Chronic lymphocytic, the most common... Now, this is interesting. Hashimoto. Hashimoto, most common cause of primary hypothyroidism in the US. Hypothyroidism. So, why is it under hyperthyroidism? Because of the following. Whenever you have inflammation, -itis, inflammation of the thyroid, there’s every possibility that the colloid… Can you picture the colloid for me? The homogenous eosinophilic central region of your thyroid cell that stores your, harbours my thyroid hormones. Any time there’s inflammation, that colloid “explodes”. You may then release your T3, T4 into circulation in great quantity. Welcome to thyroid storm.

Chronic lymphocytic thyroiditis. Acute bacterial (suppurative) thyroiditis – rare, but still possible. Subacute thyroiditis. What’s subacute mean? Slow, slow. Subacute thyroiditis. De Quervain, granulomatous thyroiditis. Once again, destruction release of… Colloid releasing T3, T4 excessively. Silent thyroiditis. We’ll talk about this post-partum especially, with delivery. We’ll see that coming up. Amiodarone. Amiodarone. Take a look at the “iod” in amiodarone. And doesn’t that resemble iodine?
