Abstract
INTRODUCTION Capillary malformations such as benign hereditary telangiectasia are a familial affection, of dominant autosomal transmission, characterized by the progressive development of cutaneous telangiectasia during childhood. The association with cutaneous vascular, arteriovenous or lymphatic malformations is exceptional and has only recently been described. CASE REPORT A 5 year-old girl presented with widespread erythematous, predominantly telangiectasic, congenital and acquired macules when she was one year-old. Her history was marked by right temporal cerebral hemorrhage at the age of 4, revealing a right temporal cavernoma-like vascular malformation. The familial history of telangiectasic macules and clinical and histological examination led to the diagnosis of benign hereditary telangiectasia. DISCUSSION This case report raises doubt on the exclusively cutaneous nature of benign hereditary telangiectasic-type capillary malformations. Moreover, it illustrates the possibility of a particular clinical form of this affection, associating classical telangiectasia and post-wine stain-type macules. The recent localization of the locus implied in this affection in 5q14 in the same chromosomic space as the CMC1 locus incriminated in familial capillary malformations, suggests that these two affections are in fact phenotype variations of a single and same clinical entity.

Abstract
INTRODUCTION Ito hypomelanosis-type pigmentary mosaicism is characterized by congenital pigmentation disorders along Blaschko's lines. We report a case of Ito-type pigmentary mosaicism associated with a congenital growth hormone deficiency having revealed trisomy 20 mosaicism. OBSERVATION A 4 year-old boy presented with congenital pigmentation disorders. His history was marked by: inter-uterine delayed growth of unknown etiology, a dysmorphic syndrome, psychomotor retardation with speech problems, right cryptorchidia and an isolated, idiopathic, congenital growth hormone deficiency that had been treated with recombinant somatropine since the age of three. The clinical examination revealed alternating hypo and hyper-pigmented maculae with linear distribution on the limbs and in "twirls" on the trunk following Blaschko's lines. The blood karyotype was normal, the karyotype on fibroblasts of hypopigmented skin revealed trisomy 20 mosaicism. DISCUSSION The occurrence of pigmentary mosaicism related to trisomy 20 mosaicism is exceptional. The combination of Ito hypomelanosis-type pigmentary mosaicism and delayed growth due to growth hormone deficiency has never been reported before. Our observation, unusual because of such an association, raises the question of the eventual existence of associated genes located on the chromosome 20 implied in the secretion of growth hormone and/or melanogenesis. It also underlines the interest of conducting cytogenic explorations on fibroblasts of damaged skin in the case of Ito-type pigmentary mosaicism, even if the blood karyotype is normal or in the absence of a patent phenotype abnormality.

Abstract
BACKGROUND Psoriasis is a common inflammatory skin disease characterized by uncontrolled proliferation of keratinocytes and recruitment of T lymphocytes into the skin. The possible role of human endogenous retroviruses (HERVs) in the induction of psoriasis has been suggested, based upon the previous observations of retrovirus-like particles in psoriasis from skin lesional plaques, urine and stimulated lymphocytes. OBJECTIVES To investigate the expression of HERV-E transmembrane envelope glycoprotein (HERV-E env) in normal, psoriatic and atopic human skin, and to examine the influence of ultraviolet (UV) B irradiation on HERV-E env expression in normal human epidermal keratinocytes. METHODS The analysis was performed on both skin biopsies and organotypic skin cultures using immunofluorescence and Western immunoblotting. UVB irradiation (312 nm) of cultured normal human keratinocytes was performed using a dose of 30 mJ cm(-2). RESULTS Positive staining was observed in most of the psoriatic and atopic skin samples, whereas only 15% of the normal skin samples were faintly positive. In addition, the pattern of expression of HERV-E env differed markedly in psoriasis vs. atopy. By Western blotting analysis, two main proteins of 54 and 57 kDa were detected in extracts of normal skin, normal keratinocyte cultures and reconstructed epidermis from psoriatic and normal punch biopsies. An increased level of expression of these proteins was noted in extracts from psoriatic vs. normal reconstructed epidermis. The overexpression of the 57-kDa protein in normal human cultured keratinocytes was dramatically reduced by UVB irradiation. CONCLUSIONS These data suggest for the first time that HERV-E env is expressed in normal and pathological human skin. Further studies are now required to elucidate the role of such viral proteins in the pathogenesis of psoriasis.

Abstract
INTRODUCTION Familial dyskeratotic comedones is a rare affection of autosomal transmission and characterized by pseudo-comedone papules predominantly on the limbs. We report a new familial case characterized by its clinical and histological profile. CASE REPORT A 6 year-old boy presented with a papular, pseudo-comedone eruption that had appeared shortly after birth and had progressively extended symmetrically to both legs. The child's father complained of a similar eruption since childhood. Histological examination of the papules revealed a pseudo-follicular invagination, obstructed by keratin and associated with areas of focal dyskeratosis. Treatment with local retinoids was ineffective. DISCUSSION Since it is often asymptomatic, the prevalence of dyskeratosis comedones is probably underestimated. A review of the literature on the preceding observations is presented. The dermatites that would represent differential diagnoses because of the presence of comedone-like lesions and/or histological dyskeratosis are discussed.

Abstract
INTRODUCTION alpha-Interferon is associated with numerous cutaneous side effects, but the accurate incidence of these complications is not clearly known. OBJECTIVES A prospective study was designed to evaluate the incidence and clinical pattern of cutaneous side effects in a cohort of patients receiving adjuvant therapy with low-dose interferon for malignant melanoma. MATERIAL AND METHODS A cohort of 33 patients with stage IIA and IIB melanoma treated with low-dose alpha-interferon (3 MIU 3 times a week for 18 months) were prospectively enrolled in a single-center study. The patients responded to a questionnaire on their medical history and were systematically examined for any cutaneous lesions before treatment and every 3 months afterwards. RESULTS 29/33 patients (87%) experienced 1 or more cutaneous side effects. The most frequent was hair loss and occurred in 16 cases (48.4%). Hair discoloration was noted in 6 cases (18%). Eczematous reactions at injection sites or at remote sites were observed in 13 patients (39%). Pruritus occurred in 10 cases (30%). Xerostomia, Raynaud's phenomenon or livedo reticularis were observed in 10 patients, associated with an increase in circulating autoantibody titer in 2 cases. Some rare side effects were observed: urticaria (1 case) or angioedema (1 case), worsening of preexisting seborrheic dermatitis (3 cases), herpetic recurrence (2 cases), pityriasis versicolor (1 case), worsening of recurrent buccal aphthous ulcer (1 case) and vitiligo (1 case). CONCLUSION Cutaneous adverse events during adjuvant immunotherapy of melanoma with low-dose alpha-interferon seem to be frequent but do not result in treatment discontinuation. A good awareness of these side effects may be useful for a more accurate survey and clinical management of patients receiving this treatment.

Abstract
UNLABELLED UNDERESTIMATED SIDE EFFECTS: Skin reactions to interferon (INF) treatment are uncommon in the larger series in the literature and are usually considered to be minor. They account for 5 to 12% of adverse effects to IFN and are encountered increasingly in patients with active chronic hepatitis C. Reactions may be local, occurring exclusively at the site of injection, or general. REPORTED EFFECTS AND TREATMENTS We reviewed the literature on local skin reactions at the site of injection of the different interferons to study the underlying pathophysiological mechanisms and management schemes used. TWO TYPES OF REACTIONS Local skin reactions can be divided into two types depending on the potential gravity and management. Minor reactions (transient erythema, eczema, depilation) have few clinical or therapeutic implications. More serious reactions, necrosis, vasculitis or injection can be potentially severe and require definitive interruption of treatment. PREVENTION Preventive measures include careful education concerning self-injections using proper asepsia, variation of injection sites, and self-assessment of persistent skin reactions.

Abstract
The uniqueness of a surface density of sources localized inside a spatial region R and producing a given electric potential distribution in its boundary B0 is revisited. The situation in which R is filled with various subregions, each one having a definite constant value for the electric conductivity is considered. It is argued that the knowledge of the potential in all B0 fully determines the surface-located sources for a general class of surfaces supporting them and also a wide type of those sources. The class of surfaces can be defined as a union of an arbitrary but finite number of open or closed surfaces. The only restriction upon them is that no one of the closed surfaces contains inside it another (nesting) of the closed or open ones. The types of sources are surface charge densities and double layer (dipolar) densities for the open surfaces and more restrictively, only surface charge densities for the closed ones. A two-dimensional analytically solvable example illustrating the drastic appearance of uniqueness after arbitrarily small holes are opened in nested surfaces is discussed.

Abstract
BACKGROUND Porphyria cutanea tarda (PCT) is associated in most cases with iron overload, which may participate in decreased activity of uroporphyrinogen decarboxylase in the liver. The aetiology of this iron overload remains unknown; however, it has been demonstrated that mutations of HFE, the genetic haemochromatosis gene, might be present in a significant proportion of Anglo-Saxon and Italian patients. Furthermore, transferrin receptor polymorphism may influence the affinity of this receptor to its ligand with a subsequent increase of cellular iron absorption and storage. OBJECTIVES To evaluate the incidence and spectrum of HFE mutations and the relative frequency of the two main alleles of transferrin receptor in patients with PCT originating from southern France, and to evaluate the relationship of these genetic data with iron status, and with hepatitis B and C and human immunodeficiency virus (HIV) infections. METHODS Thirty-six consecutive patients with either sporadic or familial PCT were prospectively included between 1997 and 2000. Search for the presence of the three main mutations of the HFE gene and identification of the transferrin receptor alleles were performed using polymerase chain reaction followed by enzymatic digestion. Iron parameters and viral status for hepatitis B and C viruses and HIV were determined. RESULTS Seven patients (19%) showed heterozygous C282Y mutation, but no C282Y homozygote was present; five patients (14%) carried homozygous H63D mutation, while eight (22%) were heterozygous for this mutation. One patient was heterozygous for the S65C mutation (3%). Iron parameters demonstrated overload in all patients, without a clear difference between patients with and without deleterious mutations of the HFE gene. Infection by hepatitis C virus was documented in 20 patients (56%), and was significantly less frequent in patients with deleterious HFE mutations. The profile of transferrin receptor alleles in PCT patients did not show significant variation compared with the general population. CONCLUSIONS This study confirms the high frequency of HFE mutations in patients with PCT and supports the hypothesis that HFE gene abnormalities might play a significant part in the PCT pathomechanism, probably through iron overload; by contrast, transferrin receptor polymorphisms do not appear to play a significant part in iron overload in PCT.
