Polymyositis as a cause of malabsorption. A case report.

We report on a patient with polymyositis which caused a malabsorption syndrome. The radiological findings included marked dilatation of the oesophagus and small intestine. The malabsorption syndrome appears to arise from bacterial overgrowth associated with intestinal stasis. The literature is reviewed. Polymyositis or dermatomyositis, like scleroderma, may involve the small bowel and cause the malabsorption syndrome.
