Ichthyosis are a heterogeneous group of Hereditary and acquired disorders keratinization characterized by the presence visible scales on skin surface. The word is derived from Greek root for fish – icthys. There two major types ichthyosis that Congenital Acquired. vulgaris one among congenital most common with an estimated incidence rate 1 in 250 births, onset early childhood fine, whitish whic...

Autosomal recessive congenital ichthyosis (ARCI) includes a wide range of ichthyosis phenotypes, including harlequin ichthyosis, lamellar ichthyosis (LI), congenital ichthyosiform erythroderma (CIE), and self-improving collodion ichthyosis (SICI) (1, 2). To date, 9 causative genes for ARCI have been identified (1, 2). ALOXE3 is a causative gene in LI as well as CIE, and it encodes the eLOX-3 li...

The term autosomal recessive congenital ichthyosis (ARCI) refers to a group of rare disorders of keratinization classified as nonsyndromic forms of ichthyosis. This group was traditionally divided into lamellar ichthyosis (LI) and congenital ichthyosiform erythroderma (CIE) but today it also includes harlequin ichthyosis, self-healing collodion baby, acral self-healing collodion baby, and bathi...

Harlequin ichthyosis is a rare and exceedingly severe form of congenital ichthyosis with an incidence of approximately 1 in 300,000 births. These patients are at a high risk for neonatalinfection and septicemia. Most affected infants die within the  first days or weeks of life.We report a male baby born with harlequin ichthyosis. There is limited information regarding the course and...

INTRODUCTION Placental sulphatase deficiency/congenital ichthyosis is an X-linked inborn error of metabolism which was first described in 1969 by France and Liggins.1 It is an enzymatic defect affecting steroid metabolism, clinically manifested by diminished oestrogen production during fetal life and by congenital ichthyosis post-natally. This disorder has a reported incidence of between 1: 6,0...

Congenital ichthyosis encompasses a large group of keratinizing disorders with widespread scaling and a variable degree of erythema. Little is known about the quality of life in children with congenital ichthyosis and the impact of the disease on their family. Fifteen children aged 5-16 years with lamellar ichthyosis, Netherton's syndrome, epidermolytic hyperkeratosis or Harlequin ichthyosis, w...

Collodion baby (CB) is normally diagnosed at the time of birth and refers to a newborn infant that is delivered with a lambskin-like membrane encompassing the total body surface. CB is not a specific disease entity, but is a common phenotype in conditions like harlequin ichthyosis, lamellar ichthyosis, nonbullous congenital ichthyosiform erythroderma, and trichothiodystrophy. We report a CB tha...

Congenital ichthyosis is a group (almost 100 clinical variants) of rare genetic skin diseases caused by pathogenic changes in more than 50 genes. Clinical features ichthyosis, regardless its genotype, are dry skin, peeling, hyperkeratosis frequently accompanied with erythroderma. These patients have extremely low quality life due to appearance, discomfort itching and functional limitations (pai...
