Case report: esophageal metastasis from breast carcinoma presenting as achalasia.

Metastatic breast carcinoma to the esophagus most often presents with a mid-esophageal stricture. Involvement of the gastroesophageal junction by breast carcinoma is distinctly unusual. The authors report the case of a 78-year-old woman who presented with clinical and radiologic features of achalasia secondary to breast carcinoma, metastatic to the gastroesophageal junction. Metastatic breast cancer to the gastroesophageal junction should be added to the list of conditions mimicking achalasia.
