Tiña de la cabeza - Symptom

Nombres alternativos

Infección micótica del cuero cabelludo; Infección del cuero cabelludo; Infección en el cuero cabelludo por hongos; Tiña del cuero cabelludo; Tiña tonsurante

Síntomas:

La tiña de la cabeza puede comprometer todo el cuero cabelludo o sólo partes de éste. Las áreas infectadas aparecen calvas con pequeños puntos blancos, debido al cabello que se ha desprendido.

Se pueden encontrar áreas de piel redondas y descamativas que pueden estar rojas o hinchadas (inflamadas), al igual que úlceras llenas de pus llamadas queriones.

Se puede presentar fiebre baja de alrededor de 100 a 101º F (37.5 a 38º C) o ganglios linfáticos inflamados en el cuello.

Generalmente hay picazón en el cuero cabelludo.

Signos y exámenes:

El aspecto del cuero cabelludo llevará al médico a sospechar la presencia de tiña de la cabeza. Una lámpara especial, llamada examen con lámpara de Wood, puede ayudar a diagnosticar una infección micótica del cuero cabelludo.

El médico puede frotar el área con algodón y enviar la muestra para un cultivo; sin embargo, pueden pasar hasta tres semanas para obtener los resultados.

En raras ocasiones, se hará una biopsia de lesión de piel del cuero cabelludo.
