PAEZ, E et al. Autosomal recessive lamellar ichthyosis: review of the literature and clinical case. Rev. argent. dermatol. [online]. 2020, vol.101, n.1, pp.101-110. ISSN 1851-300X.

The autosomal recessive congenital ichthyosis (ARCI) is a rare worldwide condition with an incidence of (1: 300,000 births), characterized by disorders of keratinization, among its variants encompass the non-syndromic forms of ichthyosis, such as laminar ichthyosis (IL) , congenital ichthyosiform erythroderma (EIC) and currently include harlequin ichthyosis, self-healing colodion baby, acral self-healing colodion baby and ichthyosis in swimsuits. From a genetic point of view, they’re heterogeneous, originated by a mutation in the gene of transglutaminase 1 and associated with TGM1, ALOXE3, ALOX12B, NIPAL4, CYP4F22 and ABCA12. Clinically, ichthyosis is mainly characterized by thick skin, adherent lamellar scales with deep clefts. The aim of this work is to review the current knowledge in the field of ICAR, including clinical, histological, ultrastructural, genetic-molecular and therapeutic aspects as well as its clinical management.

Keywords : Autosomal recessive congenital Ichthyosis; keratinization disorders; transglutaminase mutation 1.
