Sarna - Symptom

Nombres alternativos

Sarcoptes scabiei

Síntomas:

  • Picazón, especialmente en la noche
  • Erupción cutánea, especialmente entre los dedos
  • Úlceras (abrasiones) sobre la piel por el rascado y la excavación
  • Líneas delgadas en la piel similares al trazo de un lápiz

Los ácaros pueden estar más extendidos en la piel de un bebé, lo que causa granos en el tronco o pequeñas ampollas en las palmas de las manos y plantas de los pies.

  • En los niños pequeños, las áreas comprometidas son la cabeza, el cuello, los hombros, las palmas de las manos y las plantas de los pies.
  • En los niños mayores y en los adultos, resultan comprometidas las manos, las muñecas, los genitales y el abdomen.

Signos y exámenes:

La evaluación de la piel muestra los signos de la sarna. Los exámenes incluyen un análisis bajo el microscopio de las muestras de piel tomadas del agujero para buscar los ácaros. También se puede tomar una biopsia de piel.
