Rare Case of Squamous Cell Cancer - Mixed Neuroendocrine Neoplasm in the tubular Esophagus (MiNEN) discovered by Endoscopic Submucosal Dissection of the entire Tumor.

Abstract

Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are rare in the gastrointestinal tract.We report the case of a patient in whom complete endoscopic resection of a tumorous lesion in the tubular esophagus, initially diagnosed as squamous cell carcinoma (SCC) led to the diagnosis of SCC-MiNEN, which changed the patient´s treatment course.With improvements in endoscopic techniques, we advocate resection of small malignant lesions in the gastrointestinal tract for both curative and diagnostic reasons.
