Background. Coincidence of a primary lung cancer and pulmonary metastases from other malignancies should be kept in mind at the time of pulmonary resection. Case. Chest CT revealed a small pulmonary nodule (5 mm) in the right upper lobe and swelling of the interlobar lymph node (20 mm) in a 71-year-old man. He underwent resection of the right upper and middle lobes with lymph node dissection. As expected, pathological diagnosis of the lung nodule and the lymph node revealed adenocarcinoma. In addition to the above lesions, multiple microscopic pulmonary metastases of thyroid cancer were found at the time of postoperative detailed histological investigation. No primary thyroid lesion was detected by postoperative examination. Conclusion. Through pathological examination revealed an otherwise undetectable coincident second malignancy.
