Incontinencia pigmenti. progresión clínica y diagnóstico de un caso / Incontinentia pigmenti. clinical progression and diagnosis of a case

Resumen La incontinencia pigmenti(IP) es una genodermatosis infrecuente ysistémica del neuroectodermo que involucra la piel, el sistema nervioso central, los ojos y los dientes, entre otros. Los signos clínicos dermatológicos constituyen el principal criterio diagnóstico, debido a que suelen ser los primeros en manifestarse. Se describen cuatro estadios característicos de la enfermedad según las lesiones cutáneas predominantes. No obstante, su pronóstico depende de los signos y síntomas extracutáneos. El diagnóstico se centra en criterios clínicos, histopatológicos y/o genéticos. Visto que no existe una terapéutica específica, la atención médica de esta enfermedad es multidisciplinaria y sintomática, y debe acompañarse del asesoramiento genético a los afectados y sus familiares. Presentamos el caso de una niña, nacida a término completo, quien presentó un cuadro clínico compatible con incontinencia pigmenti, del cual detallamos su progresión clínica, diagnóstico y seguimiento.

Abstract Incontinentiapigmenti is a rare and multisystemic,neuroectodermal genodermatosis that involves the skin, central nervous system, eyes and teeth, among others. Dermatological clinical signs are the main diagnostic criteria because they are usually the first to manifest. Four characteristic stages of the disease are described according to the predominant skin lesions. Nonetheless, prognosis depends on extracutaneous clinical signs and symptoms. Diagnosis is based on clinical, histopathological and/or genetic criteria. Considering there is no specific treatment available, the management of this disease is multidisciplinary and symptomatic, and must be accompanied by genetic counseling for those affected and their families. We present in a full-tern newborn femalethat presented with a clinical picture compatible with incontinentiapigmenti, and we will detail the clinical progression, diagnosis, and follow-up.

Incontinencia pigmentaria. Presentación de un caso / Incontinentia pigmenti. A case report

RESUMEN La incontinencia pigmentaria, también conocida como síndrome de Bloch-Sulzberger, es una rara genodermatosis ligada al cromosoma X, localizado en el Xq28. Afecta al sexo femenino y tiene diferentes expresiones clínicas en una misma familia. Es una enfermedad multisistémica, caracterizada por afectar de forma variable a los tejidos derivados del neuroectodermo, la piel, ojos, dientes y el sistema nervioso central. Las lesiones cutáneas son las más significativas desde el nacimiento, y la biopsia confirma el diagnóstico. Debido a la rareza de esta entidad, se presentó el caso de una lactante de un mes, con antecedente familiar de incontinencia pigmentaria, quien exhibía lesiones típicas en la piel desde la primera semana de vida, en diferentes fases, que siguen las líneas de Blaschko. Se constataron manifestaciones oculares y eosinofilia (AU).

ABSTRACT Pigmentary incontinence, also known as Bloch-Sulzberger syndrome, is a rare X chromosome-linked genodermatosis, located in Xq28. It affects the female sex and has different clinical manifestations in the same family. Ii is a multi-systemic disease characterized by affecting, in a variable way, the tissues derived from the neuroectoderm, the skin, the eyes, the teeth and the central nervous system. Skin lesions are the most significant ones since birth time, and skin biopsy confirms the diagnosis. Due to the rareness of this entity, we presented the case of a nursing female infant aged one month, with a family history of pigmentary incontinence, who presented typical lesions in the skin, since his first week of life, in different phases, following the lines of Blaschko. Ocular manifestations and eosinophilia were confirmed (AU).

Diagnóstico clínico de la incontinencia pigmentaria en dos neonatos con lesiones cutáneas vesículo-pustulosas / Clinical diagnosis of pigment incontinence in two neonates with vesicle-pustulous skin lesions

Introducción: La incontinencia pigmentaria es un trastorno neuroectodérmico sistémico que en el recién nacido se diagnostica por la presencia de lesiones cutáneas de tipo eritemato-vesiculosas o vesículo-pustulosas, con distribución según las líneas de Blaschko, asociadas a eosinofilia en muestra de sangre. Objetivo: Mostrar que es factible diagnosticar la incontinencia pigmentaria en el período neonatal, aún en casos esporádicos, mediante un adecuado ejercicio del método clínico. Presentación de los casos: Se trata de dos recién nacidas femeninas, nacidas a término, con peso adecuado para la edad gestacional y sin antecedentes pre- y perinatales de interés; la primera de las cuales se presenta al tercer día de nacida con lesiones en piel, de aspecto vesículo-pustuloso, que seguían el recorrido del nervio ciático poplíteo externo. El segundo caso se presenta al 11no día de nacida con lesiones de tipo vesículo-ampulosas, en región externa de los cuatro miembros, con mejoría a los 26 días de vida. En ambos casos se plantea el diagnóstico de incontinencia pigmentaria esporádica. Conclusiones: El diagnóstico de la incontinencia pigmentaria en el período neonatal constituye un reto, el cual es posible asumir si se lleva a cabo un adecuado uso del método clínico, con un minucioso diagnóstico diferencial. Para el diagnóstico, resulta útil establecer consenso a partir de un enfoque multidisciplinario(AU)

Introduction: Pigment incontinence is a systemic neuroectodermal disorder that in the newborn is diagnosed by the presence of skin lesions of erythematous-vesiculosus or vesicle-pustulous type, with distribution according to the Blaschko lines, associated with eosinophilia in the blood sample. Objective: Show that it is feasible to diagnose pigment incontinence in the neonatal period, even in sporadic cases, through proper performance of the clinical method. Presentation of cases: These are two female newborns, born full-term, with a suitable weight for gestational age and without a pre- and perinatal history of interest; the first case occurs on the third day of life, presenting skin lesions, vesicle-pustulous in appearance, which followed the path of the external popliteal sciatic nerve. The second case occurs on the 11th day of life with vesicle-ampulose lesions in the outer region of the four limbs, with improvement at 26 days of life. Diagnosis of sporadic pigment incontinence is stated in both cases. Conclusions: Diagnosing pigment incontinence in the neonatal period is a challenge, which can be assumed if proper use of the clinical method is carried out, with a thorough differential diagnosis(AU)

Introdução: Incontinência pigmentar é uma genodermatose incomum ligada ao X. É doença que afeta tecidos derivados do ectoderma e mesoderma com alterações sistêmicas múltiplas. As manifestações cutâneas são características da enfermidade e progridem de forma cronológica, assim como os achados histopatológicos. Objetivo: Essa é uma doença rara com manifestações cutâneas e extracutâneas, sendo as primeiras mais frequentes, cujo diagnóstico precoce e acompanhamento multidisciplinar são de suma importância. Descrição do caso: Relatamos dois casos de incontinência pigmentar em crianças do sexo feminino com manifestações clínicas diversas e diferentes critérios diagnósticos, de acordo com antecedentes familiares. Discussão: O acometimento cutâneo é uma característica marcante da incontinência pigmentar, o que torna a avaliação dermatológica o passo inicial na sua investigação. Cabe ao dermatologista se atentar para esse diagnóstico e encaminhar precocemente para avaliação multidisciplinar, a fim de minimizar possíveis complicações e promover qualidade de vida ao paciente.

Incontinencia pigmenti: a propósito de dos casos / Incontinentia pigmenti: report of two cases

La Incontinencia Pigmenti (IP) o síndrome de Bloch Sulzberger es un trastorno multisistémico neuroectodérmico, que afecta predominantemente al género femenino, cuya manifestación inicial incluye lesiones cutáneas que evolucionan por brotes. En ocasiones, se asocia a compromiso oftalmológico, neurológico y dentales parte del diagnóstico diferencial de lesiones ampollares en un neonato. Se presentan dos casos de IP diagnosticados en etapas cutáneas distintas, uno de ellos con compromiso neurológico.

Incontinentia Pigmenti (IP) or Bloch Sulzberger syndrome is a neuroectodermal multisystemic disorder, that predominantly affects women, whose initial manifestation includes skin lesions that evolve by outbreaks. Sometimes, is associated with ophthalmological, neurological and dental commitment. It is part of the differential diagnosis of bullous lesions in a newborn. We present 2 cases of IP diagnosed in different skin stages and one of them with neurological involvement.

Manifestações clínicas e desafios diagnósticos na Síndrome de incontinentia pigmenti / Multiple clinical manifestations and diagnostic challenges of incontinentia pigmenti Syndrome

A Síndrome de Incontinentia Pigmenti (Síndrome de Bloch-Sulzberger) é uma doença rara, ligada ao cromossomo X e envolve tecidos ectodérmicos de múltiplos órgãos. As manifestações oculares surgem ao nascimento ou após algumas semanas. O objetivo desse trabalho é relatar as características oftalmológicas, dermatológicas e os achados radiológicos de uma paciente com a Síndrome de Incontinentia Pigmenti. Trata-se de uma paciente do sexo feminino, 26 anos que procurou o serviço de Oftalmologia da Faculdade de Medicina do ABC com queixa de baixa de visão em ambos os olhos há 1 ano. Apresentava alterações retinianas importantes e lesões cutâneas e dentárias sugestivas de síndrome de Incontinentia Pigmenti, confirmada por biópsia de pele. Conclui-se que o diagnóstico precoce é essencial, pois as lesões retinianas podem levar a sequelas graves e cegueira.

Incontinentia Pigmenti (Bloch-Sulzberger syndrome) is a rare, X-linked dominant disorder that involves ectodermal tissues of multiple systems. Cutaneous manifestations appear at birth or within a few weeks after. We aimed to describe ophthalmological, dermatological and radio diagnostic findings of a patient with Incontinentia Pigmenti. A twenty-six year old girl was followed at ABC Medicine School for visual loss, retina and cutaneous lesions with the diagnosis of Incontinentia Pigmenti confirmed by a skin biopsy. She had delayed eruption of her teeth some of which were conical. To conclude early management of retinal changes in Incontinentia Pigmenti is essential because they may be serious leading to blindness.

Incontinentia Pigmenti in a Male Infant / 대한피부과학회지

Incontinentia pigmenti (IP) is an uncommon genodermatosis that occurs mostly in female infants, but is rarely found in male infants. Male patients with incontinentia pigmenti are usually more severely affected than their female counterparts. IP is characterized by ectodermal, mesodermal, neurological, ocular, and dental manifestations. Herein, we report a case of IP in a male infant who presented with a typical course of skin manifestation, dental defects, and recurrent partial seizures. However, he did not show any signs or symptoms for ocular or cardiovascular anomalies.

A case of incontinentia pigmenti

Down syndrome is the most common autosomal chromosomal abnormality characterized by mental and growth retardation, and by various typical features including prominent epicanthal fold, oblique palpebral fissure, flat nasal bridge, short and broad hand, wide toe interspace, etc. The overall incidence has been shown to be 1:800 deliveries, increasing with advancing maternal age. However, twin cases are extremely rare, and thus far only 500 cases were reported worldwide. We have recently observed 10-day-old male monozygotic twins with Down syndrome, born to a mother of 30 years of age with one normal child. Both have VSD confirmed by 2D-echocardiography, in addition to various typical features. Cytogenetic examination revealed that both have karyotypes of 47, XY, +21. This is the first report in Korea as the authors are aware of.
