Excellent effect of steroid plus azathioprine in a young woman with pernicious anaemia and systemic lupus erythematosus.

We describe a 29-year-old woman who developed pernicious anaemia 2 years after the diagnosis of systemic lupus erythematosus. This is a rare association despite the relationship between the autoimmune aetiologies of these two conditions. Seven other cases have been described, but our report demonstrates a case with an excellent response to steroid and azathioprine.
