Epstein-Barr Virus Associated Lymphoepithelioma-Like Carcinoma of the Esophagogastric Junction and Stomach: A Case Report and Review of the Literature

A 63-year-old man was admitted to our hospital with 2 months history of dysphagia. Endoscopic examination revealed an ulserovegetan tumor starting from distal esophagus and extending to the cardia. Pathological examination of the biopsy revealed an epithelial malignant tumor without further classification. The patient underwent a surgery following neo-adjuvant chemotherapy with oxaliplatin, 5-fluorouracil and leucoverin (FOLFOX) regimen. Postoperative pathological analyses showed high grade EBV-associated lymphoepithelioma-like carcinoma of the gastroesophagial junction and stomach. After surgery, we planned to administered 6 cycles of FOLFOX regimen as an adjuvant treatment. Lymphoepithelioma-like gastric carcinoma is a rare type of gastric carcinoma and has distinct clinic-pathologic characteristics, including male predominance, preferential location in the gastric cardia, lymphocytic infiltration, a lower frequency of lymph node metastases and more favorable prognosis. Surgical resection is the most effective treatment modality. Chemotherapy may be considered for patients who have high risk factors.
