Tumor neuroendócrino esofagiano: um relato de caso raro

Abstract

Esophageal neuroendocrine tumor (NET-e) is considered the rarest gastrointestinal tract neuroendocrine tumor (NET-TGI), with a prevalence of 4.9% amongst the NET-TGI, varying according to the geographic region. NET-e has an aggressive behavior and fast dissemination, so, early diagnosis is very important. Diagnosis can be a challenge because there are no specific symptoms. Patients may either be asymptomatic or they may present a range of symptoms, like dysphagia, chest pain, weight loss, odynophagia and digestive bleeding. Upper gastrointestinal endoscopy is a diagnostic tool that allows visualization of the tumor and obtainance of material for histopathological analysis. NET-e is characterized by a single polypoid lesion in the distal esophagus. Once diagnosed, it is important to follow up with an oncologist to initiate specific treatment.
