亚急性肉芽肿性甲状腺炎(Dequervain病),它的发生可能与病毒感染有关。甲状腺肿大伴有疼痛。为自限性疾病，病程为数周到数月不等，过后甲状腺功能恢复正常。可见破坏甲状腺滤泡的异物巨细胞。
This is subacute granulomatous thyroiditis (DeQuervain's disease), which probably follows a viral infection and leads to a painful enlarged thyroid. This disease is usually self-limited over weeks to months and the patients return to a euthyroid state. Note the foreign body giant cells with destruction of thyroid follicles.
