Unilateral nevoid telangiectasia and chronic liver disease. Report of a case and review of the literature

Unilateral nevoid telangiectasia was observed on the back of the left hand and wrist in a 19-year old man with chronic liver disease and portal hypertension. Moreover, abnormalities of the elastic fibers of the skin were found. Examination of the liver biopsy showed extensive portal fibrosis with many dilated blood vessels. No usual cause of juvenile cirrhosis was detected. In the comment, the authors suggest that unilateral nevoid telangiectasia and liver disease could be manifestations of a disease involving skin and liver vessels, as in hereditary hemorrhagic telangiectasia.

Focal choroidal calcification

Localized choroidal calcification was detected clinically in two otherwise healthy men. The lesions showed typical features of choroidal nevi. One patient exhibited features suggesting a drusen overlying the nevus. Echography detected choroidal calcification in both cases. A-scan echography revealed a highly reflective choroidal mass attenuating the ultrasound beam. B-scan ultrasonography revealed a dense choroidal mass attenuating the ultrasound beam with focal echoes remaining at low sensitivity. Orbital radiographic and CT scan examination confirmed the echographic findings.

[Linear epidermal nevus with multiple malformations. (author's transl)]

We report about a 12 year old boy who was born with a linear epidermal nevus. This nevus extended from the umbilicus strictly along the midline to the symphysis and continued on the right leg caudally to the medial brim of the foot and the first and second toe. Changes of bone structure are seen at-x-ray examination of the right hip and leg. Vascular dysplasia with arteriovenous shunts and spinal angiomas were found by angiography in the vascular bed of the left iliac artery. The length of the legs differed due to hyperplasia of the left lower extremity and both feet resembled the "Friedreich-foot".

Urological implications of the beckwith-wiedemann syndrome

A significant number of children with the Beckwith-Wiedemann syndrome are prone to the development of nephroblastomas and adrenal carcinomas. Renomegaly, a prolonged tubular blush on excretory urography similar to that of medullary sponge kidney, and previously undescribed caliceal diverticula may be observed. Diligent followup is mandatory to detect early neoplasia. Suggestions are detailed based on reported case management.

Nevus comedonicus with epidermolytic hyperkeratosis. A report of four cases

Four patients with nevus comedonicus (NC) and the histological changes of epidermolytic hyperkeratosis (EH) are described. The relationship between NC and other epidermal nevi in which EH may occur is further emphasized by this finding.

Diffuse iris nevus manifested by unilateral open angle glaucoma

Uncontrolled unilateral glaucoma developed in the right eye of a 24-year-old woman. It was caused by the diffuse growth of a nonpigmented nevus of the iris into the anterior chamber angle. Histologically, the nonpigmented nevus cells in the angle were distinguishable from a proliferation of corneal endothelium. Clinically, there was no heterochromia, and a tumor was not suspected as the cause of the glaucoma.

Facial hemihypertrophy associated with nevus unius lateris syndrome

A review of the clinical characteristics and etiologic theories of nevus unius lateris and associated facial hemihypertrophy is presented. A case report with significant medical and dental findings is discussed in light of the significant social and physical impairment resulting from oral hemihypertrophy and other physical deformities.

Extensive nevus comedonicus

A 19-year-old woman had an extensive nevus comedonicus affecting the left arm, trunk, and leg. Her condition was complicated by episodes of recurrent cyst formation and secondary infection. These were reduced in extent and frequency during 14 months of treatment with a combined progesterone-estrogen contraceptive preparation, and the appearance of the lesions affecting the leg was improved. The clinical features, histogenesis, histology, and treatment of nevus comedonicus are discussed.

B-K mole syndrome. Cutaneous and ocular malignant melanoma

A 51-year-old white man had the B-K mole syndrome (multiple large atypical cutaneous nevi of the upper part of the trunk and extremities, inherited as an autosomal dominant trait, and thought to be more susceptible to malignant transformation), so named after two patients in whom the syndrome was first observed. Two cutaneous malignant melanomas (thigh and back) and an ocular malignant melanoma (ciliary body and iris) simultaneously developed. Patients with B-K mole syndrome have been known to have a very high risk for the development of cutaneous melanoma (including multiple primary cutaneous melanomas) and multiple primary malignancies. There may be a propensity in these patients for development of ocular melanomas.

[Congenital homolateral epidermal hyperplasia and hypoplastic hemidysplasia (splitting of the Solomon's syndrome) (author's transl)]

The observation of a 16-year-old girl born with an ectromelia and an ipsilateral inflammatory verrucous epidermal nevus led us to a synthetic study of 17 similar cases already published since 1927: all these cases concern female patients and are characterized by a unilateral hypoplastic dysplasia, most often of limbs, and inflammatory epidermal hyperplastic lesions described as ichthyosiform, psoriasiform or verrucous, usually distributed on the same side on the skin overlying the dysplastic body areas. The skin lesions may be partly regressive after birth and their histological features are suggestive of inflammatory linear verrucous epidermal nevus (I. L. V. E. N.). These associations may be representative of a special form of Solomon's syndrome whose heterogeneity has be recently emphasized. We propose to subdivide it in 3 forms: the epidermal nevus syndrome (Solomon's syndrome)--the organoid nevus syndrome (Schimmelpenning's syndrome)--the I. L. V. E. N. syndrome, probably X-linked dominant inherited (lethal for hemizygous males), associated with ipsilateral hypoplastic body lesions and, however less frequently than in the epidermal nevus syndrome, with ocular and nervous abnormalities. The distribution of cutaneous lesions has some similarities with the pattern of skin symptoms of X-linked dominant traits such as chondrodysplasia punctata, focal dermal hypoplasia or incontinentia pigmenti. The most typical feature of this syndrome is the strong inflammatory aspect of the epidermal nevus erroneously described in previous cases as unilateral psoriasis or ichthyosiform erythroderma.

Electron microscopy in iris nevus syndrome

In a patient with the clinical features of the iris nevus syndrome who was treated for glaucoma a cataract developed later. The sector of iris removed during cataract extraction was examined by electron microscopy and was found to be covered by ectopic corneal endothelium with an underlying atypical Descemet's membrane. Abnormalities in the iris included aggregates of melanophagic cells in the anterior stroma and fibrosis in relation to the ectopic endothelium. These findings suggest that many of the iris abnormalities seen in this disorder occur on a reactive basis.

[Unilateral hypochromic verrucous epidermal nevus (author's transl)]

A case of unilateral hypochromic epidermal nevus is presented. A literature search and review of our own autopsy and ultrastructural studies did not permit the classification of this case to previously described genodermatoses. The possible origin of this congenital cutaneous malformation is discussed.
