Uniportal video-assisted thoracoscopic surgery for complex mediastinal mature teratoma: A case report

Figure 1 Enhanced chest computed tomography scan before surgery. A: In the coronal mediastinal window, the presence of a right hilar enlargement.an emerging cavity with high-density consolidation, high-density opacities occupying the right upper and middle lobe, diffuse high-density opacities with shadows and stripes, irregular soft tissue of mixed density in the anterior right upper mediastinum, and consolidation with cavitation and calcification adjacent to the mediastinum are shown; B: In the mediastinal window; C: In the lung window.

Figure 2 The images of surgical specimen histopathology. Surgical specimen’ largest diameter was 10 cm. A: The macroscopical image of the mass; B: Cut of the mass shows sebaceous material; C: Image of the cartilage tissue of the mass.

Figure 3 Hematoxylin and eosin staining of teratoma. Histopathologic analysis revealed mature tissues, cartilage tissue and sebaceous material with the mass. A: Lower magnification (40 ×, scale bar = 250 μm) shows cartilage tissue; B: Loupe image of the tumor shows mature tissues (100 ×, scale bar = 100 μm); C: Higher magnification (200 ×, scale bar = 33 μm) shows sebaceous material.
