According to the Global Cancer Observatory, 3.1% of new cancer cases consists of esophageal cancer and 5.5% of deaths was due to esophageal cancer.

We present a case of 33-year old male admitted due to progressive dysphagia. He underwent esophagogastric resection and histopathologic studies revealed a mixed neuroendocrine- non-neuroendocrine tumor. He received adjuvant chemotherapy. On mid-cycle evaluation, the patient showed no evidence of disease recurrence.
