Papillary thyroid carcinoma with lung metastasis arising from dyshormonogenetic goiter: a case report.

Prior radiation exposure is the best known risk factor for thyroid cancers, and papillary thyroid carcinoma (PTC) may arise from dyshormonogenetic goiter. A 17-year-old female patient was admitted to the department of chest diseases with respiratory symptoms. The patient had undergone a thyroid surgery for goiter at the age of 9. A bilateral nodular opacity was detected by radiological examination. The histopathologic examination of the specimen obtained from computed tomography guided trucut biopsy was diagnosed as PTC. We present a very rare case of PTC with lung metastasis that had undergone subtotal thyroidectomy due to dyshormonogenetic goiter eight years ago.
