Infantile hemangioma (IH) is a benign tumor that is formed by aberrant angiogenesis and that undergoes spontaneous regression over time. Propranolol, the first-line therapy for IH, inhibits angiogenesis by downregulating the activation of the VEGF pathway, which is hyperactivated in IH. However, this treatment is reportedly ineffective for 10% of tumors, and 19% of patients relapse after propranolol treatment. Both pro-angiogenic and anti-angiogenic factors regulate angiogenesis, and PEDF is the most effective endogenous anti-angiogenic factor...

Genetic lesions in proto-oncogenes result in the perturbation of angiogenesis, the formation of neovessels from a pre-existing microvasculature. Similarly, the subversion of tumor suppressor genes promotes tumor vascularization. Excessive neovessel formation is associated with various neoplasms such as infantile hemangiomas (IH). Hemangiomas are the most common tumors in pediatric patients and at present have no definitive treatment. The pathogenesis of IH is not well understood; however, both vasculogenesis and angiogenesis are associated with hemangioma genesis...

BACKGROUND: Infantile hemangiomas (IH) are the most common benign vascular tumors in childhood. Approximately 10% to 15% of these tumors require drug or surgical intervention. There are many options for IH treatment, of which propranolol is currently considered the gold standard. This study aims to compare the therapeutic results of 2 distinct drugs (ethanolamine oleate and propranolol), in order to increase the available therapeutic arsenal for the treatment of IH, thereby benefiting a larger group of patients...

Infantile hemangiomas undergo rapid growth during early infancy followed by gradual involution. Infantile hemangiomas sometimes impair vital functions or cause disfigurement. Thirty-two Japanese patients between the ages of 1 and 4 months with proliferating infantile hemangiomas received oral propranolol on an outpatient basis. The success rate (complete or nearly complete resolution) at week 25 was 56% (18/32). Two patients dropped out because of a personal reason and moving out. Recurrence after termination of treatment was seen in six patients...

INTRODUCTION: The life cycle of infantile hemangioma (IH) and secretion of follicle-stimulating hormone (FSH) are identical. We previously have shown that IH contains the FSH receptor (FSHR). The purpose of this study was to identify which cell type(s) in IH expresses FSHR. METHODS: Human proliferating IH tissues obtained during a clinically indicated surgical procedure were used. Paraffin sections and isolated cell populations (endothelial, pericyte, stem cell) were subjected to immunofluorescence for FSHR...

Betablockers are used for decades in the treatment of cardiovascular diseases. Recently, the repurposing of the wide spectrum betablocker propranolol revolutionized the infantile hemangioma management. Besides, betablockers have been shown to significantly improve the prognosis of melanoma patients. Blocking the adrenergic receptors blocks the stress-induced tumorigenic pathways. Propranolol inhibits melanoma by downregulating the tumor angiogenesis but also tumor cell proliferation, invasiveness and local immune suppression...

Infantile metastatic choriocarcinoma is a rare tumor of placental origin that can be observed with or without maternal metastases. A single cutaneous mass may be the only clinically observed sign. Reports of imaging findings are scarce given the extreme rarity of the tumor, and the disease can be rapidly fatal in the absence of prompt diagnosis. In order to promote timely consideration for this malignancy as a differential consideration in the approach to skin lesions in infancy, we present the findings of this neoplasm in an infant...

BACKGROUND: Propranolol is the mainstay of treatment for infantile hemangioma. Despite its good safety profile, it is not risk-free. Guidelines for propranolol initiation and monitoring have been suggested, but protocols vary among practitioners. OBJECTIVE: This study sought to assess the prevalence of adverse events and clinically significant fluctuations in hemodynamic parameters in children with infantile hemangioma during initiation of treatment with propranolol in a day-hospitalization setting...

Superficial vascular anomalies constitute a large group of malformative and tumoral conditions developed from all types of vessels. Vascular tumors are the result of cellular hyperplasia, whereas vascular malformations (VMs) are constituted of dysplastic vessels. The classification from International Society for the Study of Vascular Anomalies (ISSVA) is based on this pathogenic difference. The most common vascular tumor is infantile hemangioma, which treatment, when necessary, is propranolol. Congenital hemangiomas and tumors that might be complicated with Kasabach-Merritt phenomenon, i...

The etiopathogenesis of infantile hemangioma has not been well understood, and it is accepted that angiogenic mediator dysregulation is the main contributor to the abnormal hemangioma capillary formation. The role of NDRG1, a hypoxia-inducible protein; FOXOs, which are tumor suppressor proteins; and the mTOR complex 2 pathway in infantile hemangioma have not been studied yet. The purpose of this study was to investigate NDRG1 and FOXO1 expression in the infantile hemangioma and the correlation of these proteins with proliferation and involution...

OBJECTIVES: A current therapeutic challenge of vascular lesions is that they do not always respond effectively to laser treatment. Information on targeted vessels could potentially be used to guide laser treatments. Optical coherence tomography (OCT) is a useful tool for the non-invasive imaging of tissues, including skin hemangiomas and port wine birthmarks. Dynamic OCT is able to rapidly characterize cutaneous blood vessels. The primary goal of this study was to demonstrate the ability of bedside OCT to image (i) overall vessel pattern; (ii) individual vessel morphology, diameter and depth; and (iii) total vessel density as a function of depth in infantile hemangiomas and port wine birthmarks (PWB)...

Vascular tumors in infants present a diagnostic and treatment dilemma for both clinicians and pathologists. Infantile hemangioma, the most common vascular tumor in infants, can be confused for other less common vascular tumors in infants. Correct and timely diagnosis is important, as some vascular tumors can be associated with life-threatening coagulopathy. We present the cases of 5 vascular tumors that have clinical and histologic overlap: infantile hemangioma, pyogenic granuloma, noninvoluting congenital hemangioma, tufted angioma, and kaposiform hemangioendothelioma...

Infantile hemangioma (IH) is the most common vascular tumour in infants. The pathogenesis of IH is complex and poorly understood. Therefore, achieving a deeper understanding of IH pathogenesis is of great importance. Here, we used the Ribo-Zero RNA-Seq and HiSeq methods to examine the global expression profiles of protein-coding transcripts and non-coding RNAs, including miRNAs and lncRNAs, in IH and matched normal skin controls. Bioinformatics assessments including gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) pathway analyses were performed...

Infantile choriocarcinoma (ICC) is a rare, highly malignant form of gestational trophoblastic neoplasia. Rapid diagnosis and initiation of treatment are paramount in reaching a successful outcome. Patients with these tumors typically present with a triad of anemia, hepatomegaly, and precocious puberty. Cutaneous manifestations of ICC are extraordinarily rare with few documented cases. Here, we describe a male neonate who presented to our Dermatology clinic with a rapidly growing, markedly vascular glabellar mass associated with abnormal laboratory values suggestive of Kasabach-Merritt phenomenon...

Infantile hepatic hemangiomas (IHH), particularly of the diffuse subtype, can in severe cases be associated with hepatic and cardiac failure, compartment syndrome, and consumptive hypothyroidism. Early recognition and treatment of these pathologies is paramount in order to minimise the risk of longterm sequelae. We report an interesting case of a female infant who presented with systemic compromise, in the absence of large or obvious cutaneous infantile hemangiomas (IH). Imaging identified innumerable hepatic hemangiomas, consistent with diffuse infantile hepatic hemangiomatosis...

Currently, propranolol is the most preferred systemic therapy for problematic infantile hemangiomas (IHs). However, the side effects such as bronchial hyperreactivity may be intolerable. The aim of this study was to evaluate the frequency, risk factors and management of intolerable side effects (ISEs) during propranolol therapy. In total, 1260 children were studied. The incidence of ISEs was 2.1% (26 patients). Severe sleep disturbance was the most common reason for propranolol cessation, accounting for 65...

The most common tumors in children are infantile hemangiomas which could cause morbidity and severe complications. The development of novel alternative drugs to treat infantile hemangiomas is necessary, since Hemangeol is the only US Food and Drug Administration-approved drug for infantile hemangiomas. However, Hemangeol has several disadvantages, including a high frequency of administration and adverse effects. Rapamycin is a well‑established antiangiogenic drug, and we have previously developed rapamycin lipid polymer nanoparticles (R‑PLNPs) as a local sustained‑release drug delivery system to achieve controlled rapamycin release and to decrease the frequency of administration and side effects of rapamycin...

Infantile hemangiomas are the most common tumors affecting children. Although infantile hemangiomas are benign, they could result in morbidity and mortality. The only US Food and Drug Administration-approved drug for infantile hemangiomas is propranolol hydrochloride (Hemangeol™); however, its adverse effects and high frequency of administration hamper its clinical application. Vascular endothelial growth factor receptor (VEGFR) is crucial to the angiogenesis of infantile hemangiomas, and thus it is considered a valuable therapeutic target for infantile hemangiomas...

Background: Though infantile hemangiomas are the most common benign tumor of infancy, their etiopathogenesis is not fully understood. Some studies report a diagnostic role for vascular endothelial growth factor (VEGF), but such studies are lacking from India. Aims: To study the clinicoepidemiological profile of infantile hemangiomas, to estimate and compare the serum levels of VEGF in infantile hemangiomas and controls, and to determine correlations between serum levels of VEGF and growth characteristics of infantile hemangiomas...

Background: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare vascular proliferative disorder mainly located in the periauricular region. The etiopathogenesis of ALHE is unknown, and it is still controversial as to whether the entity represents a benign vascular neoplasm or an inflammatory process. Aim: Recently, the intracytoplasmic staining pattern of Wilms tumor 1 (WT1) on immunohistochemistry has highlighted true vascular neoplasms, such as microvenular hemangioma, tufted angioma, and spindle cell hemangioma, which has made it helpful to distinguish ALHE from vascular malformations, as there is a negative staining pattern in the other entities...
