The epidermal nevus syndrome (ENS) is a rare neurocutaneous disease characterized by extensive epidermal nevi and a wide variety of abnormalities involving brain, eyes, and skeleton. Neurological symptoms in ENS include seizures, paresis, and mental retardation and are usually ascribed to hemimegalencephaly and various migration disorders. It was suggested that in some patients neurological symptoms might be secondary to vascular abnormalities. We report a case of a patient with diagnosed ENS without any primary CNS lesions, who developed paraplegia resulting from spinal cord hemorrhage. The patient presented many vascular and skeletal anomalies.

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.

Sebaceous lesions are associated with two syndromes with widespread multisystem disorders and tumors. Linear sebaceous nevus syndrome has been traditionally known as the triad of sebaceous nevus of Jadassohn, seizures, and mental retardation. This syndrome encompasses a much broader spectrum of multisystem disorders, which is explored below. Muir-Torre syndrome is described as the presence of sebaceous tumors or keratoacanthomas with an underlying visceral malignancy. It is caused by mutations in DNA mismatch repair genes. We discuss its relationship with Lynch syndrome and suggest a comprehensive algorithm on how to screen patients with sebaceous neoplasms for Muire-Torre syndrome. We also provide suggested intensive cancer screening guidelines based on recommendations for patients with Lynch syndrome that may also be of value for patients with Muir-Torre syndrome.

Epidermal nevus syndrome is a clinically variable and genetically heterogeneous group of mosaic conditions characterized by the concurrence of extensive epidermal nevus with additional cutaneous and extracutaneous manifestations. This term groups together well-characterized clinical entities, as well as dozens of apparently unique associations, which need further delineation. We report on a 23-year-old woman presenting the previously undescribed combination of widespread eccrine proliferation, multiple facial and oral pox-like lesions, gingival synechiae, blepharophimosis, body asymmetry, and mental retardation. The patient has a healthy monozygotic twin. The eccrine proliferation is intermingled with areas of unaffected skin with a linear/segmental distribution on the limbs. The clinical presentation of such a complex phenotype fits well with the genetic mosaicism theory. The histologic findings, consisting of proliferation of immature to well-formed eccrine duct-like structures located in the deep dermis and interspersed with an abundant fibrous stroma constituted of horizontally oriented collagen fibers, seem a possible hallmark of this condition.

The epidermal nevus syndrome (ENS) is an uncommon neurocutaneous disorder in which epidermal nevi are found in association with congenital abnormalities of the brain, eye, and/or skeleton. The association of epidermal nevi and neurologic abnormalities was comprehensively described by Schimmelpenning in 1957. Pavone et al. (1991) identified a homogeneous variant of ENS with hemimegalencephaly, gyral malformation, mental retardation, seizures and facial hemihypertrophy. A 13-year-old boy with the neurologic variant of ENS with hemimegalencephaly, facial asymmetry, febrile seizures and mental retardation is reported. Additionally, we performed a literature review using the search terms "epidermal nevus syndrome" and "hemimegalencephaly", including secondary sources of data such as reference lists of articles reviewed. We found 57 previously reported cases with the hemimegalencephalic variant of epidermal nevus syndrome, in which the most frequent associated features are severe epilepsy, in about half of cases with neonatal onset, mental retardation/developmental delay, ocular/visual involvement, and facial abnormalities.

A 12-year-old girl presented with extensive epidermal nevi, new onset seizures, mental retardation, and oral and ocular abnormalities. We briefly review the case and epidermal nevus syndrome (ENS), which is characterized by epidermal nevi occurring in conjunction with neurologic, ocular, skeletal, and/or other system involvement.

Epidermal nevus syndromes are a group of rare multiorgan disorders. Schimmelpenning syndrome is a clinical variant of epidermal nevus syndromes. This congenital syndrome is characterized by the existence of nevus sebaceous and usually accompanied by abnormalities of the eyes, skeletal, cardiovascular, and central nervous systems. A 2-year-old girl presented with large, hairless, yellowish-brown plaques on the scalp and face along with multiple brownish-black verrucose plaques and brownish-black macules on almost all parts of the body. The skin-colored verrucose tumors were also found on the lips and around the mouth. Histopathological examination of the lesion on the forehead revealed hyperkeratosis, acanthosis, and sebaceous gland hyperplasia supporting the diagnosis of nevus sebaceous, while histopathological examination of the lesions on the lips and abdomen demonstrated hyperkeratosis, acanthosis, and papillomatosis consistent with verrucous epidermal nevus. The pediatrician suspected that the patient had mental retardation; however, there were no neurological, cardiac, skeletal, nor ophthalmologic abnormalities. The lesions on the lips and around the mouth were excised, and it demonstrated a good result. To conclude, epidermal nevus syndrome (e.g., Schimmelpenning syndrome) should be considered in children born with nevus sebaceous.
