Non-bullous congenital ichthyosiform erythroderma, with ocular albinism and Noonan syndrome.

A 21-year-old woman presented with non-bullous congenital ichthyosiform erythroderma; she was born a collodion baby. Associated features were ocular albinism, anterior segment dysgenesis of both eyes and Noonan syndrome. X-linked ichthyosis (steroid sulphatase deficiency) and X-linked ocular albinism have been mapped to the Xp22.3 region and cases have been reported with both conditions due to a partial short-arm deletion of the X chromosome. The ichthyosis and ocular albinism in the present case, however, are likely to be of the autosomal recessive type - a very rare association - and the combination with Noonan syndrome has not been reported previously.

Lipoxygenase-3 (ALOXE3) and 12(R)-lipoxygenase (ALOX12B) are mutated in non-bullous congenital ichthyosiform erythroderma (NCIE) linked to chromosome 17p13.1.

We report the identification of mutations in lipoxygenase-3 (ALOXE3) and 12(R)-lipoxygenase (ALOX12B) genes in non-bullous congenital ichthyosiform erythroderma (NCIE) linked to chromosome 17. Linkage disequilibrium analysis of six families affected by NCIE permitted us to reduce a recently reported interval of 8.4 cM on chromosome 17p13.1 to a 600 kb region around the marker D17S1796, which contains LOX genes. LOX products have long been implicated in skin disorders. Two point mutations and one deletion were found in ALOXE3 and three point mutations were found in ALOX12B in these consanguineous families from the Mediterranean basin. ALOXE3 and ALOX12B are two genes which are physically linked and functionally related. They are separated by 38 kb, have one more exon than the other LOX genes and are mainly expressed in epithelial cells including keratinocytes. Although the main substrate(s) of the two enzymes is (are) still unknown, the products of ALOX12B obtained in experimental systems have been demonstrated to be of R-chirality. It seems likely that the product of one of these enzymes may be the substrate of the other, and that they belong to the same metabolic pathway.

Selective involvement of keratins K1 and K10 in the cytoskeletal abnormality of epidermolytic hyperkeratosis (bullous congenital ichthyosiform erythroderma).

Aggregation of tonofilaments within epidermal keratinocytes is a characteristic histologic feature of epidermolytic hyperkeratosis including the generalized form known as bullous congenital ichthyosiform erythroderma. The histologic distribution and the keratin composition of the altered tonofilaments were investigated to determine whether the aggregation was specific to any particular keratin(s). Skin samples from seven patients and one mid-trimester fetus with generalized epidermolytic hyperkeratosis, and from one patient with a localized or "nevoid" form of epidermolytic hyperkeratosis, were analyzed by using various microscopical and immunocytochemical methods. A conjunctival sample and cultured epidermal keratinocytes from one patient with generalized epidermolytic hyperkeratosis were also examined by electron microscopy and immunocytochemistry. Ultrastructurally, tonofilament aggregates were distributed within the suprabasal stratified epithelial cell layers of the epidermis, of the infundibular part of outer root sheaths, and of the sebaceous ducts and sweat ducts, selectively following the known distribution pattern of keratins K1 and K10. The abnormal tonofilaments were not found in any other cutaneous epithelia, in conjunctival epithelium, or in cultured keratinocytes, where K1 and K10 are absent or only minimally expressed. Immunoelectron microscopy showed that among the keratins detected in suprabasal epidermolytic hyperkeratosis epidermis (K1/K5/K10/K14/K16), the aggregated tonofilaments predominantly expressed K1 and K10 rather than other keratins. These results suggest that the keratin filament abnormality in epidermolytic hyperkeratosis principally involves K1 and K10 and raise the question whether epidermolytic hyperkeratosis might be primarily a disorder of one or both of these keratins.

Structural, enzymatic and molecular studies in a series of nonbullous congenital ichthyosiform erythroderma patients.

Causative gene defects have not been demonstrated in the majority of nonbullous congenital ichthyosiform erythroderma (NBCIE) cases. The purpose of this study was to further elucidate the pathogenesis of NBCIE. Immunohistochemical and ultrastructural observations, transglutaminase activity assays and sequencing of TGM1 were performed in five patients from four NBCIE families. Transglutaminase 1 (TGase 1), involucrin and loricrin expression and in situ transglutaminase activity were present in all of the cases. Ultrastructurally, two cases out of five showed incomplete thickening of the cornified cell envelope (CCE) during keratinization and the other three exhibited abnormal lipid droplets in the cornified cells and malformed lamellar granules. No TGM1 mutation was found in any of the four families by direct sequence analysis. NBCIE cases with normal TGase 1 seemed to have two distinct patterns of abnormality, one with abnormal lipid droplets and malformed lamellar granules and the other with defective CCE formation.

A case of a Japanese neonate with congenital ichthyosiform erythroderma diagnosed as Netherton syndrome.

We report a 6-day-old Japanese girl showing generalized erythroderma accompanied by yellowish, exfoliative scaling that was accentuated on the face and scalp. Histological analysis showed psoriasiform dermatitis with acanthotic epidermis and premature shedding of the stratum corneum. Measurement of trypsin-like hydrolytic activity in SC showed six-fold greater activity compared with age-matched controls. DNA analysis revealed two mutations, 375delAT and 966insC, in exons 5 and 11, respectively, of the SPINK5 gene. Although at 4 weeks the child was still too young to display characteristic hair abnormalities or atopic diathesis, we diagnosed Netherton syndrome based on enzyme assay and DNA analysis.

A case of congenital reticular ichthyosiform erythroderma--ichthyosis 'en confettis'.

We describe the third case of congenital reticular ichthyosiform erythroderma (CRIE), a rare inherited keratinization disorder, the second with the peculiar reticulate skin pattern. The same case had been previously described and defined, for the clinical appearance, as ichthyosis 'en confettis'. An 18-year-old girl was born with the clinical features of an erythrodermic lamellar ichthyosis. Patches of normal skin enclosed by erythematous-ichthyotic skin in a reticular arrangement appeared on the trunk at the age of 10 years, and they enlarged slowly during 6 years. The treatment with etretinate, started 2 years ago, further increased this process. Another peculiar clinical feature is a remarkable hypertrichosis. At the ultrastructural level, perinuclear deposits of filamentous material in vacuolized keratinocytes of the upper epidermis, pathognomonic for CRIE, were demonstrated. This suggests that CRIE and ichthyosis 'en confettis' are the same disorder. In addition the peculiar clinical presentation of this rare genodermatosis develops only during late childhood and puberty. The identification of three sporadic cases only leaves the problem of inheritance still unsolved.

Congenital ichthyosiform erythroderma (C.I.E.)--ultrastructural evidences of abnormal stratum corneum retention.

Congenital ichthyosiform erythroderma (C.I.E.) is a skin disorder which has been considered as a hyperkinetic hyperkeratosis. This study was performed in order to demonstrate that C.I.E. pathogenesis includes both basal cell hyperplasia and abnormal stratum corneum retention. Electron microscopic studies were carried out on 5 cases of C.I.E., clinically and histopathologically diagnosed. The following pathological changes were found in stratum corneum and stratum granulosum: persistence of desmosomes in outer layers of stratum corneum, increased volume of intercorneocyte material, loss of lamellar pattern of Odland bodies, important variability in size and shape of keratohyaline granules, abnormal aggregation of tonofilaments. These constitute ultrastructural evidences of abnormal stratum corneum retention in C.I.E. pathogenesis.

Non-bullous ichthyosiform erythroderma associated with retinitis pigmentosa.

Non-bullous ichthyosiform erythroderma (NBIE) is an autosomal recessive condition characterized by generalized erythema and scaling. Two brothers with NBIE and retinitis pigmentosa are reported. One of them also had a marfanoid habitus, thoracic kyphosis, and arachnodactyly, and was heterozygous for alpha 1 antitrypsin deficiency. A third brother had skin involvement, but normal vision. Retinitis pigmentosa has been described in association with NBIE as part of Rud syndrome, which is no longer considered a separate entity. Major diagnostic features of Rud syndrome, such as hypogonadism, mental retardation, and epilepsy were absent in this family. The association of NBIE with retinitis pigmentosa in this family seems distinct from any previously described, currently recognized syndrome.

Prenatal diagnosis of congenital non-bullous ichthyosiform erythroderma (lamellar ichthyosis).

We report the first positive prenatal diagnosis of congenital non-bullous ichthyosiform erythroderma or lamellar ichthyosis. Fetal skin samples were obtained by fetoscopy at 21 weeks' gestation and examined by light and electron microscopy. Light microscopy revealed a thickened interfollicular epidermis with multiple layers of flattened cells and excessive keratinization of the epidermal lining of the follicular infundibulum. Electron microscopy of the thickened epidermis revealed granular cells that contained larger-than-normal keratohyalin granules and multiple layers of parakeratotic cornified cells. Although there was regional variation in the degree of interfollicular keratinization, follicles from all regions showed greater and more complete keratinization, indicating that they express the abnormality early enough in development to permit prenatal diagnosis at about 20 weeks' gestation.

Modified epidermal lipid composition in air-exposed culture of non-bullous congenital ichthyotic erythroderma (NBCIE) keratinocytes.

Emerged epidermal cultures on dead de-epidermized dermis (DED) constitute an excellent model for in vitro reproduction of dermatoses linked to a keratinocyte defect. We used such cultures for studies of non-bullous congenital ichthyotic erythroderma (NBCIE). Keratinocytes of normal and pathological origin were expanded in submerged cell cultures and frozen keratinocytes from the resulting cell bank were subsequently used for seeding on DED. Lipid extracts from 14 day emerged cell cultures were assayed qualitatively and quantitatively using thin layer chromatography and compared with the neutral and non-polar lipid profiles obtained from normal epidermis extracts and with those from the plantar stratum corneum of healthy donors and untreated NBCIE patients. The ichthyotic cultures were found to contain significantly elevated levels of n-alkanes, as were the lipid extracts from the patients' plantar horny layer. Our results demonstrate that a major marker of the NBCIE epidermis can be reproduced under the emerged culture conditions. They also indicate that the characteristic n-alkane increase in NBCIE is indeed endogenous and not merely related to possible contamination from topical treatments.

IgE heavy chain constant region genes in atopic dermatitis and senile erythroderma patients.

By Southern hybridization using a genomic DNA fragment carrying a human IgE heavy chain constant region gene (C epsilon) as a probe, we analyzed the organization of human C epsilon genes and their flanking regions in 23 atopic dermatitis and 6 senile erythroderma patients with elevated serum IgE levels, and 6 atopic dermatitis patients with normal IgE levels. On Bam HI, Hind III, and Eco RI digestions, we detected three hybridizable fragments containing three human C epsilon genes, C epsilon 1, C epsilon 2, and C epsilon 3, respectively, in all leukocyte DNAs. These fragments were almost identical in size among patients and healthy donors. Pst I digestion generated a genetic polymorphism. We, however, could find no correlation between this polymorphism and the disorders. It was concluded that among the patients and healthy donors, there was no marked difference in the organization of the functional C epsilon gene and its flanking region containing a class switch region. Our conclusion cannot rule out the presence of genetic abnormalities of this region in some atopic dermatitis patients which are not resolvable by our method. In the course of this study, we found a novel C epsilon-like gene in placenta DNA which differs from the three C epsilon genes commonly present in normal human DNA.

The CHILD syndrome. Congenital hemidysplasia with ichthyosiform erythroderma and limb defects.

The term CHILD syndrome is proposed as an acronym for congenital hemidysplasia with ichthyosiform erythroderma and limb defects. The syndrome is characterized by unilateral erythema and scaling, with a distinct demarcation in the middle of the trunk. The dermatosis is either present at birth or develops during the first weeks of life. Ipsilateral limb defects may vary from hypoplasia of some fingers to complete absence of an extremity. In addition, ipsilateral hypoplasia of other parts of the skeleton, as well as defects of the brain and the viscera are found. In some cases, ipsilateral punctate epiphyseal calcifications have been observed. Two further cases of this syndrome are reported, and a review of 18 previous observations is presented. The ratio of females to males is 19 : 1. Apparently, the CHILD syndrome is genetically determined. Arguments are presented in favor of the hypothesis that the conditions is due to an X-linked dominant gene lethal in hemizygous males.

Abnormal fibrous protein isolated from the stratum corneum of a patient with bullous congenital ichthyosiform erythroderma (BCIE).

The fibrous protein of stratum corneum was isolated from a patient with bullous congenital ichthyosiform erythroderma (BCIE), and its properties characterized using electron microscopy, amino acid analysis and SDS gel electrophoresis. Results were compared with the characteristics of the fibrous protein isolated from stratum corneum of normal controls. From 900 mg (dry weight) of stratum corneum, 68 mg of fibrous protein was obtained from the patient, while 178 mg was obtained from the normal control. Structural differences were observed with electron microscopy and chemical differences, were shown in the ratio of several amino acids. On SDS electrophoresis, the 55,000 dalton constituent of normal fibrous protein could not be identified in the fibrous protein from this patient. These results suggest that an alteration of the polypeptide composition of fibrous protein from this patient with BCIE occurred, and this alteration induced the morphological and clinical features of this dominant genetic keratinization disorder.

Omenn's syndrome and related combined immunodeficiency syndromes: diagnostic considerations in infants with persistent erythroderma and failure to thrive.

A 4-month-old male infant had a 2-month history of an exfoliative erythroderma and alopecia. Recurrent mucosal infections, diffuse lymphadenopathy, hepatosplenomegaly, lymphocytosis and eosinophilia, anemia, and failure to thrive later developed. Investigation revealed a combined immunodeficiency with T cells of an unusual phenotype in his peripheral blood, skin, and lymph nodes. Our patient's clinical manifestations most closely resemble Omenn's syndrome, a rare form of autosomal recessive combined immunodeficiency.

Leukemic erythroderma with elevated plasma IL-3 and hyperhistaminemia: in situ expression of IL-3 mRNA in leukemic cells.

We report a case of chronic myelogenous leukemia (CML) with pruritic erythroderma. Hyperhistaminemia, elevated level of plasma interleukin-3 (IL-3), and moderate basophilia were noted in this case. His skin manifestation was resistant to topical corticosteroid therapy and exacerbated in parallel with leukocyte count, plasma histamine and IL-3 levels. To identify localization and production of IL-3 in our case, we performed in situ hybridization on peripheral blood cells and skin biopsy specimen, and detected IL-3 mRNA in myelogenic cells in both specimens.

Atypical ichthyosiform erythroderma and congenital neurosensory deafness--a distinct syndrome.

A patient has been studied in whom an atypical ichthyosiform erythroderma was associated with congenital neurosensory deafness, vascularization of the corneas progressing to blindness, alopecia totalis, abnormalities of the teeth and nails, and postnatal growth deficiency. Twelve other patients with a similar pattern of malformation have been reported previously. This syndrome appears to represent a distinct disorder with a pattern of inheritance which is most likely autosomal recessive.

Plaquenil-induced erythroderma.

A patient who developed exfoliative erythroderma 11 days after the initiation of hydroxychloroquine treatment for psoriatic arthritis is presented. Our experience with her and the continued controversy regarding the incidence of adverse reactions in psoriatic patients to antimalarials prompted a detailed review of the literature. We conclude that the use of antimalarials in patients with psoriasis is associated with a high incidence of severe cutaneous adverse reactions. These medications should not be used in psoriatic patients if other less toxic, effective therapies are available.
