食管肉瘤临床少见,作者等在近13年内手术治疗食管癌502例(贲门癌除外),仅发现1例肉瘤,术前尚误诊为纵隔肿瘤,现报告如下。患者女性,40岁,因进食受阻半月余且吐粘液而入院。体格检查无异常阳性体征。食管钡餐检查示食管下段钡剂充盈缺损约4.5cm,粘膜尚光整,周围见有明显软组织块影。X线胸片显示右后纵隔中下部有10×9.5cm大小肿块影,界限清楚,密度均匀,无钙化;食管下段明显受压,管壁毛糙,柔 Esophageal sarcoma is rarely seen clinically. The authors treated 502 cases of esophageal cancer (excluding cardiac cancer) in the past 13 years. Only 1 case of sarcoma was diagnosed. The preoperative tumor was still misdiagnosed as a mediastinal tumor. The report is as follows. The female patient, 40 years old, was admitted to hospital because she had eaten for more than half a month and had spit mucus. Physical examination showed no signs of abnormal positive signs. Esophageal barium meal examination showed that the esophageal barium filling defect was about 4.5cm, the mucous membrane was still smooth, there were obvious soft tissue shadows around. The X-ray showed a mass of 10×9.5 cm in the middle and lower right posterior mediastinum with clear boundaries, uniform density, and no calcification; the lower esophagus was significantly compressed, and the wall of the tube was rough and soft.
