Zusammenfassung

Idiopathische Myositiden sind erworbene Muskelerkrankungen, die teilweise auf eine immunmodulatorische Therapie ansprechen. Da auch bestimmte Muskeldystrophien und metabolische Erkrankungen entzündliche Infiltrate aufweisen können, ist die Kenntnis der diagnostischen Kriterien für den Neuropathologen von Bedeutung. Idiopathische Myositiden können generalisiert bzw. multifokal vorkommen (Dermatomyositis, Polymyositis, sporadische Einschlusskörperchenmyositis) oder fokal auftreten (z. B. proliferative Myositis, Makrophagenmyofasziitis). Diese Übersicht vermittelt diagnostische Kriterien für die Myositiden und – soweit bekannt – Daten zum pathogenetischen Mechanismus.

Abstract

Idiopathic inflammatory myopathies (IIM) are diseases that are potentially amenable to immunomodulatory therapy. The challenge for the neuropathologist consists in distinguishing these myopathies from secondary inflammatory myopathies, especially in the context of some muscular dystrophies and metabolic diseases that may also show inflammatory infiltrates. There are generalized IIMs (dermatomyositis, polymyositis, sporadic inclusion body myositis) and focal ones (e.g., proliferative myositis, macrophagic myofasciitis). This review provides diagnostic criteria for each of these and includes pathogenetic mechanisms where available.
