Recurrence of diffuse large B-cell lymphoma recurring in the ileum 10 years after complete remission: A case report

An 88-year-old female was referred to our hospital because she was anemic and was experiencing general fatigue. Eleven years ago, CT-guided lymph node biopsy revealed diffuse large B-cell lymphoma for which she underwent R-CHOP therapy. Ten years ago, she was judged to be in complete remission using PET-CT. At the time of her current visit to our hospital, her serum hemoglobin was 6.2 g/dL, and abdominal CT scan showed an ileal tumor and multiple swollen lymph nodes in the peritoneal space. Colonoscopy revealed a tumor of the terminal ileum, and forceps biopsy was performed. Pathologically, the tumor was diagnosed as diffuse large B-cell lymphoma. As she was elderly, chemotherapy was not performed, and she died 54 days after her visit to our hospital.
