title: Case report of achalasia secondary to a lung carcinoma of the mediastinal type.
abstract: Pseudo- or secondary achalasia may mimic primary achalasia upon radiological examination and may be difficult to diagnose. It is usually due to a cancer or metastases involving the gastroesophageal junction. We present the case of a 53-year-old woman with recent onset of dysphagia, and with typical findings suggesting primary achalasia. We found a 4-cm mediastinal tumor invading the lower esophagus, which was proven to be a metastasis from a lung carcinoma. The patient was treated with surgery, chemotherapy and radiotherapy. In patients with a new onset of achalasia symptoms, keeping in mind the possibility of an underlying cancer is important.
