Secondary achalasia due to submucosal invasion of esophageal squamous cell carcinoma (SCC) is a very rare condition. Here, we report a case of secondary achalasia diagnosed after distal esophagectomy, initially mistaken as primary achalasia. A 51-year-old man presented with progressive dysphagia for 2 months and mild weight loss. A barium swallow study, endoscopy, and manometry showed typical findings of primary achalasia. Pneumatic dilatation was performed, but esophageal perforation occurred as a complication. During surgical repair, no abnormalities around distal esophagus were found, and intraoperative esophageal biopsy revealed only inflammatory cells. During the following 8 months, the patient suffered from dysphagia caused by recurrent esophageal obstruction several times although of repeated balloon dilatation and esophageal stent insertion. Finally, he received a distal esophagectomy. The postoperative pathology revealed SCC at the distal esophagus and esophagogastric junction.
