Abstract
Eosinophilic myositis is characterized by eosinophilic infiltration of skeletal muscles. In the absence of an identifiable causative factor or source (including parasitic infection, intake of drugs or L-tryptophan, certain systemic disorders as well as malignant diseases), the diagnosis of idiopathic eosinophilic myositis is usually retained. However, some muscular dystrophies have been recently identified in this subset of eosinophilic myositis. Here, we report a patient with an 8âkb CCTG expansion in intron 1 of the CNBP gene, a mutation characteristic of myotonic dystrophy type 2 (DM2), whose first manifestation was “idiopathic” eosinophilic myositis. This report suggests that in “idiopathic” eosinophilic myositis, clinicians should consider muscular dystrophies, including DM2.
