This is a self-limiting disease that goes away after 6-8 weeks without treatment. Fibrosis is only present in the late stages of this condition, either right before or after remission. This indicates that this sample was taken from a patient who had late-stage subacute granulomatous thyroiditis. This also explains why there are so few giant cells present.
