Introduction
Neuroendocrine tumor covers a wide range of neoplasms that originate in the neuroendocrine cells which spread throughout the body.Carcinoid tumor, and neuroendocrine tumor are low-grade malignant tumors, their growth is slow, and mainly in the gastrointestinal epithelium. Esophageal adenocarcinoma tumor is a big problem in esophageal cancer. Combined esophageal adenocarcinoma and carcinoid tumor both as primary tumors is very rare[1].
Neuroendocrine tumors of the esophagus are derived from the diffuse neuroendocrine system in the gastrointestinal tract. Neuroendocrine tumors in the esophagus can be distinguished from other mesenchymal tumors by immunostaining for synaptophysin and chromogranin-A. Both carcinoid of the esophagus and adenocarcinoma of the esophagus are malignant tumors and considered to have a specifi c molecular pathogenesis. This paper presents a rare case diagnosed as carcinoid of the esophagus concomitant with an adenocarcinoma of the esophagus, a review of the literature is also presented here.
