This is a case of a 72-year-old male whose chest computed tomography (CT) revealed a 2.0 x 1.6 cm anterior mediastinal solid tumor during follow-up of an abnormal shadow of the lung. The tumor increased its size during preoperative follow-up, and multilocular cyst was also observed. Radical thymectomy was performed, and histopathologically the tumor was diagnosed as thymic basaloid carcinoma. Thymic basaloid carcinoma is a rare tumor and is often associated with multilocular thymic cyst. There are only 32 cases reported both locally and internationally. Surgical resection is the general treatment for this disease. Adjuvant radiotherapy can be considered in cases of incomplete resection and invasive tumor. In our case, no recurrence of the tumor was noted 12 months post-operative. Generally, the malignancy of thymic basaloid carcinomas are regarded as low-grade compared with other thymic carcinomas, however, since mortality and recurrence have been reported, careful follow-up is required.
这是一例72岁男性患者，其在肺部异常阴影随访期间，胸部计算机断层扫描（CT）显示前纵隔有一个2.0×1.6 cm的实性肿瘤。肿瘤在术前随访期间增大，还观察到多房性囊肿。进行了根治性胸腺切除术，组织病理学诊断该肿瘤为胸腺基底细胞癌。胸腺基底细胞癌是一种罕见肿瘤，常与多房性胸腺囊肿相关。国内外仅报道了32例。手术切除是该病的主要治疗方法。对于切除不完全和肿瘤浸润的病例可考虑辅助放疗。在我们的病例中，术后12个月未发现肿瘤复发。一般来说，与其他胸腺癌相比，胸腺基底细胞癌的恶性程度被认为较低，然而，由于有死亡率和复发的报道，仍需要密切随访。
