Subacute lymphocytic thyroiditis may occur at any age and is more common in females. A variant of subacute lymphocytic thyroiditis occurs postpartum: postpartum thyroiditis. Both of these entities can be considered subtypes of Hashimoto's thyroiditis and have an autoimmune basis. Anti-thyroid antibodies are common in all three and the underlying histology is similar. [1][2] This disorder should not be confused with de Quervain's thyroiditis which is another form of subacute thyroiditis. SymptomsSubacute lymphocytic thyroiditis features a small goiter without tenderness. This condition tends to have a phase of hyperthyroidism followed by a return to a euthyroid state, and then a phase of hypothyroidism, followed again by a return to the euthyroid state. The time span of each phase can vary; however, each phase usually lasts 2–3 months.[1] DiagnosisSubacute lymphocytic thyroiditis can only be diagnosed correctly by taking a radioactive iodine uptake test (RAIU) test.[1][3] During both the hyperthyroid and hypothyroid phases, radioiodine uptake is decreased.[4] This situation contrasts greatly with the elevated iodine uptake found in patients with Graves' disease.[1] TreatmentTreatment is based on symptoms. Beta-blockers relieve rapid heart rate and excessive sweating during the hyperthyroid phase.[4] References1. ^1 2 3 Thyroiditis: Differential Diagnosis and Management, American Family Physician, February 15, 2000 {{Endocrine pathology}}2. ^{{DorlandsDict|eight/000108754|Subacute lymphocytic thyroiditis}} 3. ^Description of Radioactive Iodine Uptake Test, WebMD.com, August 14, 2008 4. ^1 [https://www.nlm.nih.gov/MEDLINEPLUS/ency/article/000388.htm NIH Medline Plus] 1 : Thyroid disease |
