RESUMENLa incontinencia pigmenti (síndrome de Bloch-Sulzberger) es una genodermatosis rara causada por una mutación en el gen NEMO localizado en el cromosoma X. Las manifestaciones cutáneas son marcadoras de esta entidad y se dan de forma temprana y cronológica. El compromiso extra cutáneo se da hasta en el 80% de los casos y las alteraciones neurológicas y oftalmológicas son marcadores del pronóstico porque tienen el potencial de producir secuelas irreversibles. Se presenta el caso de una paciente que desde el primer día de vida inició con lesiones cutáneas que, con la evolución, desarrollaron características clásicas de una incontinencia pigmenti. Se resalta el antecedente familiar asociado, el compromiso neurológico extenso y la importancia de un manejo multidisciplinario. Palabras clave: incontinencia pigmentaria; manifestaciones cutáneas; signos y síntomas. ABSTRACTIncontinentia pigmenti (Bloch-Sulzberger Syndrome) is a rare genodermatosis. The disease is X-linked and the most common molecular defect includes mutations in the NEMO gene on chromosome Xq28 in approximately 70% of patients. It is characterized by a multisystem compromise in which the skin manifestations occur in all patients. Also, the dermatological findings occur early and in chronological order. The prevalence of extra skin compromise is approximately 80% of patients. The ophthalmological and neurological manifestations are the major cause of disability in patients and may have a great impact on the quality of life. Some of damages are irreversible. We present the clinical case of a child on her first day of life. It began with skin manifestations typical of incontinentia pigmenti and extensive neurological involvement. In addition, the family history includes a sister with the disease. A multidisciplinary approach is necessary to care for patients and to detect and prevent long-term complications.
