Systemic lupus erythematosus (SLE) is a multisystem connective tissue disease caused by the damage of tissues and cells by pathogenic auto-antibodies and immune complexes. A 27-year-old female presented with chronic diarrhoea was diagnosed as intestinal tuberculosis. But further evaluation diagnosed it a case of SLE and diarrhoea subsided with treatment. The case is reported because of its atypical presentation.
