Abstract

Papillary thyroid carcinoma and primary lung cancer have vastly different treatment approaches and prognosis. If lung mass is found in patients with papillary thyroid carcinoma, we have to be aware of the possibility of primary lung cancer especially when the lesion is not iodine-avid, or is not typical to metastatic thyroid carcinoma, or serum thyroglobulin is not elevated. Here we present two cases of non-small cell lung cancer masquerading as metastatic papillary thyroid carcinoma and think of the approach of the lung mass which is found in patients with papillary thyroid carcinoma.
