Abstract
This case report highlights an uncommon presentation of small bowel lymphoma as gastrointestinal bleeding in an 87-year-old female with a history of ulcerative colitis. Despite non-specific symptoms and negative findings on upper endoscopy and colonoscopy, ileoscopy revealed a distal ileal mass with a solitary non-bleeding ulcer, confirmed by biopsy as diffuse large B-cell lymphoma (DLBCL). The patient opted for palliative management. Small intestinal lymphomas, particularly DLBCL, pose diagnostic challenges due to their varied presentations. Timely detection is crucial for optimal outcomes, emphasizing the importance of prompt utilization of diagnostic methods in suspected cases.
