Epstein-Barr Virus-Positive Lymphoepithelioma-Like Carcinoma in Celiac Disease

Lymphoepithelioma-like carcinoma (LELC) is a rare lymphoproliferative malignancy that has been described in many organs over the years. LELC in the duodenum has rarely been described in literature. This article aims to present a rare cause of melena in a young man and the diagnostic challenge that ensued to throw more light on this rare disease. In this article, we describe a 43-year-old man who presented with melena and weight loss and was subsequently diagnosed with LELC after multiple endoscopic biopsies. The patient was also found to have celiac disease in association with his LELC.
