[Epidermoid carcinoma of the esophagus secondary to achalasia]

We present the case of a 78-year-old patient who developed epidermoid carcinoma of the esophagus 5 years after Haller myotomy for achalasia, which produced an improvement in the clinical symptoms, as well as in the radiological, endoscopic and manometric manifestations. The appearance of carcinoma after a moderate period of time underlines the need for continued periodic follow-up of these patients.
