Lesión cutánea de coccidioidomicosis - Overview

Definición:

Es un síntoma de una infección con el hongo Coccidioides inmitis.

Este artículo aborda las lesiones cutáneas debidas a coccidioidomicosis. Para obtener más información general sobre esta enfermedad, ver el artículo coccidioidomicosis.

Causas, incidencia y factores de riesgo:

La coccidioidomicosis es una infección micótica que se observa con mayor frecuencia en las regiones desérticas del suroeste de los Estados Unidos, al igual que en América Central y del Sur. La infección se adquiere por la inhalación de partículas de hongos, llamadas esporas, que se encuentran en el suelo infectado. La infección comienza en los pulmones.

Después de que los pulmones se infectan, el hongo puede diseminarse a otros tejidos, incluyendo la piel. La erupción cutánea o lesiones de la piel abarcan eritema nudoso o eritema multiforme y se cree que son causadas por una respuesta inmunitaria a la infección, más que por el hongo en sí.

Las lesiones cutáneas son un signo de enfermedad micótica generalizada (diseminada). Los que están en mayor riesgo de contraer una infección generalizada abarcan:

  • Personas descendientes de nativos americanos, africanos o filipinos
  • Personas con sistemas inmunitarios debilitados debido a SIDA, diabetes o medicamentos que inhiben el sistema inmunitario
