ABSTRACT

Resumen Las ictiosis congénitas autosómicas recesivas (ICAR) son poco frecuentes a nivel mundial con una incidencia de 1:300,000 nacimientos, se caracterizan por trastornos de la queratinización, entre sus variantes engloban las formas no sindrómicas de ictiosis, como la ictiosis laminar (IL), la eritrodermiaictiosiforme congénita (EIC) y actualmente se incluyen la ictiosis arlequín, el bebé colodión autorresolutivo, el bebé colodión autorresolutivoacral y la ictiosis en traje de baño. Desde el punto de vista genético son heterogéneas, originadas por una mutación en el gen de la transglutaminasa 1 y se las haasociado a TGM1, ALOXE3, ALOX12B, NIPAL4, CYP4F22 y ABCA12. Clínicamente, la ictiosis se caracteriza principalmente por piel gruesa, escamas laminares adherentes con hendiduras profundas. En este trabajo pretende revisar los conocimientos actuales en el campo de las ICAR, incluyendo aspectos clínicos, histológicos, ultraestructurales, genético-moleculares, tratamiento,y también su manejo clínico.


Abstract 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.

ABSTRACT

AbstractSelf-healing collodion baby is a well-established subtype of this condition. We examined a male newborn, who was covered by a collodion membrane. The shed membrane was examined with scanning electron microscopy. The outer surface showed a very compact keratin without the normal elimination of corneocytes. The lateral view of the specimen revealed a very thick, horny layer. The inner surface showed the structure of lower corneocytes with polygonal contour. With higher magnifications villous projections were seen in the cell membrane.

ABSTRACT

El término bebé colodión se refiere a una condición transitoria del recién nacido que consiste en la presencia de una membrana translúcida y adherente que recubre casi completamente la superficie corporal. Constituye una manifestación inicial común a varias entidades; las más frecuentes son la ictiosis lamelar y la eritrodermia ictiosiforme congénita no ampollar. A continuación presentamos una serie de 14 pacientes que nacieron como bebé colodión y una revisión actualizada de la literatura.

ABSTRACT

Feto arlequim é uma variante grave da ictiose congenita, uma herança autossômica recessiva que causa alteração da queratinização da pele, que incide em cerca de 1/100.000 nascimentos e está geralmente associada a consaguinidade dos pais. Manifesta-se ao nascimento como uma pele espessada que evolui para rachaduras generalizadas, comprometendo as suas funções básicas e predispondo a infecções. Relata-se o caso de um RN do sexo feminino, cujos pais não referem nenhum grau de parentesco. A mesma foi mantida em isolamento em incubadora, mas feleceu no nono dia de vida por insuficiência respiratória restritiva.


Harlequin fetus is a variant of severe congenital ichthyosis, an autosomal recessive heredity make change in the keratinization of skin, which appear around 1/100.000 births and is usually associated with consaguineus parents. At birth it seems like a thicken skin that develops into widespread cracks, affecting its basics functions and predisposes to infections. We report the case of a female newborn, whose parents don’t mention any degree of kinship. The baby stood on isolation in incubator, but died at ninth day of life from restrictive respiratory failure.

ABSTRACT

Os autores relatam um caso de uma criança do sexo feminino com ictose congênita, de pais näo consangüíneos, diagnosticado no Hospital Universitário da UFSC. A paciente apresentava descamaçäo cutânea generalizada e palmo-plantar, ectrópio, eclábio e distrofia ungueais em membros superiores, além de alteraçöes histopatologicas que indicaram o diagnóstico de ictiose lamelar recessiva. O tratamento foi realizado com cremes hidratantes e queratolíticos. Os autores apresentam comentários sobre o diagnóstico diferencial e tratamento das formas mais comuns desta patologia
