sjogren-larsson syndrome (sls) is an inherited autosomal recessive neurocutaneous disorder with congenital ichthyosis, spastic diplegia or quadriplegia and mental retardation. we report a case of sjogren-larsson syndrome with clinical profile (mental retardation, ichthyosis, spastic diplegia) and mri findings such as seen in multiple sclerosis (ms). so this rare syndrome can be another differen...

harlequin ichthyosis is a rare and the most severe form of congenital ichthyosis. although prenatal diagnosis is difficult for this disorder, recently, this obstacle has markedly improved with the use of dna-based prenatal diagnosis. here in, we presented a neonate with harlequin ichthyosis born by assisted reproductive technology (art). in this case, the diagnosis of harlequin ichthyosis was n...

Severe vitamin D deficiency and rickets are highly prevalent among children with congenital ichthyosis. We report an incidental observation of a dramatic and excellent clinical response with regard to skin scaling and stiffness in children with congenital ichthyosis after short-term high-dose vitamin D supplementation that has not been previously described. Seven children with congenital ichthy...

Harlequin ichthyosis is one of the most severe congenital skin cornification disorders with an incidence rate of about 1 in 300000 births and characteristic clinical features. We report two cases of harlequin ichthyosis (HI) or harlequin fetus (HF), which were products of consanguineous union. Clinical examination showed typical features of harlequin ichthyosis, with the presence of plaques wit...

Harlequin ichthyosis is a rare congenital ichthyosis classified under the category of Autosomal Recessive Congenital Ichthyoses, which also include lamellar ichthyosis and congenital ichthyosiform erythroderma. It is caused by functional null mutations in the ABCA12 gene, a keratinocyte lipid transporter associated with lamellar granule formation. Patients have a classic clinical presentation a...

Hereditary ichthyoses are due to mutations on one or both alleles of more than 30 different genes, mainly expressed in the upper epidermis. Syndromic as well as nonsyndromic forms of ichthyosis exist. Irrespective of etiology, virtually all types of ichthyosis exhibit a defective epidermal barrier that constitutes the driving force for hyperkeratosis, skin scaling, and inflammation. In nonsyndr...

IN the complete form of this familial syndrome males suffer from corneal dystrophy, congenital ichthyosis (ichthyosis simplex), and allergic manifestations such as asthma and hay fever. The complete syndrome was noted in two patients. Other male members had corneal dystrophy and allergy, corneal dystrophy and ichthyosis, ichthyosis alone, ichthyosis and allergy, or asthma (Fig. 1). Except for t...

Congenital ichthyosis is often associated with typical neonatal phenotypes, "Collodion baby" and "Harlequin foetus", later transforming into severe lamellar or erythrodermic ichthyosis. However, in a minority of cases the skin condition will improve spontaneously after birth, although slight scaling, xerosis, hypohidrosis and keratoderma usually persist. Some of these patients will eventually b...
