Notable milestones in the treatment of vascular lesions have been achieved over the past century. Many cutaneous vascular lesions can be successfully treated with lightbased devices. In this review, we will discuss the treatment of port-wine birthmarks, lymphatic malformations, infantile hemangiomas, rosacea, venous lakes, pyogenic granulomas, cherry angiomas, and angiofibromas using lasers, total reflection amplification of spontaneous emission of radiation, intense pulsed light, and photodynamic therapy. In addition, for several of these diagnoses, we will review medical therapies that can be combined with light-based devices to provide enhanced results...

Vascular anomalies represent a spectrum of structural disorders and inborn errors of vascular morphogenesis, which may affect the entire arterial and venous vascular tree. They are divided into two major categories: tumors, which exhibit endothelial hyperplasia and malformations, which have normal endothelial turnover unless disturbed. Depending on their nature and complexity they can range from a simple "birthmark" to life-threatening entities. The relatively low incidence (4-10%) of vascular anomalies among the general population combined with the fact that their management often falls within the purview of several different medical and surgical specialties, has traditionally resulted in insufficient expertise in the management of these conditions...

BACKGROUND: Cutaneous lesions are very common in neonates. Although a number of studies have reported on their incidence, very little is known about the factors that influence them. We set out to investigate a large population of neonates with the aims of achieving an overall picture of neonatal skin manifestations, and examining their relationships with various maternal, neonatal and perinatal factors. METHODS: This study was conducted on neonates born at the Department of Obstetrics and Gynaecology at the University of Szeged between June 2013 and July 2015...

Sturge-Weber Syndrome (SWS) is a neurocutaneous disease with clinical manifestations including ocular (glaucoma), cutaneous (port-wine birthmark), neurologic (seizures), and vascular problems. Molecular mechanisms of SWS pathogenesis are initiated by the somatic mutation in GNAQ. Therefore, no definite treatments exist for SWS and treatment options only mitigate the intensity of its clinical manifestations. Biological assay design for drug discovery against this syndrome demands comprehensive knowledge on mechanisms which are involved in its pathogenesis...

Vascular anomalies constitute some of the most difficult diagnostic and therapeutic enigmas in the practice of medicine, ranging from an asymptomatic birthmark to life-threatening congestive heart failure. Hemangiolymphangiomas (HLA) are extremely rare vascular malformations of both lymphatic and blood vessels in which 80-90% are diagnosed during the first 2 years of life. Though rare, these vascular malformations have promising clinical outcomes. We report a case of a 28-year-old male who presented with a neck mass of unknown etiology...

Gene expression was examined in hemangiomas (HA), benign, birthmark-like tumors occurring in infancy, and confirmed in HA-derived endothelial cells (HDEC), for which cell proliferation and apoptosis were also assessed. Protein and mRNA accumulation of Rho-associated protein kinase (ROCK), vascular endothelial growth factor (VEGF), Ki-67 and proliferating cell nuclear antigen was significantly higher in proliferating phase HAs than in involuting phase HAs. In contrast, p53 and caspase-3 exhibited higher levels of accumulation in involuting than proliferating HAs...

Over the past decade, I have been amazed at the growth in the field of vascular anomalies. The recognition of vascular birthmarks as a defined area of medicine is a relatively recent event. The International Society for the Study of Vascular Anomalies (ISSVA) was founded by Drs John Mulliken and Anthony Young in the late 1970s. Mulliken and Glowacki's sentinel 1982 paper on the biologic classification of vascular anomalies further established the field, by providing clarity of nomenclature and unifying concepts that had previously been lacking...

Sturge-Weber syndrome (SWS) is a vascular neurocutaneous disorder that results from a somatic mosaic mutation in GNAQ, which is also responsible for isolated port-wine birthmarks. Infants with SWS are born with a cutaneous capillary malformation (port-wine birthmark) of the forehead or upper eyelid which can signal an increased risk of brain and/or eye involvement prior to the onset of specific symptoms. This symptom-free interval represents a time when a targeted intervention could help to minimize the neurological and ophthalmologic manifestations of the disorder...

Here, we review our current knowledge on the etiology and treatment of port-wine stain (PWS) birthmarks. Current treatment options have significant limitations in terms of efficacy. With the combination of 1) a suitable preclinical microvascular model, 2) laser speckle imaging (LSI) to evaluate blood-flow dynamics, and 3) a longitudinal experimental design, rapid preclinical assessment of new phototherapies can be translated from the lab to the clinic. The combination of photodynamic therapy (PDT) and pulsed-dye laser (PDL) irradiation achieves a synergistic effect that reduces the required radiant exposures of the individual phototherapies to achieve persistent vascular shutdown...

BACKGROUND: Twins have a higher-than-expected risk of infantile hemangiomas (IHs), but the exact reasons for this association are not clear. Comparing concordant and discordant twin pairs might help elucidate these factors and yield more information about IH risk factors. METHODS: A prospective cohort study of twin pairs from 12 pediatric dermatology centers in the United States, Canada, Argentina, and Spain was conducted. Information regarding maternal pregnancy history, family history of vascular birthmarks, zygosity (if known), and pregnancy-related information was collected...

Common birthmarks can be an indicator of underlying genetic disease but are often overlooked. Mongolian blue spots (dermal melanocytosis) are usually localized and transient, but they can be extensive, permanent, and associated with extracutaneous abnormalities. Co-occurrence with vascular birthmarks defines a subtype of phakomatosis pigmentovascularis, a group of syndromes associated with neurovascular, ophthalmological, overgrowth, and malignant complications. Here, we discover that extensive dermal melanocytosis and phakomatosis pigmentovascularis are associated with activating mutations in GNA11 and GNAQ, genes that encode Gα subunits of heterotrimeric G proteins...

Sturge-Weber syndrome is a vascular malformation syndrome consisting of a facial port-wine birthmark associated with malformed leptomeningeal blood vessels and a choroid "angioma" of the eye. It is a rare neurocutaneous disorder that occurs sporadically, is not inherited, and is caused by a somatic mosaic mutation in GNAQ. In patients with Sturge-Weber syndrome, brain involvement typically presents in infancy with seizures, strokes, and stroke-like episodes, and a range of neurologic impairments. Standard treatment includes laser therapy for the birthmark, control of glaucoma through eyedrops or surgery, and the use of anticonvulsants...

PHACE(S) syndrome is a neurocutaneous disorder of unknown etiology. The acronym refers to the commonest features of PHACE: posterior fossa malformations, large facial hemangiomas, cerebral arterial anomalies, cardiovascular anomalies, and eye anomalies. When ventral developmental defects such as sternal clefting or supraumbilical raphe occur, the PHACES acronym may be used. The hallmark feature of PHACE is the presence of one or more large facial infantile hemangiomas that occupy at least one facial segment...

Birthmarks can frequently be seen in newborn babies, but their etiopathogenesis is often unclear. These lesions can be divided into three groups: vascular birthmarks, pigmented birthmarks, and birthmarks resulting in abnormal development. Some birthmarks may require further analysis and clinical follow-up in order to rule out underlying defects, malignant potential, or correlation with syndromic diseases. Presented here is the case of a newborn baby with two simultaneous birthmarks: an adnexal polyp and a nevus anemicus...

BACKGROUND: The incidence of localized intravascular coagulopathy (LIC) in venous malformations varies with lesion size and location, as well as the presence of palpable phleboliths. The development of LIC can cause pain and hemorrhage and can progress to disseminated intravascular coagulopathy (DIC) and thromboembolic disease resulting in death in some cases. Early recognition of LIC can relieve symptoms and prevent progression to life-threatening complications. OBJECTIVE: The aim of this work was to identify MRI features of venous malformation associated with LIC...

Vascular anomalies represent a spectrum of disorders from a simple "birthmark" to life- threatening entities. Incorrect nomenclature and misdiagnoses are commonly experienced by patients with these anomalies. Accurate diagnosis is crucial for appropriate evaluation and management, often requiring multidisciplinary specialists. Classification schemes provide a consistent terminology and serve as a guide for pathologists, clinicians, and researchers. One of the goals of the International Society for the Study of Vascular Anomalies (ISSVA) is to achieve a uniform classification...

Clinical history, physical examination, evolution and imaging findings (Colour Doppler sonography, MRI if available) are of pivotal importance in the diagnostic pathway of an infantile vascular anomaly. Histopathology with specific stains and markers is contributive in difficult cases. Differentiation between vascular tumors (hemangioma) and vascular malformations is now well known and integrated into the ISSVA classification. We report here a 6-months-old boy, who presented with a localized cutaneous and expansive vascular birthmark in the left cheek and developed bleedings at the age of 18 months...

Infantile hemangiomas are a common vascular birthmark with heterogeneous presentations and unique growth characteristics with early rapid growth and eventual self-involution. Hemangiomas that develop around the eye have the potential for inducing amblyopia by several mechanisms and may eventually result in permanent visual impairment in otherwise healthy infants. Segmental periocular hemangiomas carry the additional risk of associated structural anomalies and PHACE syndrome. In recent years, the treatment of periocular hemangiomas has been revolutionized by the serendipitous discovery of the effectiveness of beta-blockers (systemic and topical), with most experts viewing these as first-line therapies...
