Report of a case of linear nevus sebaceous of Jadassohn with the classical syndrome: 1) the facial linear nevus; 2) focal convulsions and 3) mental retardation. Skin biopsy didn't show proliferation of the sebaceous glands showing to be an early case. Computerized tomography showed slight cortico-subcortical atrophies, in contrast with the intensity of the mental retardation and focal crisis. Convulsions were controlled by several drug associations.

The sebaceous nevus syndrome is sometimes associated with hemimegalencephaly and a group of related abnormalities including ipsilateral gyral malformation, mental retardation, seizures, especially infantile spasms, and facial hemihypertrophy. This combination has been described as the "neurological variant of epidermal nevus syndrome." Other brain malformations have been reported only rarely. We report on a child with a subtle sebaceous nevus associated with hemimegalencephaly who also had agenesis of the corpus callosum and Dandy-Walker malformation.

We report a case of linear nevus sebaceous syndrome with seizure, mental retardation, and hemiparesis. Magnetic resonance imaging (MRI) clearly demonstrated associated brain malformations of unilateral megalencephaly with cortical dysplasia and white matter change ipsilateral to the sebaceous nevi of the face and neck. Although magnetic resonance angiography (MRA) demonstrated only distortion of the main cerebral arteries without any occlusive or dysplastic findings, single photon emission computed tomography (SPECT) using [123I]N-Isopropyl-p-iodoamphetamine (IMP) revealed hypoperfusion in the affected cerebral hemisphere.

Epidermal nevus syndrome (ENS) is a congenital neurocutaneous disorder characterized by linear nevus with a significant involvement of the nervous, ophthalmological and skeletal systems. Clinical manifestations of ENS include neurological features such as mental retardation, seizures, and movement disorders which are caused by a wide range of neuropathological lesions. We describe three patients with ENS, all of whom had in addition to the characteristic features of ENS intracranial and/or intraspinal lipomas. In one patient the lipoma extended from the thoracal vertebra 8 to the 4th ventricle; in the second patient it was localized on T9, and in the third patient an intracranial lipoma was located at the right cerebellopontine angle. The intraspinal lipomas caused a significant spastic movement disorder. So far, CNS lipomas have not been described as typical neuropathological findings in ENS. The differential diagnosis to encephalocraniocutaneous lipomatosis with the typical finding of CNS lipoma is discussed.

We describe an 8-year-old boy with Rubinstein-Taybi syndrome, a multiple congenital anomaly/mental retardation syndrome characterized by broad thumbs and great toes, peculiar facies, and mental retardation caused by mutations in the transcriptional coactivator CREB binding protein (CBP). He had on his right side yellowish papular lesions organized in narrow bands according to Blaschko lines, later confirmed by histology as an epidermal nevus. Epidermal nevus syndrome has been ruled out because the patient failed to meet the criteria for inclusion under this designation. This association may be coincidental.

The report focuses on a rare variant form of epidermal nevus syndrome (ENS) (Schimmelpenning-Feuerstein-Mims syndrome) describing lesions involving the skin, eyes, skeleton, heart and brain in an 11-year-old boy. Despite his evident brain pathology, the boy lacks neurological symptoms and mental retardation. We describe his unusual MRI appearances and radiographic skeletal findings. To our knowledge this is the first report of ENS with lymphoedema occurring together in the same individual.

Linear sebaceous nevus syndrome (LSNS) is a rare neurocutaneous syndrome that is associated with seizures and mental retardation. The cortical abnormalities that are associated with this syndrome include focal cortical dysplasia, partial hemimegalencephaly and holohemispheric hemimegalencephaly. Few reports have addressed the utility of cortical resections for epilepsy treatment in the setting of LSNS. We report 3 children with this syndrome who underwent extensive cortical resections and experienced significant improvement in seizure frequency. Our results support the utility of extensive cortical resections for children with this condition.

Epidermal nevus syndrome is a kind of neurocutaneous syndrome that is associated with epidermal nevus and a variety of congenital CNS disorders. Clinical presentations include seizures, paresis, mental retardation, and developmental delay. We report three cases with MR imaging and magnetoencephalography findings; one patient underwent ictal and interictal single photon emission CT. Both structural and functional imaging studies indicated that the frontal lobes had lesser involvement or were intact. One patient underwent hemispherectomy because of the medically intractable seizure. He remained seizure free with topiramate monotherapy.

Gustav Schimmelpenning was born in 1928 in Oldenburg (Germany). From 1971 until 1994 he was head of the Department of Psychiatry at the University of Kiel. In 1957, while training in neurology and psychiatry, he comprehensively described a case of sebaceous nevus involving the head, with ipsilateral ocular lesions including coloboma of the upper lid, increased density of cranial bones, epileptic seizures and mental retardation. He concluded that this combination of anomalies represented a new 'phacomatosis'. Subsequently this phenotype was reported by other authors under many different names, such as 'Schimmelpenning syndrome', 'Feuerstein-Mims syndrome', 'Schimmelpenning-Feuerstein-Mims syndrome', 'epidermal nevus syndrome', 'Solomon syndrome', 'linear sebaceous nevus syndrome', 'organoid nevus phacomatosis', or 'Jadassohn nevus phacomatosis'. As a consequence of this confusing terminology, Schimmelpenning syndrome even has two different OMIM entries (no. 163200 and no. 165630). The term 'Schimmelpenning syndrome' is both historically justified and practically sufficient to distinguish this phenotype from other epidermal nevus syndromes.

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.
