		| Abstract | 
	 
	
		| 
		Antithyroid drugs are the most common treatment modality for Graves' disease and are used for the treatment of relapsed Graves' disease in Korea. Agranulocytosis is a rare and severe complication of antithyroid drug therapy, and most cases occur within 3 month after drug treatment. Agranulocytosis can develop in patients who have relapsed Graves' disease and undergo a second course of antithyroid drugs with a prior uneventful course of drug therapy. 
We report a case of antithyroid drug-induced agranulocytosis in a relapsed Graves' disease patient who had undergone prior uneventful antithyroid drug therapy. We also present a review of the relevant literature. (Korean J Med 75:362-366, 2008)		 |
