Lymphoepithelioma-like gastric carcinoma (LELGC) constitutes 1-4% of all gastric carcinomas and gastrointestinal involvement in leukemia can be present in up to 25%, being more common in acute than chronic leukemia, affecting most frequently the stomach, ileum, and proximal colon. LELGC is usually associated with a better prognosis than other gastric carcinomas, generally presenting with low T and N stages. The reports of chronic lymphocytic leukemia (CLL) involving infiltration of the gastrointestinal tract are relatively rare in the literature, and the estimated incidence ranges from 5.7% to 25%. We present the case of a 77-year-old female, on surveillance by a known CLL that was diagnosed with gastric carcinoma on an esophagogastroduodenoscopy (EGD) performed for epigastric pain. A subtotal gastrectomy was performed and the surgical specimen revealed simultaneous involvement of the stomach by LELGC and CLL. To the best of our knowledge, this is the first reported case of a LELGC and CLL simultaneously involving the stomach.
