Espectro clinicopatológico de las tiroiditis

clinical-pathological spectrum of thyroiditis comprises from the rare acute o suppurative thyroiditis as far as the rarest rieldel？s thyroiditis. also, subacute and silent thyroiditis (and it postpartum variant) are non common diseases, while autoimmune chronic thyroiditis or hashimoto？s disease results the most frequent thyroiditis and organ-specific autoimmune disorder, that is responsible for most part of hypothyroidism cases. effectively, in iodine-replete geographic areas, most persons with thyroid disorders have autoimmune disease. autoimmunity as primary phenomenon plays a transcendent role in etiopathogeny of chronic autoimmune thyroiditis, silent-postpartum thyroiditis and riedel？s thyroiditis and only a secondary role in subacute thyroiditis. probably, viral infections cause subacute thyroiditis, while pyogenic germs and fungus are responsible for suppurative thyroiditis. commonly, autoimmune and subacute thyroiditis are associated with thyroid dysfunction. it is known as ？destructive thyroiditis？, the thyroidal inflammatory process that is joined to destruction and transient thyrotoxicosis. usually, thyroid dysfunction in these cases adopt ？biphasic thyroiditis？ pattern, in which sequentially, transient thyrotoxicosis is followed by transient hypothyroidism and recovery. disorders with different etiopathogeny as subacute thyroiditis, silent thyroiditis and hashimoto？s thyroiditis are responsible of similarly physiopathologic phenomenons that originated biphasic thyroiditis. pain in the thyroidal gland is relevant in subacute and suppurative thyroiditis and, rarely is present in silent thyroiditis or in acute exacerbation of hashimoto？s thyroiditis. in most of the cases, it is possible to establish the diagnosis of thyroiditis through clinical history, thyroidal function tests, isotopic studies and ecosonography. thyroid fine needle biopsy resolves doubtful cases. this review about ？clinical-pathological spectrum of thyroiditis？, results from the synthesis
