Definición

Son diminutas protuberancias blanquecinas o pequeños quistes en la piel que se observan casi siempre en los bebés recién nacidos.

Causas

Los milios ocurren cuando la piel muerta queda atrapada en pequeñas cavidades en la superficie cutánea o de la boca. Son comunes en bebés recién nacidos.

Quistes similares se observan en las bocas de los recién nacidos y se denominan perlas de Epstein. Estos quistes también desaparecen por sí solos.

Los adultos también pueden desarrollar milios en la cara. Las protuberancias y quistes también ocurren en partes del cuerpo que están hinchadas (inflamadas) o lesionadas. La sábanas o ropas ásperas pueden causar irritación de la piel y un enrojecimiento leve alrededor de la protuberancia, pero la parte media permanecerá blanca.

Algunas veces, a los milios irritados se les llama incorrectamente "acné del bebé". Esto es incorrecto, ya que los milios no son una verdadera forma de acné.

Síntomas

Los síntomas pueden incluir:

Protuberancias blanquecinas nacaradas en la piel de los recién nacidos
Protuberancias que aparecen a lo largo de las mejillas, la nariz y el mentón
Protuberancias blanquecinas y nacaradas en las encías o el paladar (algunas veces lucen como dientes que están saliendo a través de las encías)

Pruebas y exámenes

El proveedor de atención médica a menudo puede diagnosticar los milios simplemente examinando la piel o la boca. No se requiere ninguna prueba.

Tratamiento

No hay necesidad de tratamiento en los niños. Los cambios cutáneos en la cara o los quistes en la boca con frecuencia desaparecen después de las primeras semanas de vida sin tratamiento y sin efectos duraderos.

Los adultos se pueden hacer quitar los milios para mejorar su apariencia física.

Prevención

No hay una forma de prevención conocida.
