  Fig. 1. (A) Computed tomography (CT) of the chest shows the extremely thickened pleura along the left lobe. (B) Positron emission tomography–CT shows fluorodeoxyglucose uptake in the left pleural thickening areas.

  Fig. 2. Histopathological sections showing tumor cells with glandular and papillary, cord-like structures (A) and a hobnail-like appearance of tumor cells with irregular and hyperchromatic nuclei resembling malignant mesothelioma (B). Immunohistochemical evaluation demonstrates the tumor cells to be positive for thyroid transcription factor-1 (C) and negative for calretinin (D).
