Objectives: Infantile hemangiomas (IHs) are common; some cases require timely referral and treatment to prevent complications. We developed and validated a reliable instrument for timely and adequate referral of patients with IH to experts by nonexpert primary physicians., Methods: In this multicenter, cross-sectional, observational study, we used a 3-stage process: (1) development of the Infantile Hemangioma Referral Score (IHReS) tool by IH experts who selected a representative set of 42 IH cases comprising images and a short clinical history, (2) definition of the gold standard for the 42 cases by a second independent committee of IH experts, and (3) IHReS validation by nonexpert primary physicians using the 42 gold standard cases., Results: A total of 60 primary physicians from 7 different countries evaluated the 42 gold standard cases (without reference to the IHReS tool); 45 primary physicians evaluated these cases using the IHReS questionnaire, and 44 completed retesting using the instrument. IHReS had a sensitivity of 96.9% (95% confidence interval 96.1%-97.8%) and a specificity of 55.0% (95% confidence interval 51.0%-59.0%). The positive predictive value and negative predictive value were 40.5% and 98.3%, respectively. Validation by experts and primary physicians revealed substantial agreement for interrater reliability and intrarater repeatability., Conclusions: IHReS, a 2-part algorithm with a total of 12 questions, is an easy-to-use tool for primary physicians for the purpose of facilitating correct and timely referral of patients with IH. IHReS may help practitioners in their decision to refer patients to expert centers., Competing Interests: POTENTIAL CONFLICT OF INTEREST: Dr Léauté-Labrèze is a consultant and clinical trial investigator for Pierre Fabre and is a member of the Infantile Hemangioma European Task Force (IHETF) and received consultant fees.

Hepatic hemangioma (HH) is a common asymptomatic, self-limiting benign vascular tumor of the liver in neonates. Although complicated HHs are rare, they have significant risks of morbidity and mortality, especially during the perinatal period. Because of the high risks of complications from surgical interventions, there is an unmet need for effective medical therapy. We report 2 neonates with life-threatening HH who were evaluated for a liver transplant before being treated successfully with combined medical therapy, which included sirolimus, corticosteroids, and propranolol., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Infantile hemangiomas (IHs) occur in as many as 5% of infants, making them the most common benign tumor of infancy. Most IHs are small, innocuous, self-resolving, and require no treatment. However, because of their size or location, a significant minority of IHs are potentially problematic. These include IHs that may cause permanent scarring and disfigurement (eg, facial IHs), hepatic or airway IHs, and IHs with the potential for functional impairment (eg, periorbital IHs), ulceration (that may cause pain or scarring), and associated underlying abnormalities (eg, intracranial and aortic arch vascular abnormalities accompanying a large facial IH). This clinical practice guideline for the management of IHs emphasizes several key concepts. It defines those IHs that are potentially higher risk and should prompt concern, and emphasizes increased vigilance, consideration of active treatment and, when appropriate, specialty consultation. It discusses the specific growth characteristics of IHs, that is, that the most rapid and significant growth occurs between 1 and 3 months of age and that growth is completed by 5 months of age in most cases. Because many IHs leave behind permanent skin changes, there is a window of opportunity to treat higher-risk IHs and optimize outcomes. Early intervention and/or referral (ideally by 1 month of age) is recommended for infants who have potentially problematic IHs. When systemic treatment is indicated, propranolol is the drug of choice at a dose of 2 to 3 mg/kg per day. Treatment typically is continued for at least 6 months and often is maintained until 12 months of age (occasionally longer). Topical timolol may be used to treat select small, thin, superficial IHs. Surgery and/or laser treatment are most useful for the treatment of residual skin changes after involution and, less commonly, may be considered earlier to treat some IHs., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

Infantile hemangiomas (IHs) are the most common tumors of childhood. Unlike other tumors, they have the unique ability to involute after proliferation, often leading primary care providers to assume they will resolve without intervention or consequence. Unfortunately, a subset of IHs rapidly develop complications, resulting in pain, functional impairment, or permanent disfigurement. As a result, the primary clinician has the task of determining which lesions require early consultation with a specialist. Although several recent reviews have been published, this clinical report is the first based on input from individuals representing the many specialties involved in the treatment of IH. Its purpose is to update the pediatric community regarding recent discoveries in IH pathogenesis, treatment, and clinical associations and to provide a basis for clinical decision-making in the management of IH., (Copyright © 2015 by the American Academy of Pediatrics.)

Infantile hemangiomas (IHs) are the most common vascular tumors of childhood, affecting ~5% of all infants. Although most lesions proliferate and then involute with minimal consequence, a significant minority can be disfiguring, functionally significant, or, rarely, life-threatening. Recent discoveries concerning hemangioma pathogenesis provide both an improved understanding and more optimal approach to workup and management. Important detrimental associations can be seen with IH, such as significant structural anomalies associated with segmental IH. Standards of care have dramatically changed evaluation and management of hemangiomas. The goal of timely recognition and therapy is to minimize or eliminate long-term sequelae. New modalities, such as oral propranolol, provide the caregiver with better therapeutic options, which can prevent or minimize medical risk or scarring, but the side effect profile and risk-benefit ratio of such interventions must always be evaluated before instituting therapy.

Background and Objectives: Infantile hemangiomas (IH) are recognized as growing rapidly during the first months of life, but details of early growth before 3 months of age have not been well-characterized. Our goal was to study early IH growth by using parental photographs of infant children with facial IHs to better understand early hemangioma growth, with the aim of improving guidance for physicians and parents of infants with high-risk IH., Methods: Serial images of 30 infants showing IH at intervals of 1 to 2 weeks up to 6 months were analyzed for characteristics of color, thickness, and distortion of anatomic landmarks. The presence or absence of an IH precursor at birth was noted. Mean scores per age interval were compiled. Results were analyzed by using signed rank test. An assessment of "optimal time for referral" was made., Results: IH growth was nonlinear; most rapid growth occurred between 5.5 and 7.5 weeks of age. The mean "optimal age for referral" was 4 weeks of age. Hemangioma precursors were present at birth in 65% of patients., Conclusions: The most rapid hemangioma growth occurs before 8 weeks of age, much earlier than previously appreciated. Specialty evaluation and initiation of treatment, however, typically occur after the age of most rapid growth. Our findings suggest a need for a paradigm shift in the timing of referral and initiation of treatment of high-risk IH so that therapy can be initiated before or early in the course of most rapid growth, rather than after it is already completed.

Objectives: Infantile hemangiomas often are inapparent at birth and have a period of rapid growth during early infancy followed by gradual involution. More precise information on growth could help predict short-term outcomes and make decisions about when referral or intervention, if needed, should be initiated. The objective of this study was to describe growth characteristics of infantile hemangioma and compare growth with infantile hemangioma referral patterns., Methods: A prospective cohort study involving 7 tertiary care pediatric dermatology practices was conducted. Growth data were available for a subset of 526 infantile hemangiomas in 433 patients from a cohort study of 1096 children. Inclusion criteria were age younger than 18 months at time of enrollment and presence of at least 1 infantile hemangioma. Growth stage and rate were compared with clinical characteristics and timing of referrals., Results: Eighty percent of hemangioma size was reached during the early proliferative stage at a mean age of 3 months. Differences in growth between hemangioma subtypes included that deep hemangiomas tend to grow later and longer than superficial hemangiomas and that segmental hemangiomas tended to exhibit more continued growth after 3 months of age. The mean age of first visit was 5 months. Factors that predicted need for follow-up included ongoing proliferation, larger size, deep component, and segmental and indeterminate morphologic subtypes., Conclusions: Most infantile hemangioma growth occurs before 5 months, yet 5 months was also the mean age at first visit to a specialist. Recognition of growth characteristics and factors that predict the need for follow-up could help aid in clinical decision-making. The first few weeks to months of life are a critical time in hemangioma growth. Infants with hemangiomas need close observation during this period, and those who need specialty care should be referred and seen as early as possible within this critical growth period.

Objectives: Infantile hemangiomas are the most common tumor of infancy. Risk factors for complications and need for treatment have not been studied previously in a large prospective study. This study aims to identify clinical characteristics associated with complications and the need for therapeutic intervention., Patients and Methods: We conducted a prospective cohort study at 7 US pediatric dermatology clinics with a consecutive sample of 1058 children, aged < or = 12 years, with infantile hemangiomas enrolled between September 2002 and October 2003. A standardized questionnaire was used to collect data on each patient and each hemangioma, including clinical characteristics, complications, and treatment., Results: Twenty-four percent of patients experienced complications related to their hemangioma(s), and 38% of our patients received some form of treatment during the study period. Hemangiomas that had complications and required treatment were larger and more likely to be located on the face. Segmental hemangiomas were 11 times more likely to experience complications and 8 times more likely to receive treatment than localized hemangiomas, even when controlled for size., Conclusions: Large size, facial location, and/or segmental morphology are the most important predictors of poor short-term outcomes as measured by complication and treatment rates.

During the past 10 years, 25 infants with alarming hemangiomas--lesions that impaired important functions and were life threatening, especially when there was visceral involvement--have been treated. A vascular mark was present at birth in 68% of these infants. Visceral hemangiomas were associated with bulky cervicocephalic hemangiomas or with small hemangiomas scattered over the body. Among the 25 infants, 12 had laryngeal hemangiomas, 3 had hepatic hemangiomas, and 1 had gastrointestinal hemangiomatosis. Ocular sequelae, malocclusion, and cutaneous distortion were the most important functional problems. Corticosteroid treatment was used for 23 of 25 infants with alarming hemangiomas. There was a varied treatment response: total failure (30% of the patients); excellent, dramatic, rapid improvement (30% of the patients); and moderate, doubtful response, with the natural course of the disease remaining unaltered (40% of the infants). Arterial embolization, used in 6 infants, gave inconstant results. Cardiac failure, frequently associated with large cutaneous hemangiomas and always seen with hepatic multinodular hemangiomas, required digitalization. In some cases arterial embolization reduced the increased cardiac output. Liver hemangiomas had a high mortality; all 3 infants with hepatic involvement died.

Indications for and results and complications of embolization of lesions of the head and neck were analyzed retrospectively. The procedures were performed since 1980 on an emergent or urgent basis in 30 infants and children by an experienced interventional neuroradiologist in Bicetre, France. Indications for embolization included hemorrhage, occular occlusion, respiratory obstruction, CNS complications or potential complications, interference with nutrition, and functional impairment related to the effect of the lesion on the developing facial skeleton and teeth. The specific lesions included seven hemangiomas (palpebral, subglottic, and nasal) and 20 vascular malformations (maxillofacial, auricular, dural, cerebral [including three vein of Galen malformations] and spinomedullary). Embolization was efficacious in 28 of 30 patients. Hemangiomas (potentially involutive tumors) responded dramatically with arrest of the proliferative phase and shrinking of the mass. Combined hemovascular lymphatic malformations (hemolymphangiomas) of the tongue demonstrated a variable decrease in size. High-flow evolutive arteriovenous malformations involving the teeth and dura were controlled but required multiple embolizations. One infant with a vein of Galen arteriovenous malformation died. Three local complications occurred in two patients. No cerebral ischemic or femoral artery complications occurred.

During the past 15 years we have managed six children with capillary hemangiomas in association with consumptive coagulopathy--the Kasabach-Merritt syndrome. Their ages when first seen ranged from 2 weeks to 4 years with a mean of 19 months. In three of the patients, the hemangiomas remained small for many months and then suddenly enlarged and hemorrhagic diatheses appeared. The duration of the thrombocytopenia ranged from 5 to 20 months, a time span that in some of the patients was influenced by the type of treatment used. Each patient received a variety of therapies including the following: medications to control the coagulopathy; mechanical, cytolytic, and pharmacologic treatment to eradicate the lesion; and blood product support with platelets and cryoprecipitate for severe bleeding. A prompt elevation of the platelet count occurred in three of the patients after the lesion was biopsied. Subtotal resection of the lesion resulted in an immediate increase of the platelet count in one patient. A transient increase in platelet counts and fibrinogen levels was observed in another patient following several embolizations of a portion of the hemangioma. Other modes of therapy were difficult to evaluate, especially because the same therapy applied at different times in the same patient effected a different type of response. Eventually, all of the patients experienced resolution of their lesions and, with this, concomitant reversal of the coagulopathy.

Three cutaneous vascular lesions of childhood (the spider angioma [nevus araneus], the strawberry hemangioma, and the port wine stain) are reviewed, with particular emphasis on the present and future role of laser therapy in their management.

From 1958 through 1978, 13 patients with diffused hepatic hemangioma were seen at Childrens Hospital of Los Angeles. Based on this experience and review of the literature, liver biopsy in these patients was found to be unnecessary and hazardous. Diagnosis can be made by dynamic and static hepatic scintigraphy and selective hepatic arteriography. Nonsurgical measures including treatment of congestive heart failure, corticosteroids, and radiotherapy are recommended for treatment of these patients. Surgery should be reserved only for emergencies, such as rupture of the tumor and hemorrhage, or for patients with severe congestive heart failure unresponsive to medical treatment. For the latter group of patients hepatic artery ligation is recommended. Hepatic artery embolization has recently been used, but experience with this new mode of therapy is limited.
