抄録

A 60-year-old man with a three-month history of vague symptoms of dysphagia was admitted to Urawa Municipal Hospital on April 8, 1992. Upper gastrointestinal barium examination revealed a bulky mass (13×7×6 cm) occupying the upper half of the stomach. Endoscopy revealed a large pedunculated tumor arising from the abdominal esophagus and suspended into the stomach. Lugol staining method disclosed multiple superficial lesions on the middle and lower third of the esophagus. Biopsied specimens revealed spindle-shaped sarcomatous cells in the bulky mass and multifocal squamous cell carcinoma in the esophagus. Thoracic esophagectomy with lymph node dissection and gastric tube reconstruction was performed. Based on immunohistochemical and electron microscopic findings, the tumor was diagnosed as spindle cell carcinoma (pseudosarcoma). The involvement of squamous cell carcinoma in pericardiac and celiac lymph nodes was observed. After postoperative adjuvant chemotherapy using cisplatin (125mg/body), the patient was discharged on 39th postoperative day. Fourteen months have passed without recurrence since the operation.
