RESUMO
El síndrome de Netherton (SN) es una enfermedad autosómica recesiva, muy poco frecuente, que se caracteriza por la presencia de eritrodermia ictiosiforme congènita, anomalías capilares y manifestaciones atópicas. Este síndrome es consecuencia de una mutación recesiva en el gen SPINK5. Las manifestaciones del síndrome de SN varían considerablemente entre las personas que lo padecen. Aquí informamos el caso de un recién nacido que presentaba insuficiencia respiratoria grave, hipotermia y eritrodermia, al que se le diagnosticó SN, confirmado mediante pruebas genéticas moleculares.
Netherton syndrome (NS) is a rare, autosomal recessive disease characterized with congenital ichthyosiform erythroderma, hair abnormality and atopic manifestations. This syndrome is caused by recessive mutation in the SPINK5 gene. Disease manifestations vary considerably among NS individuals. We report a newborn presented with severe respiratory insufficiency, hypothermia and erythroderma, was diagnosed as having NS and confirmed with molecular genetic testing.

Las ictiosis hereditarias son un grupo de desórdenes mendelianos, con manifestaciones clínicas y alteraciones genéticas heterogéneas caracterizadas por la presencia de escamas y/o hiperqueratosis. Las ictiosis sindrómicas son aquellas en las que el defecto genético se manifiesta en la piel y también en otros órganos. Presentamos 7 pacientes con ictiosis sindrómicas: un síndrome IFAP (ictiosis folicular, atriquia, fotofobia), un síndrome de Conradi-Hünermann-Happle (CHH), dos síndromes de Netherton (SN), dos síndromes de Sjögren-Larsson (SSL) y un síndrome KID (queratitis, ictiosis, sordera). Se analizan las características clínicas y diagnósticas de nuestros pacientes (AU)
Inherited ichthyosis are a group of clinical and genetic heterogeneous disorders characterized by the presence of scales, hyperkeratosis or both. In syndromic ichthyosis, the genetic defect involves the skin and other organs. We present 7 patients with syndromic ichthyosis: a case of IFAP syndrome (ichthyosis follicularis with alopecia and photophobia), a case of Conradi-Hünermann-Happle (CHH) syndrome, two cases of Netherton syndrome, two cases of Sjögren-Larsson syndrome and a case of KID syndrome (keratitis, ichthyosis and deafness). We analyze the diagnostic and clinical features of our patients (AU)

Netherton syndrome is a rare autosomal recessive disease characterized by erythroderma, ichthyosis linearis circumflexa, atopy, failure to thrive and a specific hair shaft abnormality called trichorrhexis invaginata or bamboo hair, considered pathognomonic. We report the case of a 4-year-old boy with erythroderma since birth, growth deficit and chronic diarrhea. Trichoscopy was used to visualize typical bamboo and "golf tee" hair and of key importance to diagnose Netherton syndrome. We suggest the use of this procedure in all children diagnosed with erythroderma.
