Presentation
Presentation Lymphocytic thyroiditis may present with hyperthyroidism (early phase) or hypothyroidism (late phase), or it may present with a nodular or diffuse goitre. [surgwiki.com]

Nodules are clonal or polyclonal and are due to heterogeneous responses of follicular epithelium to TSH Exophthalmos of Graves disease is not present Also called nodular hyperplasia Nontoxic goiter: no hyperthyroidism present Epidemiology 90% of those [pathologyoutlines.com]
Workup
Otherwise incidental finding of thyroid nodules found on the inpatient service can be deferred to outpatient workup and management. [clinicaladvisor.com]
If any changes occur, then further workup is indicated. Evidence-based answers from the Family Physicians Inquiries Network [mdedge.com]
Although the risk of cancer is small, it is the main reason for workup of these lesions. Measurement of thyroid-stimulating hormone can identify conditions that may cause hyperfunctioning of the thyroid. [aafp.org]

Treatment
If repeat aspirations fail to provide an adequate specimen, close follow-up or surgery (particularly if the nodule is solid) should be considered.9 Treatment Options for Patients with Multinodular Goiters Several treatment modalities are available for [touchendocrinology.com]

Treatment The only treatment is surgical excision through a skincrease incision. [surgwiki.com]
This can be done with: Ultrasound Thyroid scan Barium swallow X-ray Treatment Nontoxic goiters usually grow very slowly. They may not cause any symptoms. In this case, they do not need treatment. [winchesterhospital.org]
Prognosis
[…] but may be seen incidentally CT may be useful for fully characterising the extent of substernal (retrosternal) goitre an enlarged and heterogeneous thyroid gland suggests the diagnosis, which is confirmed by ultrasound or scintigraphy Treatment and prognosis [radiopaedia.org]
Follicular cancer occurs in an older age group (40–60 years), arises as a single tumour, metastasises by the bloodstream, and has a worse prognosis than papillary cancer, with 10 year survival rates around 75%. [surgwiki.com]
Support Groups: Expectations (prognosis): A goiter is a benign (harmless) process. A simple goiter may disappear on its own, or may become large. [uclahealth.org]
Etiology
Pathophysiology The histopathology varies with the etiology and duration of the goiter. [ocw.tufts.edu]
Etiology Multinodular goiter (MNG) loci have been identified on chromosome 14q and on chromosome Xp22 and 3q26. Germline mutations in DICER1 (chromosome 14q31) have been found in familial MNG-1, with and without ovarian Sertoli-Leydig cell tumors. [unboundmedicine.com]
Abstract: Iodine deficiency is the most important etiological factor for euthyroid endemic goiter. However, family and twin pair studies also indicate a genetic predisposition for euthyroid simple goiter. [edoc.mdc-berlin.de]

Epidemiology
Epidemiology The most common cause of pediatric goiter in the United States is chronic lymphocytic thyroiditis. The prevalence of goiter in the United States is 3–7%, although the incidence is much higher in regions of iodine deficiency. [unboundmedicine.com]
Epidemiologically ascertained risk factors are ionizing radiation, the presence of thyroid adenoma, multinodular goiter (MNG) and family history of thyroid cancer, and personal history of goiter or thyroid nodule. [iasj.net]

Prevention
Prevention: The use of iodized table salt prevents endemic goiter. [uclahealth.org]
This thoroughly updated edition includes an introduction to risk assessment and screening and results of recent clinical trials and their implications for treatment and prevention. [books.google.com]
The use of iodized salt in the United States prevents a lack of iodine in the diet. [medlineplus.gov]
The efficacy of levothyroxine suppressive therapy in preventing recurrence of goiter growth after partial thyroidectomy is less clear. [touchendocrinology.com]
Management Iodine supplementation is perhaps the simplest and cheapest of all remedies and it prevents a condition that has devastating consequences; it is sobering that iodine deficiency still persists. [enetmd.com]
