(A) A chest computed tomographic scan showed a solid tumor of the right thyroid lobe and cystic disease of the left thyroid lobe. The tumor revealed calcification. The arrow shows the connection to the mediastinal tumor. (B) Fiber optic bronchoscopy finding shows the right upper bronchus (upper arrow) and the intermediate bronchus (lower arrow). A soft and erosive tumor was detected near the right upper bronchus. (C, D) A chest magnetic resonance image showed a cystic mass in the mediastinum that connected to the thyroid and compressed the esophagus. The tumor size was 11 × 6 × 4 cm in diameter.

3. Fig 2
(A) A macroscopic finding of the resected tumors. The mediastinal tumor was below the right lobe of the thyroid (approximately 8 cm in diameter). (B, C) Microscopic findings with hematoxylin & eosin stain: (B) a low-power view (×40) and (C) a high-power view (×200). Atypical columnar cells with irregular nuclei are proliferated and arranged in papillary or glandular structures. The nuclear grooving and inclusions are observed in the tumor cells. Marked stromal hyalinization and calcification are noted. The tumor cells were not invading the capsule nor were they exposed on the resected surface. All surgical margins are negative.
