title: Simultaneous Esophageal Squamous Cell Carcinoma and Adenocarcinoma: A Case Report.
abstract: Esophageal squamous cell carcinoma is a rather common cancer in northern Iran. Incidence of adenocarcinoma of esophagus has an increasing trend in Iran. Co-existence of both cancers in one patient is very rare. We report a middle age woman from northern Iran with a typical presentation of esophageal cancer, who was found to have a dual esophageal cancer. The disease was found in the advanced stage with pulmonary metastasis at the presentation. Palliative chemo-radiotherapy induced partial clinical response.
