This report deals with the problems of a young man who was clinically euthyroid but biochemically hyperthyroid. The possibility of peripheral resistance to thyroid hormones to explain this paradoxical state is discussed. The importance of recognising this condition to avoid the erroneous diagnosis of thyrotoxicosis and inappropriate therapy is stressed.
