Focal myositis in monozygotic twins.
Focal myositis is a rare disease with unknown etiology and a broad spectrum. Here, we present two cases in monozygotic twins who complained of recurrent pain of their calves and showed histological signs of inflammation and MRI image compatible with the diagnosis of focal myositis. The occurrence of twin cases not living in the same household suggests a genetic susceptibility to the disease.
