We report a case of basaloid carcinoma originated from the wall of a large thymic cyst, which is a very rare subtype of thymic carcinoma. A 60-year-old man admitted at our hospital due to dyspnea with pericardial and left thoracic effusion on chest X-ray. A computed tomography and a magnetic resonance imaging demonstrated a large anterior mediastinal cyst and a small mass lesion on the part of the wall. We performed as possible as resection of the thymic cyst and the tumor with median sternotomy. The pathological diagnosis was a thymic basaloid carcinoma originated from the wall of a thymic cyst, which classified into a low-grade histology in thymic carcinoma. He has been well with no evidence of recurrence for three years since operation followed by a post-operative radiation therapy (total 57 Gy) to the residual tumor and mediastinum.
我们报告一例起源于巨大胸腺囊肿壁的基底样癌，这是一种非常罕见的胸腺癌亚型。一名60岁男性因呼吸困难入院，胸部X线显示有心包积液和左侧胸腔积液。计算机断层扫描和磁共振成像显示前纵隔有一个巨大囊肿，囊肿壁上有一个小肿块病变。我们通过正中胸骨切开术尽可能切除胸腺囊肿和肿瘤。病理诊断为起源于胸腺囊肿壁的胸腺基底样癌，在胸腺癌中属于低级别组织学类型。自手术以来，他接受了针对残留肿瘤和纵隔的术后放射治疗（总计57 Gy），术后三年情况良好，无复发迹象。
