Proteus syndrome is a rare congenital disorder comprised of subcutaneous and internal hamartomas, miscellaneous skin and vascular nevi, skeletal and nervous system and eye malformations, with characteristic manifestations including hemihypertrophy, local gigantism, macrodactyly and cerebriform thickness of soles and palms. A 23 year-old man with diagnosis of proteus syndrome had sever ane...

Vascular anomalies are among the most common congenital and neonatal dysmorphogenesis, which are separated into hemangiomas and vascular malformations. They can occur in various areas throughout the body, with 60% being located in the head and neck. The true mechanism of pathogenesis of vascular anomalies is still unclear. Various treatment methods have been reported, and there are still contro...

Pediatric vascular tumors and malformations, comprising a broad category of lesions often referred to as vascular anomalies, are a heterogenous group of clinicopathologically distinct entities. Pathologists, clinicians, and radiologists have traditionally lumped these lesions under the generic term, hemangioma, sometimes qualified by modifiers, such as capillary or cavernous. Advances in unders...

The Proteus syndrome comprises an association of asymmetrical overgrowth of almost any part of the body, verrucous epidermal naevi, vascular malformations and lipoma-like subcutaneous hamartoma. Both sexes are affected with equal frequency and severity and it is not transmitted genetically. Here a 16-year-old man with asymmetric overgrowth of the extremities, macrodactyly, cerebriform hypertrop...

With the growth of the developing embryonic brain, increasing requirements for oxygen and metabolic substrates demand a more comprehensive and complex vascular system. Covering the entire neuraxis is a primitive network of mesenchymal cells known as the meninx primitiva. The meninx follows the folds that appear during development of the brain, filling the interhemispheric fissure that forms bet...

The brain, spinal cord, and skin are all derived from the embryonic ectoderm; this common derivation leads to a high association between central nervous system dysraphic malformations and abnormalities of the overlying skin. A myelomeningocele is an obvious open malformation, the identification of which is not usually difficult. However, the relationship between congenital spinal cord malformat...

Introduction: Vascular abnormalities are relatively uncommon lesions, but head and neck is a common region for vascular malformation which is classified as benign tumors. In this paper, the authors report a rare presentation of vascular malformation in the tongue and its managements. Case Report: An 18 months 2 old child presented with a giant mass of tongue which caused functional and aesth...

Angiogenic factor with G-patch and FHA domain 1 (AGGF1) is a novel angiogenic factor that was first described in Klippel-Trenaunay syndrome, a congenital vascular disease associated with capillary and venous malformations. AGGF1, similar to vascular endothelial growth factor (VEGF), has been shown to promote strong angiogenesis in chick embryos in vivo. Blocking AGGF1 expression prevented vesse...
