QUERA, Rodrigo et al. Rectal diffuse large B cell lymphoma appearing after immunosuppression for ulcerative colitis. Report of one case. Rev. méd. Chile [online]. 2017, vol.145, n.10, pp.1342-1348. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872017001001342.

Primary colorectal lymphoma is a rare form of presentation of gastrointestinal tract lymphomas. Inflammatory bowel disease and its treatment are risk factors for its development. We report a 47-year-old male patient with Ulcerative Colitis of two years of evolution, treated initially with azathioprine and later on with infliximab. Due to a relapse in symptoms after the second dose of infliximab, a new coloncoscopy was performed showing a rectal ulcerative lesion, corresponding to a large cell Non-Hodgkin's Lymphoma. The patient was successfully treated with RCHOP chemotherapy (Rituximab cyclophosphamide doxorubicin vincristine prednisone). He is currently in disease remission.
