Although much progress has been made in the detection and the early treatment of esophageal cancer, the prognosis is still limited, and mortality remains very high. The most common histological types of esophageal cancer are squamous cell carcinoma, and, respectively, adenocarcinoma. Lately, there has been an accelerated increase in the incidence of adenocarcinoma, in the context of increased prevalence of gastro-esophageal reflux disease and obesity, but also of the current alimentary diet, especially in developed countries. The esophagus has its anatomical features. Moreover, it is located topographicallyin a complex cervico-thoraco-abdominal area, unique for a viscus. From the clinical point of view, the onset of symptoms of esophageal cancer is insidious. For these reasons, special attention should be pain in the early detection and differentiation of this neoplasm from other pathologies. These pathologies are very varied and may comprise other esophageal diseases, neighborhood pathologies such as cervical, thoracic, abdominal, systemic pathologies (immunologic, infectious) or other pathologies such as the oro-maxillo-facial, oculo-orbital, vascular, muscular, and cutaneous ones.
