Queratosis actínica - Treatment

Nombres alternativos

Queratosis solar; Cambios queratósicos en la piel inducidos por el sol; Queratosis actínica solar

Tratamiento:

Debido a que aproximadamente el 5% de las queratosis actínicas continúan hasta transformarse en cáncer de piel escamocelular, procure hacérselas examinar oportunamente. Siga las instrucciones del médico para el tratamiento.

Los tumores o neoplasias se pueden extirpar por medio de:

  • Quemado (electrocauterización).
  • Raspado y uso de la electricidad para destruir cualquier célula remanente (llamado legrado y electrodesecación).
  • Extirpación del tumor y suturas para colocar la piel de nuevo (llamado escisión).
  • Congelación (crioterapia que congela y destruye las células).

Cuando se encuentran muchas queratosis actínicas, se utilizan tratamientos que causan irritación y enrojecimiento sobre un área grande:

  • Un tratamiento con láser llamado terapia fotodinámica.
  • Exfoliación de la piel.
  • Cremas, como 5-fluorouracilo (5-FU) e imiquimod.

Expectativas (pronóstico):

La queratosis actínica en sí es inofensiva (benigna), pero aproximadamente el 5% se transforma en cáncer de piel.

La extirpación del tumor generalmente es efectiva.

Complicaciones:

  • Irritación y molestia del tumor de piel.
  • Cicatrización a raíz del tratamiento.
  • Carcinoma escamocelular.

Situaciones que requieren asistencia médica:

Solicite una cita con el médico si se presentan áreas de aspereza o descamación persistente en la piel expuesta al sol.
