Collodion Baby with TGM1 gene mutation

چکیده
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 that was brought to our department and later diagnosed to have TGM1 gene c.984+1G>A mutation. However, it could not be ascertained whether the infant had lamellar ichthyosis or congenital ichthyosiform erythroderma (both having the same mutation). The infant was lost to follow-up.

Collodion babies are newborns encased in a glistening membrane that cracks in a characteristic manner within 48 h and desquamates in large lamellae after a few days. Most collodion babies later develop one of the several types of autosomal recessive congenital ichthyoses (ARCI), such as lamellar ichthyosis (LI) or congenital ichthyosiform erythroderma; however, about 10% heal spontaneously (1)....

Background: Collodion baby is a rare condition (i.e., 1:300000 birth), which is referred to a neonate covered with a tight and shiny membrane desquamating within two weeks. This condition takes place as a result of the epidermal cornification disorder. Given the impairment of the skin barrier function, these neonates are at the risk of several complications, including hypernatremic dehydration,...

BACKGROUND Bathing suit ichthyosis (BSI) and self-improving collodion ichthyosis (SICI) are 2 minor variants of generalized autosomal recessive congenital ichthyosis. Bathing suit ichthyosis is characterized by scaling of the skin in a bathing suit pattern, mainly limited to the trunk, whereas SICI is characterized by complete disappearance of the skin lesions. OBSERVATIONS We report genotypi...
متن کاملAutosomal recessive congenital ichthyosis.
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...

The ichthyoses comprise a group of keratinisation disorders characterised by generalised scaling of the skin. Lamellar ichthyosis (LI) is usually manifested at birth as a collodion baby with ectropion/eclabion. Collodion membrane means encased in a tight shiny covering. It is characterised afterwards by non-bullous scaling of the whole integument with variable erythroderma. LI is a major subtyp...
