Figure legends
Figure 1. Radiological findings at admission to our hospital. Chest X-ray showed decreased radiolucency in the right upper-peripheral, middle and lower lung fields with dullness at the right costophrenic angle (A). Chest computed tomography shows diffuse thickening of the right pleura with effusion (B, C).
Figure 2. Percutaneous pleural biopsy specimen shows (A, B) no cornification in non-Sq NSCLC; (C), positive staining for Ber-EP4 (carcinoma marker); (D) negative staining for calretinin (mesothelioma marker). (A: hematoxylin/eosin staining, 4× original magnification; B–D: 20× original magnification.)
Figure 3. Chest computed tomography shows improved pleural disease after cytotoxic chemotherapy (A, B: after two cycles of cisplatin and pemetrexed) (C, D: after 29 cycles of maintenance pemetrexed, leading to a complete response).
Figure 4. Proton emission tomography, two months after discontinuing maintenance pemetrexed, shows no enhanced signal throughout the body (A). Chest X-ray after 51 months (B) and chest computed tomography at 54 months after discontinuing PMT show no recurrence (C, D).
