Thyroid storm secondary to acute Streptococcus pyogenes pharyngitis.

Thyroid storm is an endocrine emergency associated with high mortality rates, especially in hospitalized populations. Infection serves as an exceedingly common trigger for the development of thyrotoxicosis. We present a rare case of a 24-year-old woman who developed acute thyrotoxicosis secondary to group A Streptococcus throat infection. The patient received a combination of thionamides, antibiotics, glucocorticoid, beta-blocker, and iodine preparation that resulted in the resolution of her symptoms.
