[Thyrotoxic periodic paralysis. A report of 2 cases].

Introduction: Thyrotoxic hypokalemic periodic paralysis is characterized by recurrent episodes of motor weakness of variable intensity associated with thyroid overactivity. It is usually associated with low plasma potassium levels and is often precipitated by physical activity or ingestion of carbohydrates.

Clinical Cases: We describe two men, aged 33 and 50, who complained of several episodes of muscular paralysis in the context of previously undiagnozed hyperthyroidism and associated with low plasma potassium levels.
