I report 2 unusual cases of Proteus syndrome that support the concept of somatic mosaicism. In one patient, a huge connective tissue nevus covered the chest and abdomen and hyperostoses of the calvaria were observed. In the other patient, linear verrucous epidermal nevi, epibulbar dermoids, and hyperostoses were found. No enlargement of the limbs or digits occurred and the plantar surfaces of the feet were normal. Selective aspects of Proteus syndrome not previously reviewed are also presented including: uncommon neoplasms; pulmonary and renal abnormalities; brain malformations; facial phenotype associated with seizures and severe mental deficiency; and types of abnormal growth in the craniofacial skeleton.

"Epidermal nevus syndrome" ("ENS") is a neurocutaneous disorder in which epidermal nevi are associated with other abnormalities, most commonly of the skeletal and central nervous systems. We present two cases of epidermal nevus syndrome (ENS) with very different clinical findings. The first case is a newborn with multiple linear epidermal nevi of the trunk and limbs, and several other anomalies, including bony duplications of the lower limbs and hypoplastic left heart syndrome. The second patient, a 6-year-old boy, has a linear nevus sebaceous of the scalp with severe CNS involvement, including generalized seizures, moderate mental retardation, microcephaly, and a left hemiparesis. He also has genitourinary, cardiac, and skeletal defects. These two patients exhibit several abnormalities not previously recognized and illustrate the wide clinical spectrum of "epidermal nevus syndrome." We present a review of the clinical findings in 74 cases of "ENS." Correlation was noted between the presence of skin lesions located on the head and CNS involvement. The wide clinical spectrum of "ENS" as illustrated by these two patients suggests that "ENS" is a causally heterogeneous group of disorders.

We report the development of intractable epilepsy in 3 patients treated with irradiation to "strawberry" scalp nevi in infancy. Low-dose radiation was used (12 and 13 Gy in 2 of the patients). The clinical evolution suggested a recognizable and distinctive postradiation syndrome. There was concordance between the site of radiation as shown by localized alopecia, the clinical features of the partial seizures, and electrographic abnormalities. The clinical picture was unlike delayed cerebral radiation necrosis of adulthood, which is not thought to occur at doses below 50 Gy, in 2-Gy fractions. Neurological deficits were not progressive and in 2 patients there was no evidence of parenchymal injury on cranial magnetic resonance imaging scanning. These differences suggest pathogenetic differences to cerebral radiation injury of adulthood, probably relating to the interaction between nervous system development, individual susceptibility, and the low doses of radiation employed.

A patient with Sturge-Weber syndrome without the characteristic facial nevus presented with focal seizures which were difficult to control and borderline mental level. CT disclosed calcification in the right occipital zone. A marked decrease of the regional cerebral blood flow that extended beyond the abnormalities depicted on CT was seen by SPECT. Venous magnetic resonance (MR) angiography revealed reduction of the superficial cortical veins and prominent deep collateral venous system in the same side of the cerebral lesion. Cranial MR imaging with Gd-DTPA demonstrated the pial angioma.

The epidermal nevus syndrome (ENS) is an unusual neurocutaneous disorder consisting of the combination of an epidermal nevus and a central nervous system (CNS), ophthalmological, and/or skeletal abnormality. The study reports four new patients with ENS. Each had a confirmatory biopsy of the epidermal nevus, abnormal neurological examination findings, and documented CNS anatomical studies by imaging or autopsy. The paper also reviews the literature in English to determine neurological abnormalities found in skin-biopsy-proven cases of ENS. Hemi-atrophy, hemimegalencephaly, migrational abnormalities and vascular anomalies were found to be the most frequent intracranial abnormalities associated with ENS. Seizures and/or disabling moderate to severe developmental delays were present in a majority of patients. Seizure onset during the neonatal period or early infancy was associated with major hemispheric malformations. Neuroectodermal-derived ocular lesions were often bilateral. No consistent relation between laterality of the nevus and laterality of CNS abnormalities was found, supporting the gene mosaicism theory of pathogenesis.

We report the case of a 39-year-old para-4 gravida-4 who received polychemotherapy 5-fluorouracil 600 mg/m2, cyclophosphamide 600 mg/m2 and epirubicin 50 mg/m2 for invasive breast cancer (pT2N2Mo) with extensive metastatic involvement of all 23 axillary lymph nodes removed at 29 gestational weeks. Soon after the second course of chemotherapy at 35 weeks, she developed two eclamptic tonic-clonic seizures which were treated by antihypertensive and anticonvulsive drugs and delivery of a healthy infant, 1650 g (< 10th percentile) by cesarean section. That this patient indeed suffered from eclampsia was supported by the findings of transient postpartum severe hypertension (peak 170/110 mmHg), proteinuria (peak 3.2 g/24 h), incomplete features of the HELLP syndrome (thrombocytopenia 81,000/mm3, haptoglobin < 10 mg/dl) and of DIC, and by the results of cerebral CT scanning showing two 1-cm ischemic lesions. Since the detrimental effect of antineoplastic agents on the rapidly proliferating trophoblast is well known and as abnormal placental function, such as in triploidy, trisomy or hydatiform mole, has been associated with an increased risk for preeclampsia/eclampsia, a possible causal relationship between polychemotherapy and the subsequent development of this rare disorder is suggested.

A 9-year-old girl was diagnosed as having a linear sebaceous nevus syndrome (LSNS). The nevus sebaceus was located on the face, and the girl also had nevoid hypertrichosis on the neck, sensorineural deafness, partial anodontia, blocked tear ducts, labiopalatoschisis, and an area of micropolygyria in the left encephalic (cerebral) hemisphere. Electroencephalographic alterations were detected, but they were not accompanied by a history of seizures; furthermore, the child was not mentally retarded. This phenotypic pattern of LSNS is unusual for the rarity of associated abnormalities.

The authors report the coexistence of vascular nevi (hemangiomas and arteriovenous malformations (AVMs) of the skin) with AVMs and venous malformations of the brain in male siblings from two related but nonconsanguineous families of three generations. The proband, his siblings, parents, aunts, uncles, and cousins were examined, underwent magnetic resonance (MR) imaging and MR angiography, and when appropriate, cerebral angiography. A father had vascular nevi and a mother, his sister, had an azygos anterior cerebral artery. No other cutaneous or cerebrovascular malformations were present in the parents. Each of the two families had two boys and one girl, 9 to 18 years of age. All the children had vascular nevi and all of the boys had coexisting cerebrovascular malformations: AVMs in three, and a venous malformation in another. One boy had three cerebral AVMs. Two boys had a cerebral hemorrhage, and one also had focal motor seizures. The skin lesions were not those of the Sturge-Weber-Dimitri, Rendu-Osler-Weber, or Wybum-Mason syndromes. The association of cutaneous and cerebrovascular malformations was seen only in males in these families. but females have also been reported in the literature. The results obtained in these families and three other families reported from Western and Central Europe indicate that the association of cerebral and cutaneous vascular hamartomas constitutes a distinct, hereditary clinicopathological entity with autosomal dominant inheritance and variable penetrance. The clinical manifestations of this syndrome are visible, painful vascular nevi, epilepsy, cerebral hemorrhage, and focal neurological deficits. The preponderance of male patients with the full expression of the syndrome suggests a possible hormonal influence on the expression of the gene.

Neurocutaneous melanosis is a syndrome consisting of cutaneous nevi and melanocytosis of the leptomeninges. Over a 5-year period (1989-1994) we evaluated with MR imaging the central nervous system of five children with a confirmed histologic diagnosis of neurocutaneous melanosis. The children ranged in age from 7 to 10 years and consisted of two girls and three boys. They all had multiple pigmented skin lesions (cutaneous nevi) and presented with seizures, signs of raised intracranial pressure, cranial nerve palsies and/or myelopathy. The MR studies were performed with T1-weighted, T2-weighted and T1-weighted post-gadolinium images of the brain in addition to T1-weighted post-gadolinium images of the entire spine. The MR findings in all the children consisted of marked, diffuse enhancement of thickened leptomeninges surrounding the brain and spinal cord which was only demonstrated on the post-gadolinium T1-weighted images and mild to moderate hydrocephalus. We present our MR findings and compare these findings with other imaging findings in the literature. Our findings represent part of a spectrum of imaging abnormalities seen in patients with neurocutaneous melanosis.

A term male neonate had an uncommon congenital vascular disorder of the skin covering the whole body and extremities. These skin lesions were characterized by mottling and persistent telangiectasia. A skin biopsy showed nevus vascularis reticularis which was recognized as cutis marmorata telangiectatica congenita. In addition to the cutaneous involvement, the patient also had fetal ascites, pleural effusion, patent ductus arteriosus, glaucoma, retinal detachment in the left eye, and telangiectasia in the right eye. Neonatal focal seizure developed and expired on the 34th day of life. The cerebral image studies suggested vascular anomalies with secondary cerebral parenchymal damage. Cutis marmorata telangiectatica congenita may be solitary but is frequently associated with other developmental defects. However, the specific findings of cerebral and ophthalmic lesions in our case were rather unusual.
