Descriptor polimiositis
Entry term(s) miositis múltiple
Scope note: Enfermedades caracterizadas por inflamación de múltiples músculos. Pueden aparecer de forma aguda o crónica, asociadas a toxicidad medicamentosa (TOXICIDAD POR DROGAS), ENFERMEDADES DEL TEJIDO CONJUNTIVO, infecciones, NEOPLASIAS malignas, y otros trastornos. El término polimiositis se utiliza con frecuencia para referirse a una entidad clínica específica caracterizada por debilitamiento simétrico y progresivo, de carácter subagudo o de instauración lenta, que afecta principalmente a los músculos de los miembros superiores y del tronco. Esta enfermedad puede aparecer a cualquier edad, si bien es más frecuente entre la cuarta y la sexta décadas de la vida. También puede aparecer debilidad de los músculos faríngeos y laríngeos, neumopatía intersticial e inflamación del miocardio. Las biopsias musculares ponen de manifiesto destrucción generalizada de segmentos de fibras musculares y una respuesta celular de carácter inflamatorio.

Scope note: Diseases characterized by inflammation involving multiple muscles. This may occur as an acute or chronic condition associated with medication toxicity (DRUG TOXICITY); CONNECTIVE TISSUE DISEASES; infections; malignant NEOPLASMS; and other disorders. The term polymyositis is frequently used to refer to a specific clinical entity characterized by subacute or slowly progressing symmetrical weakness primarily affecting the proximal limb and trunk muscles. The illness may occur at any age, but is most frequent in the fourth to sixth decade of life. Weakness of pharyngeal and laryngeal muscles, interstitial lung disease, and inflammation of the myocardium may also occur. Muscle biopsy reveals widespread destruction of segments of muscle fibers and an inflammatory cellular response. (Adams et al., Principles of Neurology, 6th ed, pp1404-9)
