[Digestive manifestations of dermatomyositis (author's transl)].

The principal digestive anomalies detected by radiological examination in dermatomyositis are the motor and functional consequences of the smooth and striated muscle lesions in these tissues. Vascular changes cause ulcerations, located in any part of the digestive tract, but more frequently in the esophagus, duodenum, and small intestine. These ulcerations sometimes develop into pseudodiverticulae.
