A Case of Recurrent Localized Myositis

ABSTRACT

We experienced a 41-year-old male patient with the recurrent painful nodular swelling of muscles in both lower limbs for 4 years. The mass did not accompanied other general symptoms of muscle weakness and spontaneously regressed. On pathologic finding, there is marked inflammatory cell infiltration with muscle fiber destruction and regeneration. Analyzing the literature, we proposed the diagnosis of recurrent localized myositis.
