Eritema tóxico

Definición

Es una afección cutánea común que se observa en los recién nacidos.

Causas

El eritema tóxico puede aparecer en aproximadamente la mitad de todos los bebés recién nacidos. La afección puede darse en las primeras horas de vida o puede aparecer después del primer día. La afección puede durar varios días.

Aunque el eritema tóxico es inofensivo, puede ser muy preocupante para los padres novatos. Su causa se desconoce, pero se piensa que está relacionado con el sistema inmunitario.

Síntomas

El síntoma principal es un sarpullido de protuberancias (pápulas) pequeñas y de color amarillo a blanco, circundada por piel enrojecida. Puede haber pocas o varias pápulas. Las cuales generalmente aparecen en la cara y en la parte media del cuerpo. También se pueden observar en la parte superior de los brazos y en los muslos.

El sarpullido puede cambiar rápidamente, apareciendo y desapareciendo en diferentes áreas en cuestión de horas a días.

Pruebas y exámenes

El proveedor de atención médica de su bebé con frecuencia puede hacer un diagnóstico durante un examen de rutina después del nacimiento. Generalmente no se necesitan exámenes. Si el diagnóstico no es claro se puede realizar un raspado de piel.

Tratamiento

 Las manchas rojas grandes usualmente desaparecen sin ningún tratamiento o cambios en el cuidado de la piel.

Expectativas (pronóstico)

El sarpullido usualmente desaparece en 2 semanas. Con frecuencia se ha ido completamente para la edad de 4 meses.

Posibles complicaciones

Cuándo contactar a un profesional médico

Si está preocupado hable de la afección con el proveedor de su bebé durante un examen de rutina.
