[Facial myositis: a localized form of generalized myositis?].

We report a case of myositis presenting as an apparently unique progressive facial weakness. The only biological abnormality after an 8-year follow-up was an immunocytoma. Molecular analyses excluded facioscapulohumeral muscular dystrophy. Based on this single case and a review of the literature, we suggest a continuum between focal myositis and generalized myositis.
