ABSTRACT
Aplasia cutis congenita is a rare malformation characterized by localized congenital absence of the skin. It rarely occurs on the trunk and limbs, and can occur in isolation or as part of a heterogeneous group of syndromes. We report a case of a 4-day-old boy with a 5.6-cm- diameter tumor, with a central crust, non-indurate and no inflammatory rim; localized on the scalp and a small, atrophic hairless scar appeared 6 months later (approximately 5 cm in length) at the site of the previous tumor.

We report the case of an infant with Adams-Oliver syndrome, a rare disorder characterized by aplasia cutis congenita, defects of the limbs and extremities, and cutis marmorata telangiectatica. Other associated anomalies have been reported, such as facial dysmorphism, heart defects, and disorders of the central nervous system.

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.
