100% agreed the criteria would be useful in clinical practice. The diagnosis of LUMBAR requires the presence of a segmental, or patterned, infantile hemangioma of the lumbosacral, sacrococcygeal, or pelvic cutaneous regions plus one additional criterion of the urogenital, spinal, bony, anorectal, arterial, or renal organ systems. CONCLUSIONS: These diagnostic criteria will enhance clinical care by improving screening, detection, and overall awareness of this poorly understood neurocutaneous disorder. The criteria can be utilized by a wide variety of pediatric subspecialists. In addition, formal criteria will improve phenotypic uniformity among LUMBAR syndrome cohorts and a patient registry, allowing investigators to assess clinical features, long-term outcomes, and results of genetic sequencing in a standardized manner. Finally, these criteria will serve as a starting point for prospective studies to establish formal screening and management guidelines.
ABSTRACT
OBJECTIVE: To characterize long-term outcomes of PHACE syndrome. STUDY DESIGN: Multicenter study with cross-sectional interviews and chart review of individuals with definite PHACE syndrome ≥10 years of age. Data from charts were collected across multiple PHACE-related topics. Data not available in charts were collected from patients directly. Likert scales were used to assess the impact of specific findings. Patient-Reported Outcomes Measurement Information System (PROMIS) scales were used to assess quality of life domains. RESULTS: A total of 104/153 (68%) individuals contacted participated in the study at a median of 14 years of age (range 10-77 years). There were infantile hemangioma (IH) residua in 94.1%. Approximately one-half had received laser treatment for residual IH, and the majority (89.5%) of participants were satisfied or very satisfied with the appearance. Neurocognitive manifestations were common including headaches/migraines (72.1%), participant-reported learning differences (45.1%), and need for individualized education plans (39.4%). Cerebrovascular arteriopathy was present in 91.3%, with progression identified in 20/68 (29.4%) of those with available follow-up imaging reports. Among these, 6/68 (8.8%) developed moyamoya vasculopathy or progressive stenoocclusion, leading to isolated circulation at or above the level of the circle of Willis. Despite the prevalence of cerebrovascular arteriopathy, the proportion of those with ischemic stroke was low (2/104; 1.9%). PROMIS global health scores were lower than population norms by at least 1 SD. CONCLUSIONS: PHACE syndrome is associated with long-term, mild to severe morbidities including IH residua, headaches, learning differences, and progressive arteriopathy. Primary and specialty follow-up care is critical for PHACE patients into adulthood.

Gorham-Stout disease (GSD) and generalized lymphatic anomaly (GLA) are subtypes of complex lymphatic malformations (CLMs) with osseous involvement that cause significant complications, including pain and pathologic fractures. As with other vascular anomalies, somatic mosaic mutations in oncogenes are often present, and the mTOR inhibitor sirolimus alleviates symptoms in some, but not all, patients. We describe two patients, one with GSD and one with GLA, found to have EML4::ALK fusions. This report of a targetable, oncogenic fusion in vascular malformations expands our understanding of the genetic basis for CLMs and suggests additional targeted therapies could be effective.
ABSTRACT
BACKGROUND: Capillary lymphatic venous malformations (CLVM) and associated syndromes, including Klippel-Trenaunay syndrome (KTS) and congenital lipomatous overgrowth, vascular malformation, epidermal nevi, skeletal, and spinal syndrome (CLOVES), are underrecognized disorders associated with high morbidity from chronic pain, recurrent infections, bleeding, and clotting complications. The rarity of these disorders and heterogeneity of clinical presentations make large-scale randomized clinical drug trials challenging. Identification of PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha [gene]) mutations in CLVM has made targeted medications, such as sirolimus, attractive treatment options. The aim of this study was to investigate the safety and efficacy of sirolimus therapy in CLVM. PROCEDURE: A combined prospective and retrospective cohort of pediatric and young adult patients with CLVM treated with sirolimus was evaluated for disease response, including symptom improvement, quality of life (QOL), and radiologic response. Sirolimus dosing regimens and toxicities were also assessed. RESULTS: Twenty-nine patients with CLVM, including KTS and CLOVES, were included. Ninety-three percent of patients reported improved QOL, and 86% had improvement in at least one symptom. Most significantly, improvement was noted in 100% of patients with bleeding and 89% with thrombotic complications with corresponding decreases in mean D-dimer (p = .008) and increases in mean fibrinogen (p = .016). No patients had progressive disease on sirolimus. Most common side effects included neutropenia, lymphopenia, infection, and aphthous ulcers/stomatitis. No toxicities were life-threatening, and none required long-term discontinuation of sirolimus. CONCLUSION: Sirolimus appears to be effective at reducing complications and improving QOL in patients with CLVM and associated syndromes. In this patient cohort, sirolimus was well tolerated and resulted in few treatment-related toxicities.

BACKGROUND: Ulceration is an important complication in infantile hemangiomas (IHs). Prior to the use of ß-blockers, the estimated incidence of this complication in a referral population was between 15% and 30%. The incidence and factors associated with ulceration have not been systematically studied since the emergence of ß-blocker therapy. OBJECTIVE: Examine the incidence and clinical predictors for ulceration in IHs. METHODS: Retrospective study at tertiary referral centers. RESULTS: Compared with a previous large pre-propranolol cohort study, ulceration occurred at a significantly lower incidence of 11.4%. Clinical factors associated with ulceration included partial segmental morphology, location in the diaper area, and size greater than 5 cm. Higher risk of ulceration in Black patients was observed, suggesting barriers to care including delayed diagnosis and referral to specialty care. LIMITATIONS: Retrospective design at tertiary referral centers. CONCLUSION: Compared with reports before the use of ß-blockers became widespread, the incidence of ulceration in IHs has decreased. However, it continues to be a relatively frequent complication of IH.

BACKGROUND: Infantile hemangiomas (IHs) of the anogenital region remain poorly characterized. OBJECTIVE: To examine the distribution, ulceration rate, and associated congenital anomalies of anogenital IHs. METHODS: Retrospective study at 8 tertiary referral centers. RESULTS: A total of 435 infants with an IH of the anogenital region were enrolled (of which, 319 [73%] were girls). Congenital anomalies were present in 6.4% (n = 28) of infants with an anogenital IH. Segmental or partial segmental anogenital IHs ulcerated in 72% (n = 99 of 138) of infants, whereas 45% (n = 133 of 297) of focal anogenital IHs experienced ulceration (P < .001). In a multivariable logistic regression analysis, segmental or partial segmental morphology (adjusted odds ratio [aOR], 2.70; 95% CI, 1.60-4.64), mixed type (aOR, 3.44; 95% CI, 2.01-6.07), and perianal (aOR, 3.01; 95% CI, 1.53-6.12) and buttocks location (aOR, 2.08; 95% CI, 1.17-3.76) had increased odds of ulceration. Segmental or partial segmental IHs of the genitalia were confined to distinct anatomic territories and were predominantly distributed unilaterally, with a linear demarcation at the perineal raphe. LIMITATIONS: Possible selection bias, given recruitment at tertiary referral centers. CONCLUSION: This study improves our understanding of high-risk features of anogenital IHs and demonstrates that genital segmental or partial segmental IHs develop within distinct anatomic territories.
ABSTRACT
BACKGROUND/OBJECTIVES: Early referral and treatment of infantile hemangioma (IH) is a major challenge for treatment success. However, there is a lack of data supporting a specific threshold for initiating treatment with oral propranolol. The aim of this analysis was to find factors, such as age at treatment initiation, leading to a higher success rate with oral propranolol treatment. METHODS: Based on data from the pivotal phase 2-3 clinical trial of oral propranolol in IH, we used Generalized Additive Model (GAM) charts with Generalized Linear Models (GLM), then a rule discovery algorithm, to identify sub-groups presenting a high probability of occurrence of the predefined outcome (i.e., success [complete or nearly complete resolution of the target hemangioma] at 6 months of treatment). RESULTS: Our analyses identified that patients who started oral propranolol 3 mg/kg/day before the age of 10 weeks had a success rate of 86%, higher than the 60% success rate for all patients that received the same regimen commencing after 10 weeks of age. CONCLUSIONS: Treatment initiation before 10 weeks of age was associated with a significantly higher rate of treatment success with oral propranolol 3 mg/kg/day. Infants with IH requiring treatment should be referred to an expert center and treated as soon as possible.

BACKGROUND/OBJECTIVES: We sought to describe the experience among members of the Hemangioma Investigator Group with pulsed dye laser (PDL) in the treatment of nonulcerated infantile hemangioma (IH) in pediatric patients in the pre- and post-beta-blocker era. METHODS: A multicenter retrospective cohort study was conducted in patients with nonulcerated IH treated with laser therapy. Patient demographics, IH characteristics, indications for/timing of laser therapy, as well as laser parameters were collected. Responses to laser therapy were evaluated using a visual analog scale (VAS). RESULTS: One hundred and seventeen patients with IH were treated with PDL. 18/117 (15.4%) had early intervention (defined as <12 months of life), and 99/117 (84.6%) had late intervention (≥12 months of life). In the late intervention group, 73.7% (73/99) had additional medical management of their IH. The mean age at PDL initiation for the late intervention group was 46.7 ± 35.3 months of life (range 12-172 months) with total number of treatments to maximal clearing of 4.2 ± 2.8 (range 1-17). Those who received propranolol prior to PDL received fewer sessions (1.1 fewer sessions, approaching significance [p = .056]). On the VAS, there was a mean 85% overall improvement compared to baseline (range 18%-100%), with most improvement noted in erythema and/or telangiectasias. The incidence of adverse effects was 6/99 (6.1%). CONCLUSIONS: PDL is a useful tool in the treatment of IH, with notable improvement of telangiectasia and erythema and low risk of complications. PDL is often introduced after the maximal proliferative phase.

BACKGROUND/OBJECTIVES: Ulceration is a common complication of infantile hemangioma (IH). Severe, persistent ulceration occurs in a minority of patients. This study aims to characterize the clinical features of IH with aggressive ulceration (AU). METHODS: Multicenter retrospective study of clinical features of IH with AU. RESULTS: Thirty-five patients with AU were identified and included in the study. The majority of AU occurred in segmental IH (23/35, 65%). Segmental IH with AU were large (≥10 cm2 ; 16/23, 69%, p < .001) with a thin (<3 mm) superficial component (16/23, 69%, p < .001). Localized IH with AU had a thick (>3 mm) superficial component (11/12, 92%, p < .001). All diaper area IH with AU (9/35) were segmental with thin superficial component (100%, p = .02). IH with AU in the head/neck (10/35) were more commonly localized (67%) and mixed (62.5%), while segmental, thick superficial morphology was more common on trunk (9/35) and upper extremities (7/35). CONCLUSIONS: IH resulting in AU differ in clinical features by anatomic site. Those in the diaper area are nearly always segmental with thin superficial component, whereas other sites tend to be localized, mixed, with thick superficial component. These distinct phenotypes may prove useful in the clinical setting for physicians to identify patterns of IH ulceration with increased risk of aggressive, persistent ulceration.

OBJECTIVES: To characterize the skin and mucosal findings of NEMO syndrome. METHODS: Retrospective review of clinical characteristics from a cohort of two families with mutations in IKBKG (the NEMO-encoding gene). A literature review identified 86 studies describing 192 patients with IKBKG mutations whose data were also included. SETTING: Single center with literature review. PARTICIPANTS: Patients with mutations in IKBKG from our center and reported in the literature. MAIN OUTCOMES AND MEASURES: Skin and mucosal characteristics of patients with NEMO syndrome. RESULTS: In addition to ectodermal dysplasia and recurrent infections, male patients had findings of ichthyosis, palmoplantar keratoderma, and inflammatory skin diseases. Both male and female patients had mucocutaneous ulcers and slow-to-heal chronic wounds. In combination with patients from the literature, 59% (85/144) of males had ectodermal dysplasia with anhidrosis (EDA) features, and 8% and 10% (12/144; 6/63) of males and females had dental findings, respectively. 4% (6/144) of males and 32% (20/63) of females had mucocutaneous ulcers. Ichthyosis/xerosis was present in 15% of males (21/144) but only 2% (1/63) females. Similarly, 13% (18/144) of male patients presented with dermatitis while this was reported in only 2% (1/63) of females. CONCLUSIONS: Our results both confirm and expand upon the known spectrum of mucocutaneous findings in NEMO syndrome. Further genetic studies are needed to correlate specific mutations to clinical and morphologic subtypes.

BACKGROUND AND OBJECTIVES: Cutaneous capillary malformations (CMs) describe a group of vascular birthmarks with heterogeneous presentations. CMs may present as an isolated finding or with other associations, including glaucoma and leptomeningeal angiomatosis (i.e., Sturge-Weber syndrome) or pigmentary birthmarks (i.e., phakomatosis pigmentovascularis). The use of targeted genetic sequencing has revealed that postzygotic somatic variations in GNAQ and GNA11 at codon 183 are associated with CMs. We report five patients with early-onset hypertension and discuss possible pathogenesis of hypertension. METHODS: Twenty-nine patients with CMs, confirmed GNAQ/11 postzygotic variants, and documented past medical history were identified from a multi-institutional vascular anomalies study. Early-onset hypertension was defined as hypertension before the age of 55 years. Clinical data were reviewed for evidence of hypertension, such as documentation of diagnosis or elevated blood pressure measurements. RESULTS: Five of the 29 patients identified as having GNAQ/11 postzygotic variants had documented early-onset hypertension. Three individuals harbored a GNAQ p.R183Q variant, and two individuals harbored a GNA11 p.R183C variant. All individuals had extensive cutaneous CMs involving the trunk and covering 9%-56% of their body surface area. The median age of hypertension diagnosis was 15 years (range 11-24 years), with three individuals having renal abnormalities on imaging. CONCLUSIONS: Early-onset hypertension is associated with extensive CMs harboring somatic variations in GNAQ/11. Here, we expand on the GNAQ/11 phenotype and hypothesize potential mechanisms driving hypertension. We recommend serial blood pressure measurements in patients with extensive CMs on the trunk and extremities to screen for early-onset hypertension.

BACKGROUND/OBJECTIVES: The COVID-19 pandemic prompted a rapid expansion in the use of telemedicine. This study aimed to assess the experiences of hemangioma specialists utilizing telemedicine during the COVID-19 pandemic to evaluate and manage infantile hemangiomas (IH), including perceived effectiveness of different modalities and barriers to care delivery. METHODS: Multicenter cross-sectional study asking providers to describe their experiences using telemedicine for initial evaluation of IH from March to September 2020. RESULTS: The study included 281 patients from 15 medical centers internationally. Median time from referral to evaluation was 17 days. Median physician confidence in performing evaluations via telemedicine was 95.0 (IQR 90.0-100.0). Most evaluations were performed via video communication with photographs or audio communication with photographs; when not initially available, photographs were requested in 51.4%. Providers preferred follow-up modalities that included photographs. CONCLUSIONS: Physicians with extensive expertise in managing IH are confident in their abilities to assess and manage IH via telemedicine including initiating treatment in patients without risk factors for beta-blocker therapy. There was a preference for hybrid modalities that included photographs. The data suggest that telemedicine can be effective for managing IH and may decrease wait times and improve specialist reach to underserved areas.

PURPOSE: Somatic activating variants in the PI3K-AKT pathway cause vascular malformations with and without overgrowth. We previously reported an individual with capillary and lymphatic malformation harboring a pathogenic somatic variant in PIK3R1, which encodes three PI3K complex regulatory subunits. Here, we investigate PIK3R1 in a large cohort with vascular anomalies and identify an additional 16 individuals with somatic mosaic variants in PIK3R1. METHODS: Affected tissue from individuals with vascular lesions and overgrowth recruited from a multisite collaborative network was studied. Next-generation sequencing targeting coding regions of cell-signaling and cancer-associated genes was performed followed by assessment of variant pathogenicity. RESULTS: The phenotypic and variant spectrum associated with somatic variation in PIK3R1 is reported herein. Variants occurred in the inter-SH2 or N-terminal SH2 domains of all three PIK3R1 protein products. Phenotypic features overlapped those of the PIK3CA-related overgrowth spectrum (PROS). These overlapping features included mixed vascular malformations, sandal toe gap deformity with macrodactyly, lymphatic malformations, venous ectasias, and overgrowth of soft tissue or bone. CONCLUSION: Somatic PIK3R1 variants sharing attributes with cancer-associated variants cause complex vascular malformations and overgrowth. The PIK3R1-associated phenotypic spectrum overlaps with PROS. These data extend understanding of the diverse phenotypic spectrum attributable to genetic variation in the PI3K-AKT pathway.

Activating variants in the platelet-derived growth factor receptor ß gene (PDGFRB) have been associated with Kosaki overgrowth syndrome, infantile myofibromatosis, and Penttinen premature aging syndrome. A recently described phenotype with fusiform aneurysm has been associated with mosaic PDGFRB c.1685A > G p.(Tyr562Cys) variant. Few reports however have examined the vascular phenotypes and mosaic effects of PDGFRB variants. We describe clinical characteristics of two patients with a recurrent mosaic PDGFRB p.(Tyr562Cys) variant identified via next-generation sequencing-based genetic testing. We observed intracranial fusiform aneurysm in one patient and found an additional eight patients with aneurysms and phenotypes associated with PDGFRB-activating variants through literature search. The conditions caused by PDGFRB-activating variants share overlapping features including overgrowth, premature aged skin, and vascular malformations including aneurysms. Aneurysms are progressive and can result in morbidities and mortalities in the absence of successful intervention. Germline and/or somatic testing for PDGFRB gene should be obtained when PDGFRB activating variant-related phenotypes are present. Whole-body imaging of the arterial tree and echocardiography are recommended after diagnosis. Repeating the imaging study within a 6- to 12-month period after detection is reasonable. Finally, further evaluation for the effectiveness and safety profile of kinase inhibitors in this patient population is warranted.

BACKGROUND: High-flow vascular stains (HFVS) are lesions that have the appearance of capillary malformations/port wine stains but are associated with increased arterial flow. OBJECTIVE: To identify features of HFVS that differentiate them from typical "slow-flow" port wine stains. METHODS: Retrospective multicenter cohort study of HFVS evaluated across 7 centers was conducted. HFVS were characterized by clinical features (warmth, thrill, rapid capillary refill), radiologic findings (fast flow), or mutations associated with capillary malformation-arteriovenous malformation syndrome. Investigators reviewed photographs. RESULTS: The study reviewed 70 patients with HFVS (47 multifocal and 23 solitary). Most were flat (77%), warm to the touch (60%), and red or pink-red in color (35%), with heterogeneous color saturation (73%) and well-defined borders (71%). Regional soft tissue swelling/overgrowth was common (47%). Head and neck location was most common (38%). Among 34 HFVS with photographic review over time, all demonstrated changes in appearance. LIMITATIONS: Retrospective design, recall bias, lack of standardized time points or visual analog scale, and image variability. CONCLUSION: Heterogeneity of stain color saturation, warmth to touch, peripheral pallor, and overgrowth/soft tissue swelling help distinguish HFVS from port wine stains. Darkening of color and increased border demarcation may develop over time. These findings raise suspicion for HFVS and provide an indication to assess for extracutaneous involvement.

BACKGROUND: Initial propranolol recommendations for infantile hemangioma published in 2013 were intended as provisional best practices to be updated as evidence-based data emerged. METHODS: A retrospective multicenter study was performed to evaluate utility of prolonged monitoring after first propranolol dose and escalation(s). Inclusion criteria included diagnosis of hemangioma requiring propranolol of greater than or equal to 0.3 mg/kg per dose, younger than 2 years, and heart rate monitoring for greater than or equal to 1 hour. Data collected included demographics, dose, vital signs, and adverse events. RESULTS: A total of 783 subjects met inclusion criteria; median age at initiation was 112 days. None of the 1148 episodes of prolonged monitoring warranted immediate intervention or drug discontinuation. No symptomatic bradycardia or hypotension occurred during monitoring. Mean heart rate change from baseline to 1 hour was -8.19/min (±15.54/min) and baseline to 2 hours was -9.24/min (±15.84/min). Three preterm subjects had dose adjustments because of prescriber concerns about asymptomatic vital sign changes. No significant difference existed in pretreatment heart rate or in heart rate change between individuals with later adverse events during treatment and those without. CONCLUSION: Prolonged monitoring for initiation and escalation of oral propranolol rarely changed management and did not predict future adverse events. Few serious adverse events occurred during therapy; none were cardiovascular.

BACKGROUND/OBJECTIVES: Infantile hemangiomas (IHs) are common benign vascular tumors of infancy. IHs tend to grow in the first few months of life and then gradually involute over years, often leaving fibrofatty residua or textural changes in their place. Classically, these lesions are painless throughout their entire natural history; however, we now report on seven patients with involuted IH with intermittent but persistent sensory symptoms. METHODS: This is a multicenter case series in which members of the Birthmarks Focused Study Group of the Pediatric Dermatology Research Alliance (PeDRA) and the Hemangioma Investigator Group contributed patients with IH and dysesthesias from their clinical practices. Charts were then reviewed to document clinical details. RESULTS: Seven patients were included, presenting at an average age of 14.6 years (range 3-48 years) for complaints related to discomfort in the region of involuted IH. The majority (6/7) reported pain or tenderness to the area. One patient reported pruritus. All patients reported intermittent symptoms. The length of symptoms ranged between 4 months and 5 years. Treatment was attempted in 5/7 patients. Ice, oral propranolol, topical capsaicin, and intralesional triamcinolone partially improved symptoms. CONCLUSIONS: Persistent cutaneous dysesthesias were present in seven patients, in most cases many years after completion of involution. Further research is needed to fully elucidate the pathophysiology and optimal treatments for this IH complication.

BACKGROUND: In their early phase, infantile hemangiomas (IH) can sometimes be difficult to differentiate from port-wine birthmarks (PWB). Until recently, inexpensive diagnostic tools have not been readily available. OBJECTIVE: To determine the diagnostic utility of widely available colorimetric technology when differentiating PWB from IH in photographs of infants less than 3 months old. METHODS: Multi-center, retrospective analysis of RGB (red, green, and blue) and HSL (hue, saturation, lightness) values collected using electronic colorimeters from images of clinically confirmed untreated IH or PWB. Subgroup analysis of flat vascular birthmarks was subsequently performed. RESULTS: Images of 119 IH (specifically, 45 flat IH) and 59 PWB were identified. PWB had significantly (P < .001) higher RGB values of all primary colors, most notably for blue and green (mean difference: >50), irrespective of thickness. RGB or RGB with HSL values had an excellent accuracy (90%), sensitivity (92%), specificity (98%), and positive predictive value (98%) when discriminating PWB from flat IH. IH could be distinctly clustered from PWB when combining their RGB with HSL values. CONCLUSION: Electronic colorimeters with emphasis on blue and green values, are able to differentiate PWB from IH, irrespective of thickness, with a high degree of accuracy. A larger scale evaluation is now required.

BACKGROUND/OBJECTIVES: Malignant rhabdoid tumors (MRT) are highly aggressive tumors with a predilection for the kidney, central nervous system, and soft tissues that usually affect young children under three years of age. Primary presentation in the skin is rarely reported, and features of the cutaneous manifestations are not well described. We report six cases of metastatic MRT that first manifested with congenital nodules and masses in the skin. METHODS: Retrospective case series. RESULTS: The cutaneous presentation of MRT may be heterogeneous and can present with solitary or multifocal skin lesions. Congenital polypoidal and papillomatous plaques, including those with histologic features of neurovascular hamartoma, appear to be a unique presentation of MRT in the infant. CONCLUSIONS: Malignant rhabdoid tumor should be considered in the differential diagnosis of unusual skin tumors in neonates and infants.
