A Chest computed tomography imaging of the primary tumor (arrow). B Pathological examination of the primary tumor reveals thymic squamous cell carcinoma. Hematoxylin and eosin staining; original magnification ×50 and ×200 (inset). C–I On immunohistochemical staining, the primary tumor is positive for PAX8 (C), CD5 (D), and c-KIT (E), while intratumoral lymphocytes are negative for TdT (F) and CD1a (G). The primary tumor demonstrates low expression of p53 (H) and positive staining for programmed death-ligand 1 (I). Original magnification ×200
