Lesión cutánea de blastomicosis - Overview

Definición:

Es un síntoma de una infección con el hongo Blastomyces dermatitidis. La piel resulta infectada a medida que el hongo se disemina por todo el cuerpo.

Causas, incidencia y factores de riesgo:

La blastomicosis es una infección micótica poco común que se presenta principalmente en los estados del centro y sudeste de los Estados Unidos, Canadá, India, Israel, Arabia Saudita y África. Una persona se infecta por la inhalación de partículas de hongo que se encuentran en el suelo húmedo, particularmente donde hay vegetación en descomposición. Las personas con trastornos del sistema inmunitario presentan el riesgo más elevado de contraer esta infección.

El hongo ingresa al cuerpo a través de los pulmones y los infecta. En algunas personas, el hongo se propaga (disemina) luego a otras áreas del cuerpo. La infección puede afectar la piel, los huesos y articulaciones, las vías genitourinarias y otros aparatos. Los síntomas cutáneos son un signo de blastomicosis generalizada (diseminada).
