A 36-year-old man, who had never been detected abnormalities on an annual chest X-ray check up, presented with a sudden onset of right-sided chest pain and fever. Contrast-enhanced computed tomography showed an anterior mediastinal mass with necrosis or hemorrhage and right pleural effusion. Neither computed tomography-guided biopsy nor video-assisted thoracic surgery (VATS) yielded definitive histological diagnosis due to insufficiency of the sample. For diagnosis and treatment, we performed thymectomy. Histopathologically, the tumor was almost entirely necrotic with few viable tumor cells on periphery. A diagnosis of B2 thymoma was rendered.
一名36岁男性，既往年度胸部X线检查从未发现异常，此次突发右侧胸痛和发热。增强计算机断层扫描显示前纵隔肿块伴坏死或出血以及右侧胸腔积液。由于样本不足，计算机断层扫描引导下活检和电视辅助胸腔镜手术（VATS）均未得出明确的组织学诊断。为明确诊断和进行治疗，我们实施了胸腺切除术。组织病理学检查显示，肿瘤几乎完全坏死，周边仅有少量存活的肿瘤细胞。诊断为B2型胸腺瘤。
