title: Systemic lupus erythematosus with rectal stenosis simulating tumour or diverticulosis. Case report.
abstract: A case of systemic lupus erythematosus (SLE) with focal involvement of the rectum is reported. The lesion roentgenologically resembled a malignant tumour and was resected. Histologic examination disclosed only typical SLE changes in a very restricted area, with the remaining gastrointestinal tract unaffected. This appears to be the first report of focal colitis as a complication of SLE. The case points the importance of suspecting symptoms from any organ system in patients with connective tissue disorders to be manifestations of that underlying pathology.
