Primary adenocarcinoma of the upper esophagus: A rare presentation

INTRODUCTION AND IMPORTANCE: Cervical esophageal cancer is a rare condition, accounting for less than 5 % of all esophageal malignancies. CASE PRESENTATION: We report here a case of a 65-year-old female patient with a history of breast cancer diagnosed in 1985 treated with surgery, adjuvant chemotherapy, and radiotherapy. This woman presented with chronic organic high dysphagia to both solid and liquids and food impaction. Gastroscopy showed a stenosing esophageal budding tumor located at 20 cm from the incisors. Histological examination showed a well-differentiated adenocarcinoma. CLINICAL DISCUSSION: The diagnosis of primary adenocarcinoma of the upper esophagus is based on a combination of clinical presentation, imaging studies, and confirmed by histopathological examination. Upper digestive endoscopy is the gold standard for the diagnosis of esophageal cancer. CONCLUSION: Primary adenocarcinoma of the upper esophagus is a rare form of esophageal cancer.
