Two Cases of Localized Nodular Myositis
Abstract
- Localized nodular myositis is an uncommon benign inflammatory myopathy of unkonwn cause affecting skeletal muscle and, presenting as a localized painful swelling within the soft tissue of an extremity. Histological examination reveals lymphocytic infiltration, scattered muscle fiber necrosis and regeneration, and interstitial fibrosis. MRI finding is an enhancement with increased signal intensity around the lesion. We report two cases of localized nodular myositis presenting as pseudothrobothrombophlebitis. We believe this is the first case report of localized nodular myositis in Korea.
