Ninety-nine cases of adenosquamous carcinoma of the esophagus have so far been reported in Japan. A 60-year-old male was admitted with a history of dysphagia. Barium roentogenography and endoscopy revealed an erosive lesion in the middle portion of the esophagus, dignosed as a superficial esophageal carcinoma, and a large submucosal tumor in the cardial portion of the stomach. After subtotal resection of the thoracic esophagus and partial gastrectomy, an esophagogastrostomy was perfomed via the thoracic route. Histological examination of the resected specimen showed that the lesion in the middle portion of the esophagus was a moderately differentiated adenosquamous carcinoma invading into the submucosa. Histological examination of the tumor in the cardial portion of the esophagus, which measured 9.5×8.2×8.0 cm in size, revealed that it was a poorly differentiated adenosquamous carcinoma representing metastasis of the esophageal carcinoma to the gastric wall. In all cases, excluding our present case, of intramural metastasis of esophageal carcinoma to the gastric wall, the primary lesion in the esophagus was a squamous cell carcinoma. Ours was a case of intramural metastasis of an esophageal adenosquamous carcinoma to the gastric wall.
