Hashimoto\'s thyroiditis presenting as a single toxic adenoma

Abstract

Background: Hashimotochr('39')s thyroiditis can be present with a localized palpable nodule though presentation as a hyperfunction "nodule" is extremely rare. The first case of Hashimotochr('39')s thyroiditis and hot nodule was reported in 1971 by warner. Case Presentation: We reported a 26-year-old hypothyroid woman in Hashimotochr('39')s thyroiditis background with a hyperactive thyroid nodule in both 99mTc and I131scintigraphy. The nodule disappeared after eight months sufficient thyroid hormone replacement therapy. Conclusion: Toxic adenoma in hypothyroid patients can be resolved after the thyroxin replacement therapy.
