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...

BACKGROUND: Curcumin has been used as an alternative medicine for the treatment of infantile hemangiomas (IHs); however, the mechanism underlying the effectiveness of curcumin in IHs remains largely unclear. METHODS: In this study, we isolated primary human hemangioma endothelial cells (HemECs) from fresh surgical specimens of 3 patients. We treated HemECs by curcumin and investigated the alterations in proliferative and apoptotic signaling pathways with cell counting kit-8, flow cytometry, western blotting, immunofluorescence, and real-time polymerase chain reaction...

Tooth development is regulated by multiple genetic pathways, which ultimately drive the complex interactions between the oral epithelium and mesenchyme. Disruptions at any time point during this process may lead to failure of tooth development, also known as tooth agenesis (TA). TA is a common craniofacial abnormality in humans and represents the failure to develop one or more permanent teeth. Many genes and potentially subtle variants in these genes contribute to the TA phenotype. We report the clinical and genetic impact of a rare homozygous ANTXR1 variant (c...

BACKGROUND: Infantile hemangiomas (IH) with functional or cosmetic concerns necessitate systemictreatment for which propranolol is the preferred treatment. However, the mechanism ofaction is unknown. Mouse models suggest the angiopoietin-2 (Ang2)/Tie-2 system isimplicated. Ang2 can promote endothelial growth or induce apoptosis depending on thepresence of vascular endothelial growth factor (VEGF). This pilot study investigates thesaliva Ang2 levels in infants with IH treated with and without systemic propranolol...

Infantile hemangiomas are the most common benign tumors of infancy, characterized by unregulated angiogenesis and endothelial cells with high mitotic rate. Although spontaneous regression occurs, sometimes treatment is required and alternatives to corticosteroids should be considered to reduce side effects. Imiquimod is an imidazoquinoline, approved for some skin pathologies other than hemangioma. It is proposed that the effectiveness of imiquimod comes from the activation of immune cells at tumor microenvironment...

BACKGROUND: Oral propranolol is the gold-standard to treat infantile hemangiomas. There is better efficacy and a lower risk of sequelae if therapy is started before the end of the growth phase, but most children are referred too late. Herein, we report the first study to investigate the delay and its associated factors when referring infants with infantile hemangiomas that need propranolol therapy. OBJECTIVES: The primary objective was to determine the delay in referral (time between age at referral [first phone contact] and the optimal age for referral (fixed at 75 days)...

Developmental anomalies of the skull base may present in childhood or as an adult. The most common pathologies include dermoid, encephalocele, and glioma. Encephaloceles may present as part of a syndrome. Other entities include infantile hemangiomas and teratoma. Endoscopic techniques provide a less invasive and morbid option for treatment. Proper evaluation and treatment is necessary to prevent complications such as meningitis.

Infantile hepatic hemangioma (IHH) and mesenchymal hamartoma (MH) form the first and second most common benign hepatic tumors in children. In this case report, we present a newborn child in whom a growing hepatic mass was discovered at the age of 7 days. She suffered also from anemia, respiratory and renal failure. No signs of heart disease or cutaneous lesions were detected. Alpha-fetoprotein was elevated for her age (3562.2 ng/ml). Imaging studies showed multifocal large cystic lesions associated with heterogeneous small solid lesions with arterial enhancement of the liver...

Background: Most of infantile hemangiomas involute into fibrofatty tissue in childhood, which indicates adipogenesis during this period. Mesenchymal stem cells (MSCs) contribute to the adipogenesis in IH. In this study, we investigated the effects of overexpression of PPAR-γ2 gene on the adipogenic differentiation of Hemangioma-derived MSCs (Hem-MSCs), and discussed the possibility of targeted therapy via PPAR-γ pathway. Methods: MSCs were isolated from proliferating hemangioma by their selective adhesion to plastic culture dishes...

Topical timolol maleate has recently gained popularity as a treatment for superficial infantile hemangiomas, but calculating a safe dose of timolol can be time consuming, which may limit the medication's use in fast-paced clinical environments. This report offers a simplified calculation of the maximum daily safe dosage as 1 drop of medication per kilogram of body weight.

INTRODUCTION: The primary management of infantile hemangioma (IH) has changed since 2008, with the initiation of propranolol. The change that propranolol has affected on resource utilization is unknown. MATERIALS AND METHODS: The Kids' Inpatient Database (KID) in 2003, 2006, 2009, and 2012 was queried for ICD-9 codes for IH in children under age three. The number of patients undergoing the following procedures of interest: tracheostomy, tracheoscopy and laryngoscopy with biopsy, and excision of skin lesion were evaluated...

CASE: We report a case of kaposiform hemangioendothelioma (KHE) of the scapula in a 2-year-old boy with motor and sensory abnormalities of the left upper extremity, suggesting brachial plexus involvement. The locally invasive nature prevented resection; sirolimus therapy resulted in improvement of the motor and sensory impairment, as well as decreased tumor size on imaging. CONCLUSION: Osseous infiltration of KHE is known to occur, but its primary presentation in bone without skin involvement is rare and diagnostically challenging...

Infant hemangioma, the most common benign tumor in children, is characterized by rapid proliferation, followed by slower spontaneous involution. However, some patients with facial segmental hemangioma are associated with PHACE syndrome. PHACE syndrome is characterized by vascular nerve and vascular cutaneous lesions of multiple systemic systems, often resulting in structural and functional impairments. Recent studies have demonstrated that the possible pathogeneses of PHACE syndrome mainly include hypoxia, abnormality of mesodermal vascular endothelial cells, genetic abnormality, and abnormality of interstitial mesenchymal stem cells...
