Dermatomiositis - Overview

Definición:

Es un tipo de miopatía inflamatoria, una enfermedad muscular caracterizada por inflamación y erupción en la piel.

Causas, incidencia y factores de riesgo:

La causa de la dermatomiositis se desconoce, pero los expertos piensan que puede deberse a una infección viral de los músculos o a un problema con el sistema inmunitario del cuerpo. Además, puede ocurrir algunas veces en pacientes que tienen cáncer del abdomen, el pulmón u otra área corporal.

Cualquier persona puede desarrollar dermatomiositis, pero es más común en niños entre los 5 y los 15 años, y adultos entre 40 y 60 años. Las mujeres la presentan con mayor frecuencia que los hombres.

La polimiositis es una afección similar, pero los síntomas se presentan sin una erupción cutánea.
