The aim of this study was to present the case of the child with linear nevus sebaceous syndrome (LNSS) and hemimegalencephaly, diagnosed in neonatal period. It is one of the five epidermal nevus syndromes. Etiology of this multiorgan disease is still unknown. Most often LNSS consists of central nervous system, skeletal and ocular abnormalities. In present case different epileptic non-responsive seizures began in second week of life. In image exams hemimegalencephaly was found. EEG pattern showed generally discharges. The fits responded to vigabatrin. Psychomotor retardation was observed. Sometimes the skin lesion may be only manifestation of the syndrome. It is very important to perform early image and EEG examinations in LNSS.

Sturge - Weber syndrome (SWS) is a rare disorder that occur with a frequency of approximately 1 per 50,0001. It isa neurocutaneous syndrome, characterized by a facial vascular birthmark and neurological abnormalities. The hallmark is intracranial vascular angioma, most often involving the occipital and posterior parietal lobes, but it can also affect the other cortical regions. An ipsilateral facial cutaneous vascular malformation (port wine nevus)usually affects the upper face. Other clinical findings associated with SWS are seizures, glaucoma, hemiparesis,mental retardation and delayed developmental milestones. This article reports a case of 8 years old boy who presented with weakness of right half of body since birth, mental retardation and delayed developmental milestones. Clinical examination revealed deep purple nevus on left lower face, and less power of left upper & lower limbs.X-ray skull showed calcification. C.T. Scan of brain revealed curvilinear calcification with focal atrophy.

The sebaceous nevus syndrome describes the rare association of a sebaceous nevus with systemic features such as mental retardation, seizures and colobomas (among others). It is thought to be a cutaneous mosaic inherited as a paradominant trait. Three cases are provided illustrating the intraoral manifestations of the syndrome. The first histological comparison of contiguous mucosal and cutaneous lesions is provided. We also describe the possible association of SFM syndrome with a benign fibrous histiocytic lesion of the mandible. This and other mandibular tumors associated with the sebaceous nevus syndrome may have significant implications for patients. Awareness of the potential presence or development of significant intraoral lesions in association with the sebaceous nevus syndrome is important for those involved in the care of patients with this syndrome.

Sturge-Weber syndrome is a neurocutaneous syndrome with a facial port-wine nevus and neurologic features, typically including seizures and hemiparesis. Glaucoma may also occur. MRI features include leptomeningeal angiomatosis, cortical and pial calcifications, and angiomatous change of the choroid plexus. We reviewed a subset of patients with Sturge-Weber syndrome with the rare finding of deep venous occlusion, and present such a case, unusual by comparison to previously reported cases of Sturge-Weber syndrome with deep venous occlusion. Six previously reported cases were reviewed. All cases presented with seizures; five of six had evidence of leptomeningeal angiomatosis; half had cerebral hemiatrophy. This report presents a unique case lacking clinical seizures, but with a port-wine stain and congenital glaucoma. This patient lacked the radiologic findings of leptomeningeal angiomatosis and hemicerebral atrophy, but demonstrated deep venous occlusion with frontal venous collaterals. There is a wide spectrum of findings in Sturge-Weber syndrome. The lack of seizures and angiomatosis in this case are likely "true-true" and related. The case illustrates the unusual finding of deep venous occlusion in Sturge-Weber syndrome occurring without leptomeningeal angiomatosis. Additionally, it demonstrates that although the initial evaluation is normal, patients may later manifest clinical characteristics of Sturge-Weber syndrome.

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder characterized by venous malformations usually affecting the skin and the gastrointestinal tract. These skin haemangiomas are present at birth and deteriorate as the body grows, causing primarily cosmetic problems. The haemangiomas of the gastrointestinal tract may appear later in life and may bleed, causing chronic anaemia, or may present with severe complications such as rupture, intestinal torsion, and intussusception. Other organs may also be involved. This article describes a 13-year-old boy with multiple haemangiomas of the skin, the mucous membranes, and the gastrointestinal tract, which caused anaemia and ileoileic intussusception. In this patient, the nervous system was significantly affected with a haemangioma of the left occipital lobe, with complications of stroke. He also had multiple paravertebral heamangiomas, which caused pressure signs and symptoms. This boy suffered from complex partial and generalized seizures and cerebral palsy. Multiple skeletal anomalies were also present from birth. In the relevant literature, this is the first case of BRBNS with simultaneous neurological and skeletal involvement. Such cases should be recognized early, as they can lead to serious multiple health problems and handicaps.

In 1947 the term phakomatosis pigmentovascularis (PPV) was coined to represent the association of widespread, aberrant, and persistent nevus flammeus and pigmentary abnormalities. Four types of PPV have been recognized with type II (nevus flammeus and Mongolian spots) being the most common. Most early cases were of Asian or African descent. Many cases were subsequently associated with Sturge-Weber (S-W) and Klippel-Trenaunay (K-T) syndromes. Almost no literature reports have appeared in the genetic or dysmorphology literature! We present six cases of PPV in which five were either African, Asian or Hispanic, and five of six had an admixture of K-T and S-W. Four had macrocephaly, and one had microcephaly. Four had CNS abnormalities (three with hydrocephalus, one with Arnold-Chiari and one with polymicrogyria), three had mental retardation, and one had seizures. One each had thumb hypoplasia, hydronephrosis, glaucoma, coronal synostosis, and 3-4 finger syndactyly. It is our suspicion and hypothesis that in the presence of persistent, extensive and aberrant Mongolian spots, vascular abnormalities as are seen in K-T and S-W carry a worse prognosis. This may be particularly true either of children of Asian, Hispanic or African heritage or any individuals from darker pigmented skin groups.

Encephalocraniocutaneous lipomatosis (ECCL) is a sporadically occurring neurocutaneous disorder characterized by ocular anomalies, mainly choristomas; by skin lesions consisting of hairless fatty tissue nevi (nevus psiloliparus), focal dermal hypoplasia, alopecia, and periocular skin tags; and by CNS anomalies, including intracranial and spinal lipomas and often mental retardation and seizures. Here, we report on three boys with ECCL with typical abnormalities of the eyes, skin and brain and, in addition, coarctation of the aorta. All three children developed multiple cystic bone lesions, which progressively spread throughout the skeleton in Patient 1 and was shown histologically to be non-ossifying fibromas in Patient 2. We hypothesize that ECCL may be caused by mosaicism for a mutated gene involved in benign mesenchymal tumors and in vasculogenesis.

Linear nevus sebaceous syndrome is reported to occur in as many as 1 in 1000 live births, and is hypothesized to result from genetic mosaicism involving a lethal autosomal-dominant gene. The terms "epidermal nevus syndrome" and "linear nevus sebaceous syndrome" are often used interchangeably, although linear nevus sebaceous syndrome more strictly applies to patients with a typical midline nevus, and epidermal nevus syndrome is a more inclusive term that includes all varieties of epidermal nevi. Linear nevus sebaceous syndrome encompasses a broad spectrum of abnormalities that may affect every organ system, including the central nervous system. In these cases, seizures and mental retardation are the main manifestations. Many other organ systems were also reported to be involved in this syndrome, including the cardiovascular, skeletal, ophthalmologic, and urogenital systems, among others. Although linear nevus sebaceous syndrome occurs at a relatively high frequency and may affect different organ systems, many physicians are unaware of the syndrome, which may delay diagnosis and treatment. We present two cases of linear nevus sebaceous syndrome, and we describe their initial presentation and subsequent evolution, incorporating a review of the current literature in this field.

A 5-year-old Mexican girl had a bilateral, systematized epidermal nevus of a non-epidermolytic, non-organoid type covering large parts of her body with the exception of the scalp. Clinically, this nevus was of a soft, velvety type showing affinity to the large body folds. Histopathological examination revealed orthohyperkeratosis and papillomatosis without granular degeneration and without any abnormality of adnexal structures. During infancy she developed seizures, and subsequently a delayed mental development was noted. Computer tomography of the brain revealed cortical and subcortical atrophy, a subdural hygroma in the left frontoparietotemporal region, and hypoplasia of corpus callosum. Molecular analysis of a biopsy specimen obtained from the epidermal nevus revealed a heterozygous R248C hotspot mutation in FGFR3, whereas in normal skin the FGFR3 wild-type allele was exclusively found. The R248C mutation was also present in DNA extracted from blood leukocytes. Because FGFR3 is involved in the development of the central nervous system, the clinical and genetic findings of this case indicate a widespread mosaicism of the FGFR3 mutation. This unusual mosaic phenotype may represent a distinct entity within the group of epidermal nevus syndromes.
