Síndrome de Bart: aplasia cutis congénita y epidermólisis bullosa / Bart's syndrome: aplasia cutis congenita and epidermolysis bullosa

La aplasia cutis congénita, también conocida como síndrome de Bart, ha sido asociada con todos los subtipos principales de epidermólisis bullosa. Esta enfermedad afecta a 1 por cada 10 000 recién nacidos vivos; solo se han descrito 500 casos en la literatura médica. Se caracteriza por afectar un miembro inferior con patrón en forma de S y presentar lesiones de epidermólisis bullosa en cualquier otra parte del cuerpo. Se presenta el caso de una neonata con las características clínicas mencionadas, hospitalizada en el Servicio de Neonatología del Hospital Pediátrico Universitario «José Luis Miranda». Este diagnóstico es principalmente clínico y se basa en la evidencia de áreas de pérdida cutánea con predominio en miembros inferiores, lesiones ampollares en piel y mucosas, y deformidades ungueales. Su pronóstico puede ser fatal. Este caso reviste gran interés por su baja incidencia; su diagnóstico precoz contribuyó a evitar complicaciones.

Aplasia cutis congenita, also known as Bart's syndrome, has been associated with all the major epidermolysis bullosa subtypes. This disease affects 1 in 10, 000 live births; only 500 cases have been described in medical literature. It is characterized by affecting a lower limb with an S-shaped pattern and presenting epidermolysis bullosa lesions in any other part of the body. We present a female neonate with the aforementioned clinical features, who was hospitalized in the Neonatology service at "José Luis Miranda" Pediatric University Hospital. This diagnosis is mainly clinical and is based on evidence of areas of skin loss predominantly on the lower limbs, bullous lesions on the skin and mucous membranes and nail deformities. Its prognosis can be fatal. This case is of great interest due to its low incidence; its early diagnosis helped to avoid complications.

Aplasia cutis congénita extensa de miembro inferior: presentación de un caso / Extensive aplasia cutis congenita of lower limb: case report

La Aplasia Cutis Congénita es una afección in-frecuente caracterizada por la ausencia de piel al nacer. Su localización más frecuente es en vértex, siendo rara en miembros inferiores como es el caso de nuestra paciente. La misma puede presentarse de forma aislada o asociada a otras anomalías o alteraciones genéticas. Analizamos el caso de una paciente de sexo femenino, con antecedente de consumo de marihuana materno durante la gestación, que presenta una aplasia cutis congénita extensa de miembro inferior derecho con acorta-miento del mismo a expensas de partes blandas, sin otras anomalías asociadas a la que se le realizó tratamiento tópico con gel antiséptico y apósitos glicerinados estériles con buena evolución y sin complicaciones.

Aplasia Cutis Congenita is an infrequent condi-tion characterized by the absence of skin at birth. The most frequent location is the scalp, being rare in lower limbs as is the case of our patient. It can be an isolated condition or be associated with other anomalies or genetic disorders. We analyzed the case of a female patient, with a history maternal use of marijuana during pregnancy, who presented a congenital extensive aplasia cutis of the right lower limb, with shortening at the expense of soft parts, without other abnormalities associated, who received topical treatment with antiseptic gel and sterile glycerinated dressings with good evolution and without complications.

Síndrome de bart: A propósito de un caso / Bart syndrome: Report of a case

El síndrome de Bart es un trastorno congénito poco frecuente, caracterizado por la asociación de epidermólisis ampollosa, ausencia congénita localizada de piel y ocasionalmente anormalidades ungueales. En este artículo se reporta el caso de un neonato masculino, remitido al Hospital para el Niño del IMIEM (Instituto Materno-Infantil del Estado de México), para valoración de lesiones ampollosas extensas y ausencia de piel en miembros inferiores, presentes desde el nacimiento quien después del tratamiento, mostró mejoría con una evolución clínica favorable.

Bart syndrome is a rare congenital disorder characterized by the association of epidermolysis bullosa, localized congenital absence of skin and occasionally nail abnormalities. In this presentation we report the case of a male neonate referred to the Hospital para el Niño of IMIEM for evaluation of extensive blistering lesions and absence of skin in lower limbs, present from birth and who after treatment showed improvement, with a favorable clinical evolution.

Aplasia cutis: revisão de literatura e relato de caso / Aplasia cutis: literature review and case report

Aplasia cútis congênita (ACC) é uma doença rara, caracterizada pela ausência de formação completa da pele. Geralmente ocorre no couro cabeludo, na linha mediana, e se apresenta ao nascimento como uma ferida que pode atingir diferentes profundidades e envolver o periósteo, crânio e dura-máter. Apresentamos dois casos de recém-nascidos com aplasia cútis congênita no couro cabeludo que foram tratados no Centro de Atendimento Integral ao Fissurado Lábio Palatal de Curitiba- Paraná. Devido à raridade da ACC e ao pequeno número de pacientes nas séries publicadas na literatura, a padronização do tratamento ainda é incipiente. O propósito do presente trabalho é realizar uma revisão da literatura sobre os aspectos epidemiológicos, diagnóstico e formas de tratamento da ACC de couro cabeludo.

Aplasia cutis congenital (ACC) is a rare disease characterized by the absence of skin formation. Usually occurs on the scalp, in the midline, and presents at birth as a wound that can reach different depths and can involve the periosteum, skull and dura. We present two cases of newborns with congenital cutis aplasia on the scalp that were treated at the Center for Integral Assistance of Cleft Lip and Palate Curitiba-Paraná. Due to the rarity of ACC and the small number of patients in published series in the literature, standardization of treatment is still a challenge. The purpose of this paper is to review the literature on the epidemiology, diagnosis and treatment modalities of ACC of the scalp.

Aplasia cutis congénita: tratamiento con apósitos de quitosano / Aplasia cutis congenita: treatment with dressings chitosan

La aplasia cutis congénita es una patología poco común y localizada, que se caracteriza por la ausencia total o parcial de las capas cutáneas y en la mayoría de los casos se cura espontáneamente. Presentamos el caso de un recién nacido a término, de sexo masculino que al momento de nacimiento presenta una lesión erosiva que abarca rodilla, pierna, tobillo y dorso de pie izquierdos. La superficie de la lesión es roja, brillante y está cubierta por una fina membrana traslúcida, que permite la visualización de estructuras vasculares. Por los antecedentes y la clínica se llega al diagnóstico de aplasia cutis congénita. Se decide realizar tratamiento utilizando apósitos oclusivos con Quitosano (Biopiel ®). A la semana de iniciadas las curaciones, es evidente el avance de la cicatrización, la cual alcanza a ser completa al mes y medio de vida. Actualmente el paciente tiene 6 años de vida y no presenta nuevas lesiones, solo muestra secuelas pigmentarias con tendencia a la resolución. La aplasia cutis congénita suele presentarse sola o como parte de un grupo heterogéneo de síndromes. Su incidencia es de 1 a 3 por 10.000 nacimientos. La mayoría de los casos son esporádicos y la etiología aun es desconocida. El 85% de los casos se presentan en el cuero cabelludo, a nivel del vértex, sin embargo, se puede localizar en tronco o extremidades. El diagnóstico de aplasia cutis congénita es fundamentalmente clínico, ya que la histopatología es poco específica. El tratamiento en la mayoría de los casos es conservador. La importancia de presentar este caso clínico es para destacar que un correcto diagnóstico de Aplasia cutis congénita, permite realizar un tratamiento conservador, que en este caso tuvo un resultado muy favorable, tanto en la funcionalidad como en la apariencia estética del miembro afectado, evitando someter al neonato a riesgos mayores.

Aplasia Cutis Congénita is an uncommon and localized disorder, whose main future is the partial o complete absence of the cutaneous layer and on most cases heals spontaneously. We report a case of a male newborn, that presents at birth an erosive lesion that involves left knee, leg, ankle an back of the left foot. The surface of the erosive lesion is red, shiny and covered by a thin translucent membrane, which allows visualization of vascular structures. The clinical diagnosis was aplasia cutis congenita. Treatment with Chitosan ( Biopiel ®) oclusive dressings is started.The progress of the healing process is evident in the first week of treatment and is complete to month and a half of life. Currently the patient is 6 years old and he presents only hypopigmentation an hyperpigmentation but absence of new erosive injuries. Aplasia cutis congenita is an anomaly that can be present isolated or as a part of a syndromic condition. Most cases are sporadic and the etiology remains unknown. The incidenece is about 1:3 / 100.000. 85% of the cases are localizated on the scalp nevertheless ACC can be present on the trunk or extremities. The diagnosis of ACC is basically clinical, since the histopathological findings are non-especific. The management is mainly conservative. The purpose of presenting these case is for highlighting the importance to make a correct diagnosis for achive a favorable result both aesthetic and funcional through a conservative treatment.

First Case Report of an Infant with Aplasia Cutis Congenita of Scalp and Myelomeningocele / Primeiro relato de caso de aplasia cutis congenita e mielomeningocele

Aplasia cutis congenita of scalp (ACCS) is a rare developmental anomaly. It has presented in children who have many concomitant anomalies. Large, deep defects can complicate by repeat local and systemic sepsis and life-threatening hemorrhage. In this paper, we describe, to the best of our knowledge, the first case of a newborn boy with ACCS and myelomeningocele whose evolution with hydrocephalus has brought us a serious paradigm of using a shunt in the presence of tissue expanders. The treatment of hydrocephalus with third ventriculostomy associated with good aesthetic final result show an alternative to the use of shunt in this scenario, even in infants of young age. We review here therapeutic strategies and challenges with this disease.

A aplasia cútis congênita do couro cabeludo (ACC) é uma rara anomalia do desenvol- vimento. Tem sido observada em pacientes com outras deformidades associadas. Formas extensas e profundas podem evoluir com septicemia e hemorragia grave. Neste trabalho descrevemos um caso inédito de neonato do sexo masculino com ACC e espinha bífida na qual a evolução com hidrocefalia nos trouxe um dilema em usar shunt na presença de expansores teciduais. O tratamento com terceiroventriculostomia endoscópica associado a um bom resultado estético revela uma alternativa ao uso de derivações neste cenário, mesmo em lactentes. Revisamos aqui as opções terapêuticas e desafios encontrados nesta patologia.

Aplasia congênita da cútis em membros inferiores: relato de caso / Aplasia cutis congenita on the lower limbs: a case report

INTRODUÇÃO A Aplasia Congênita da Cútis (ACC) é uma doença rara caracterizada pela ausência de uma parte da pele ao nascimento, seja em área localizada ou generalizada. A incidência é de 0,1 a cada 100.000 nascimentos, tendo como acometimento principal o couro cabeludo, ocorrendo de forma isolada nesta localização em 60% dos casos. As causas não são claras, mas fatores genéticos, teratógenos (álcool, cocaína, maconha, heroína, misoprostol, metimazol, carbimazol, herpes simples congênito, varicela congênita, etc.), comprometimento da irrigação sanguínea para a pele, trauma, bandas amnióticas e desordens cromossômicas (trissomia do 13) estão associados com as lesões. RELATO DO CASO: Paciente do sexo feminino, nascida de parto vaginal com 36 semanas e três dias, e peso adequado para a idade gestacional. Referenciada ao nosso serviço após sete dias de nascimento, constando ausência total do tegumento cutâneo em ambas as pernas, com acometimento de aproximadamente 17% da superfície corpórea, segundo a tabela de queimados de Lund e Browder. A má formação consistia na ausência total de pele e tecido celular subcutâneo. Face a extensão e localização da lesão, optou-se pelo tratamento por enxerto de pele parcial, permitindo, dessa forma, preencher a totalidade do defeito. CONCLUSÃO: Devido à raridade da ACC e ao pequeno número de pacientes nas séries publicadas na literatura, a padronização do tratamento ainda é incipiente e o que existe são recomendações. Ainda são necessários estudos que abordem desde a etiologia da doença até a avaliação dos métodos de tratamento.

INTRODUCTION Aplasia cutis congenita (ACC) is a rare disease characterized by the absence of a part of the skin at birth that may be either localized or widespread. The incidence of this disease is 0.1 per 100,000 births. It mainly involves the scalp alone in 60% of the cases. The causes are unclear; however, genetic factors, teratogens (alcohol, cocaine, marijuana, heroin, misoprostol, methimazole, carbimazole, congenital herpes simplex, congenital varicella, and others), impaired blood supply to the skin, trauma, and amniotic band and chromosomal disorders (trisomy 13) are associated with the wounds. CASE REPORT: A female patient was delivered vaginally at 36 weeks 3 days of gestation, with appropriate weight for the gestational age. She was referred to our service after 7 days of birth, presenting total absence of skin integument on both legs, with impairment of approximately 17% of the body surface according to the Lund and Browder chart. The malformation consisted of the total absence of skin and subcutaneous tissue. Given the extent and localization of the wound, treatment with a partial skin graft was elected, thereby filling the totality of the defect. CONCLUSION: Owing to the rarity of ACC and the small number of patients in the series published in the literature, standardization of treatment is still incipient. Currently, only recommendations are available. Further studies are needed in order to investigate the etiology of the disease and to evaluate treatment methods.

Fenotipo grave en dos medio hermanas con síndrome de Adams Oliver / Severe phenotype in two half-sibs with Adams Oliver syndrome

El síndrome de Adams Oliver (AOS) es una entidad heterogénea con defecto transverso terminal de extremidades (TTLD) y aplasia cutis congénita (ACC) con un amplio espectro fenotípico. Se han descrito diferentes modos de herencia en esta enfermedad; los defectos más graves se han asociado a un patrón autosómico recesivo (AR). Objetivo. presentar a una familia con dos medio hermanas con un fenotipo grave de Adams Oliver, con una madre sana. Reporte del caso: una mujer de 27 años de edad fue referida al Departamento de Genética. Su hija anterior presentó acránea, anillos de constricción y defectos transversos terminales de extremidades. Su hija actual presentaba encefalocele occipital, defecto amplio en huesos del cráneo, aplasia cutis congénita, defecto terminal transverso de extremidades y labio y paladar hendido bilateral. Sugerimos que algunos casos con fenotipo grave del síndrome de Adams Oliver pueden deberse a herencia autosómico dominante con penetrancia incompleta o a la presencia de mosaicismo gonadal.

Adams Oliver syndrome (AOS) is a highly variable entity with terminal transverse limb defects (TTLD) and aplasia cutis congenita (ACC) with a wide phenotypic spectrum. Several inheritance models have been observed; the most severe phenotype has been related to an autosomal recessive (AR) pattern of inheritance. Objective. To present a family with two half siblings with a severe phenotype of Adams Oliver syndrome in which the mother was healthy. Case report: A 27 year-old woman was referred to the Genetics Department. Her previous girl presented acrania, constriction rings and terminal transverse limb defects. The present girl had occipital encephalocele, large scalp defects, aplasia cutis congenita, terminal transverse limb defects and bilateral cleft lip and palate. Autosomal dominant inheritance with reduced penetrance or gonadal mosaicism has to be considered in Adams Oliver syndrome with severe intracranial anomalies.

Infección intrauterina por Herpes virus simplex y aplasia cutis / Intrauterine Herpes simplex virus infection and aplasia cutis

Presentamos un caso de infección por Herpes virus simplex adquirido por vía transplacentaria en un neonato nacido a las 34 semanas de gestación por parto vaginal. La madre presentó un único episodio de infección genital por herpes virus en la décima semana de gestación.En el momento del nacimiento el niño presentódos ampollas y lesiones de aplasia cutis que semejaba una epidermólisis bullosa. Además, se evidenciaron múltiples anomalías congénitas del sistema nervioso central, oftalmológicas y cardíacas que sustentan la infección herpética intrauterina. El test de Tzanck y la serología para Herpes virus simplex 2 (IgG) fueron positivas. La infección intrauterina por virus herpes está asociada a alta morbilidad y mortalidad pero responde a la terapia antiviral. Este diagnóstico debe ser considerado en todo neonato con una enfermedad ampollar o piel erosionada.

We present a case of Herpes simplex virus infection acquired by transplacental route in a neonate born at 34 weeks of gestation by vaginal delivery. The mother presented a single episode of genital herpes simplex virus infection in the tenth week of pregnancy. At birth, the neonate presented two blisters and lesions of aplasia cutis resembling epidermolysis bullosa. In addition, he presented multiple congenital anomalies of the brain, eyes and heart, supporting the intrauterine infection. Tzanck test and serology for Herpes simplex virus 2(IgG) were positive. Intrauterine infection by herpes virus is associated with high morbidity and mortality, however it responds to antiviral therapy. This diagnosis should be considered in any neonate with blisters or denuded skin.

An Unusual Association of Aplasia Cutis Congenita with Twin Pregnancy and Maternal Varicella.

We report an unusual case of aplasia cutis congenita associated with twin pregnancy and history of maternal varicella in first trimester, occurring over the extremity of one of the twins while other twin was perfectly normal.

Un caso de síndrome de Adams-Oliver con venas congénitas, dilatadas y persistentes en el cuero cabelludo / A case of Adams-Oliver syndrome with congenital and persistent dilated veins in the scalp

El síndrome de Adams-Oliver es un desorden congénito raro, caracterizado por la presencia de aplasia cutis congénita y defectos terminales transversos de los miembros. Comunicamos el caso de una niña de 4 años de edad con síndrome de Adams-Oliver que presenta venas congénitas, tortuosas y dilatadas en el cuero cabelludo, aplasia cutis congénita con defectos parciales del hueso craneal subyacente, calcificaciones intracraneales y anomalías leves de los pies.

Adams-Oliver syndrome is a rare congenital disorder characterized by aplasia cutis congenita and terminal transverse limb defects. We report a case of a 4-year-old girl with Adams-Oliver syndrome with congenital dilated and tortuous scalp veins, aplasia cutis congenita with partial underlying skull defects, intracranial calcifications, and mild foot anomalies.

Aplasia cutis congénita: serie de casos de ubicación y asociación particular / Aplasia cutis congenita: a case series

La aplasia cutis congénita (ACC) es un trastorno poco frecuente del desarrollo cutáneo, presentándose la mayoría como defectos aislados, pero pueden asociarse a otras malformaciones y síndromes genéticos. En relación a un caso de ACC extensa asociada a Síndrome de Adams-Oliver (SAO) se analizaron 10 casos de ACC con ubicación especial o asociadas a otras malformaciones diagnosticadas en forma clínica o por ecografía. Se confeccionó una tabla clasificando cada caso según Frieden, describiendo la ubicación de la aplasia y las asociaciones encontradas.

Aplasia cutis congenita (ACC) is a rare disorder of skin development, appearing mostly as isolated defects, but may be associated with other malformations and genetic syndromes. In relation to a case of extensive associated ACC Adams-Oliver Syndrome (AOS) were analyzed 10 cases of ACC with special location or associated with other malformations diagnosed clinically or by ultrasound. We made a table classifying each case as Frieden`s classification, describing the location of the aplasia and the associations found.

Aplasia Cutis Congenita in Two Siblings / 대한피부과학회지

Aplasia cutis congenita is a rare congenital condition, characterized by localized absence of epidermis, dermis, and in some cases, subcutaneous tissues. About 80% of the patients with aplasia cutis congenita have involvement of the scalp. Aplasia cutis congenita, not involving the scalp, appears to be linear lesions with a symmetrical pattern of distribution on the trunk and limbs. Most reported cases are sporadic, but a few cases have been reported to have familial occurrence. There is no unifying theory for the pathogenesis and etiology. Herein, we report a 1-day-old female infant and her 4-year-old sister with unilateral aplasia cutis congenita on their legs. No similar conditions and other associated congenital anomalies were found in their family. There was no sign of teratogenic causes, such as intrauterine infections, drugs or chemical agents.

Aplasia cutis congénita tipo I: aporte de un caso / Aplasia cutis congenita: a case report

La Aplasia Cutis Congénita, es un grupo heterogéneo de alteraciones que consisten en la falta congénita localizada o extensa, de piel, que puede acompañarse de ausencia de estructuras subyacentes. Su apariencia clínica es variable y su origen es multifactorial. Presentamos el caso de un recién nacido con Aplasia Cutis Congénita, sin antecedentes familiares de esta enfermedad ni historia de uso materno de drogas, en quien no se constataron hallazgos extracutáneos.

Congenital aplasia cutis, is a heterogeneous group of disorders that involve the congenital absence, localized or extensive, of the skin, which may be accompanied by the absence of underlying structures. Its clinical appareance is variable with a multifactorial origin. We report the case of a newborn with Congenital Aplasia Cutis with no family history of the disease or history of maternal drug abuse, in whom extracutaneous findings were not found.

Aplasia Cutis Congenita of the Scalp Accompanied by Limb Hypoplasia: Adamson-Oliver Syndrome / 대한피부과학회지

Aplasia cutis congenita (ACC) is an uncommon condition which is characterized by congenital, localized or widespread absence of skin or scar formation. Lesions can be multiple and may occur on any body surface, although they are mostly seen on the scalp as a solitary lesion. ACC is most often a benign isolated defect; but it can be associated with other physical anomalies or malformation syndromes. Adams-Oliver syndrome is a distinct subtype in which distal limb reduction is found in association with a solitary scalp defect. There is no single underlying cause of ACC; it may reflect a disruption of intrauterine skin development. A 25 day-old boy was referred to our clinic with a thick hemorrhagic crust, and a surrounding hairless atrophic scar on the midline over the skull vertex. He also had hypoplasia of the left 2nd to 5th toes since birth. The rest of the physical examination as well as an ultrasound examination of the brain were normal. Herein we report a rare case of ACC of the scalp accompanied by distal limb hypoplasia, Adamson-Oliver syndrome.

Clinical Course of Aplasia Cutis Congenita

PURPOSE: Aplasia cutis congenita (ACC) is a rare condition characterized by a localized absence of skin, and it can be associated with other congenital anomalies. This study was done to evaluate clinical course and outcome of ACC in neonates. METHODS: Based on the medical records, we retrospectively reviewed 8 neonates diagnosed with ACC at Cheil General Hospital and Women's Health Care Center, Kwandong university College of Medicine from January 2004 to December 2010. We classified ACC by Frieden's classification and analyzed the patient's demographic data, clinical course and outcome. RESULTS: Among 8 patients with ACC, 5 patients were classified to group 1; scalp ACC without anomalies and 3 patients to group 7; ACC localized to extremities without blistering. Defect size was from 0.3 cm to 1.5 cm, limited in the superficial skin or subcutaneous tissue without associated anomalies. Defects were healed under conservative treatment with mild scar formation within four months. CONCLUSION: ACC could be diagnosed easily through physical examination in neonates. All cases showed good clinical outcome without surgical treatment. However because of small numbers and small sized defects of cases, further study including lesions of large size is needed.

A Case of Aplasia Cutis Congenita in Two Siblings / 대한피부과학회지

Aplasia cutis congenita (ACC) is a rare congenital disorder, which was first described by Cordon in 1767. It is characterized by a defect of epidermis, dermis, subcutaneous tissues and sometimes even bone, and occurs predominantly on the scalp. Non-scalp locations are involved in 15% of all cases and are often bilaterally symmetrical. Most cases of ACC appear sporadically. Intrauterine trauma, vascular accidents or genetic factors are postulated as initial steps in the pathogenesis. However, the aetiology of this condition remains unknown. Familial cases have been reported and are suggestive of either an autosomal dominant or autosomal recessive inheritance with variable expression. We herein report on a 10-day-old female infant and her 8-year-old sister with aplasia cutis congenita on their legs.

A Case of Adams-Oliver Syndrome

Adams-Oliver syndrome (AOS) is a congenital condition characterized by aplasia cutis congenita, transverse limb defects, and cutis marmorata telangiectatica. AOS can also be associated with extensive lethal anomalies of internal organs, including the central nervous, cardiopulmonary, gastrourointestinal, and genitourinary systems. Generally, the more severe these interrelated anomalies are, the poorer the prognosis becomes. In the relevant literature on this topic, it is somewhat unclear as to whether the prognosis of AOS without lethal anomalies alters the lifespan. We report a case of AOS with typical skin defects only, and no internal organ anomalies.

Aplasia cutis asociada a infartos placentarios / Aplasia cutis associated with placental infarcts

La aplasia cutis congénita (ACC) se define como la ausencia congénita parcial o total de piel que puede presentarse en forma aislada o asociada a otras anomalías o síndromes. Se clasifica en nueve grupos de acuerdo al sitio anatómico donde asienta, a la configuración que adopta, a las anomalías asociadas y etiologías probables. Presentamos un recién nacido, pretérmino extremo, con una ulceración de gran extensión, de forma estelar ubicada en la región lumbosacra. El estudio anatomopatológico de la placenta informó microinfartos isquémicos múltiples. Habiendo descartado otras causas (farmacológicas, hereditarias, tóxicas e infecciosas) así como la ausencia de anomalías del desarrollo, se llegó al diagnóstico de ACC grupo 5, relacionada con microinfartos placentarios. La ACC es una patología poco frecuente y la importancia de su diagnóstico radica en descartar anomalías del desarrollo u otras asociaciones subyacentes.

Congenital aplasia cutis (CAC) is the complete or partial absence of skin that might present alone or associated with others abnormalities or syndromes. It is classified in nine groups, according to the anatomic site where it settles, the lesions appearance, the presence or absence of associated malformations and the probable aetiology. We present an extremely preterm new born with extensive and stellate ulceration, located in the lumbosacral area. The placenta histological findings revealed multiple ischemic infarcts. After ruling out pharmacologic, toxic, infectious causes, or family history, and without evidence of malformation syndromes, we arrived to the diagnose group 5 CAC, associated with placental microinfarctions. Aplasia cutis is a rare clinical finding and it is important to make the correct diagnosis due to the possible associated abnormalities and syndromes than we can found.
