Colorectal adenocarcinoma is the neoplastic proliferation of glandular tissue in the distal gastrointestinal system and can be managed using surgical resection, novel chemotherapeutic regimens, and radiation therapy. Epstein-Barr virus (EBV) is a common double-stranded DNA virus that has the potential to transform B-cells into lymphoproliferative disorders given the presence of particular conditions such as immunocompromised and chronic inflammatory states. Colorectal cancer is one of the most common malignancies worldwide; however, the additional finding of EBV-positive lymphoma in a patient with a history of colorectal malignancy is uncommon, and this phenomenon has not been thoroughly explored. This report investigates the association between rectal adenocarcinoma and EBV-positive large B-cell lymphoma in an 87-year-old Caucasian male residing in the United States and explores possible causes for this occurrence.
