Acute Diverticulitis as a form of Presentation of Follicular Lymphoma of the Colon

Follicular lymphoma is the second most-common subtype of non-Hodgkin lymphoma, after Diffuse large B-cell lymphoma. Primary lymphomas of the gastrointestinal tract are rare, with secondary intestinal involvement being more common. We present the case of a 68-year-old male patient who was diagnosed with colonic follicular lymphoma during the study for recurrent acute diverticulitis.
