However, classification of idiopathic inflammatory myopathy into an existing clinical subtype is not always possible. The case is a 25-year-old male with an unrecognized form of idiopathic inflammatory myopathy, the onset of which resembled amyotrophic lateral sclerosis. The paper includes differential diagnosis with amyotrophic lateral sclerosis and congenital myopathies, and response to corticosteroid therapy.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Las miopatías inflamatorias idiopáticas son un grupo heterogéneo de enfermedades autoinmunes que tienen ciertas manifestaciones clínicas como la debilidad muscular y el aumento del nivel de creatinina quinasa del suero en la sangre. Sin embargo, no siempre es posible hacer la clasificación de miopatía inflamatoria idiopática en el subtipo clínico existente. El caso clínico presentado describe a un varón de 25 anos con una forma indeterminada de miopatía inflamatoria idiopática cuyo comienzo es parecido a la esclerosis lateral amiotrófica. En el trabajo se presenta el diagnóstico diferencial de esclerosis lateral amiotrófica y de miopatías hereditarias, así como la respuesta al tratamiento con corticosteroides.]]></p></abstract>
