An asymptomatic 83-year-old man was found to have a right intrathoracic tumor. Computed tomography demonstrated a soft-tissue density mass measuring 55 × 25 × 22 mm adjacent to the right anterior chest wall. At surgery, the tumor was found to adhere to the diaphragm and right lung, contiguous with the mediastinal fat tissue. Histology of the resected specimen demonstrated proliferation of spindle and sarcomatous cells with multinucleated giant cells. Thus the tumor was diagnosed as undifferentiated thymic carcinoma and was considered to have arisen from ectopic thymic tissue. At 2 years postoperatively, the patient had no evidence of recurrence.
一名83岁无症状男性被发现患有右胸内肿瘤。计算机断层扫描显示，在右前胸壁附近有一个大小为55×25×22mm的软组织密度肿块。手术中发现肿瘤与膈肌和右肺粘连，与纵隔脂肪组织相邻。切除标本的组织学检查显示梭形细胞和肉瘤样细胞增生，并伴有多核巨细胞。因此，该肿瘤被诊断为未分化胸腺癌，被认为起源于异位胸腺组织。术后2年，患者无复发迹象。
