introduction: pulsed dye laser (pdl) is an important treatment for superficial infantile hemangioma, but few studies report on its cellular mechanism. the aim of this study was to evaluate alterations of serum vascular endothelial growth factor (vegf) level in infantile hemangioma (ih) patients after laser treatment and effects of pdl irradiation on human umbilical vein endothelial cells (huvec...

Infantile hemangioendothelioma is a severe disease with a high mortality. It is characterized by multiple hemangioma affecting the skin and visceral organs. We report that high doses of methylprednisolone pulse therapy improved symptoms and signs of infantile hemangioendothelioma in a male neonate, and completely resolved the hepatic and cutaneous hemangioendothelioma on follow up.

Infantile periocular hemangiomas (IPH) are common benign vascular tumors that present early in childhood. They typically show a rapid nonlinear growth pattern a few weeks after birth during a proliferative phase, then continue with an involution phase and may result in serious ocular or systemic complications. Theses tumors may present in a range of small isolated lesions to multiple, diffuse i...

BACKGROUND Primary osseous hemangiomas of the facial skeleton mimic malignancy. Their location in maxillary sinus, especially in infants is extremely rare. CASE CHARACTERISTICS 1- month-old full term boy with maxillary swelling. OBSERVATIONS Biopsy from oral route revealed hemangioma showing vascular channels lined by endothelial cells. Patient improved on oral steroids. MESSAGE Hemangiom...

We read with interest the letter sent by Yoon et al (1) about transarterial embolization of a cervicofacial hemangioma associated with Kasabach–Merritt (KM) syndrome in a premature neonate. There are some facets of the letter that warrant further comments, namely the association of the KM phenomenon with vascular tumors and the use of proper consensus-approved terminology adopted by the Interna...

BACKGROUND Infantile hemangiomas are benign vascular tumors primarily found on the skin in 10% of the pediatric population. The etiology of this disease is largely unknown and while large scale genomic studies have examined the transcriptomes of infantile hemangioma tumors as a whole, no study to date has compared the global gene expression profiles of pure infantile hemangioma endothelial cell...

Infantile hemangioma is an endothelial tumor that grows rapidly after birth but slowly regresses during early childhood. Initial proliferation of hemangioma is characterized by clonal expansion of endothelial cells (ECs) and neovascularization. Here, we demonstrated mRNA encoding CD133-2, an important marker for endothelial progenitor cells (EPCs), predominantly in proliferating but not involut...

Infantile hemangioma (IH), the most common tumor of infancy, is characterized by an initial proliferation during infancy followed by spontaneous involution over the next 5-10 years, often leaving a fibro-fatty residuum. IH is traditionally considered a tumor of the microvasculature. However, recent data show the critical role of stem cells in the biology of IH with emerging evidence suggesting ...

Infantile hemangioma is a common benign vascular neoplasm characterized by endothelial cell proliferation. Hemangiomas are one of themost common tumors of infancy and typically present on the head, neck, trunk or extremities.1 There are currently no published cases of clitoral hemangiomas presenting in an infant. In our report, we will describe a five-month old female who presented with a clito...

Hemangiomas are benign tumors of the capillary endothelium involved in varied clinical and pathologic entities. Congenital hemangioma is quite rare compared to infantile hemangioma. Hemangiomas rarely occur in bone. Intraosseous hemangiomas are most commonly found in the vertebral column and skull. The mandible is the most frequently affected skull bone. Intraosseous hemangiomas commonly presen...
