<unk>  refers to an inflammation of the thyroid gland. It is classified into Hashimoto's<unk> , de Quervain's<unk> , silent<unk> , postpartum<unk> , Riedel's<unk> , and suppurative<unk> . These forms of<unk>  can be differentiated from each other on the basis of pathological and laboratory findings.<unk>  can lead to hypothyroidism or transient hyperthyroidism. The hypothyroid phase of<unk>  results from the gradual depletion of stored thyroid hormones. Chronic hypothyroidism is predominantly associated with hashimoto’s<unk> . However, all the types of<unk>  may progress to permanent hypothyroidism. Painless sporadic<unk>  (silent<unk> , painless postpartum<unk> , and painful subacute<unk>  (de Quervain's<unk>  usually lead to transient hyperthyroidism (thyrotoxicosis) when the preformed thyroid hormones are released from the damaged gland. As thyroid hormone stores are depleted, there is often a progression through a period of euthyroidism to hypothyroidism. Suppurative<unk>  is the result of an infection usually in the patients with preexisting thyroid disease (Hashimoto's<unk> , thyroid cancer, or multinodular goiter), immunosuppression, and congenital anomalies (pyriform sinus fistula). The diagnosis of<unk>  is usually made on the physical examination, thyroid function tests, thyroid ultrasound, iodine uptake, thyroglobulin, and thyroid peroxidase antibodies. Histopathological analysis is also helpful to differentiate<unk>  from other thyroid diseases. The treatment of<unk>  is usually symptomatic. Beta blockers are used for the symptoms of thyrotoxicosis and levothyroxine is helpful to improve the symptoms of hypothyroidism. NSAIDs are helpful in alleviating the pain in de Quervain's<unk>  and corticosteroids are specifically used in Riedel's<unk> . Antibiotics are usually reserved for the suppurative<unk> .
