title: Ureteral necrosis in dermatomyositis.
abstract: We describe a child with dermatomyositis and calcified necrosis in the middle third of both ureters. Histopathological examination showed vasculitis associated with ureteral necrosis and calcification. These findings together with a similar previous report in the literature have prompted us to correlate dermatomyositis in childhood with ureteral necrosis and to anticipate specifically a lesion in the middle third of the ureter because of the relative lack of blood flow in that segment.
