Esophageal carcinosarcoma is a rare malignant tumor composed of both carcinomatous and sarcomatous elements. We report a case of esophageal carcinosarcoma in a 56-year-old woman with dysphagia. Esophageal ulcerative tumors were detected by endoscopy and resected by thoracoscopic esophagectomy. Carcinosarcoma was confirmed by the presence of both carcinomatous and sarcomatous tumor components. On immunohistochemistry, the sarcomatous area was positive for keratin staining, while the sarcomatous area was positive for vimentin staining. The tumor reportedly had a better prognosis than SCC of the esophagus, especially in terms of survival rate. The patient’s disease was classified as ypT3N0M0, ypStage II. No definitive diagnosis was made preoperatively. We report this case along with a review of the literature.

表现为局灶性溃疡性病变的胸段食管癌肉瘤

食管癌肉瘤是一种罕见的恶性肿瘤，由癌性和肉瘤性成分共同组成。我们报告了一名 56 岁女性吞咽困难的食管癌肉瘤病例。内镜检查发现食管溃疡性肿瘤，胸腔镜食管切除术切除。通过癌性和肉瘤性肿瘤成分的存在证实了癌肉瘤。免疫组化显示，肉瘤区角蛋白染色阳性，而肉瘤区波形蛋白染色阳性。据报道，该肿瘤的预后优于食管鳞状细胞癌，尤其是在存活率方面。该患者的疾病被分类为 ypT3N0M0，ypStage II。术前未明确诊断。我们在查阅文献的同时报告了这个案例。
