Systemic lupus erythematosus complicated with cystitis, obstructive uropathy and intractable diarrhea: report of a case.

A patient with systemic lupus erythematosus (SLE) displayed an unusual extraglomerular syndrome of cystitis with obstructive uropathy and severe secretory-type diarrhea. She had a history of idiopathic hypothyroidism and thrombocytopenia. The intractable diarrhea and cystitis with severe urinary obstruction regressed with large doses of systemic and intravesical corticosteroid therapy. The possibility of SLE should be considered fin any young female patient who has diarrhea of an unknown cause and cystitis.
