Abstract
We present the case of a 56-year-old male with cecal involvement of non-Hodgkin's lymphoma (NHL), whose tumor was refractory to multiple chemotherapy regimens and ultimately resulted in significant local complications due to tumor erosion, leading to considerable morbidity. NHL is the most common hematologic cancer with many subtypes of disease, with diffuse large B-cell lymphoma (DLBCL) being the most common. Extra-nodular presentation in the gastrointestinal tract is typical in many cases; however, the involvement of the colon is rare. This case details a patient with extra-nodal involvement of the cecum. The patient initially presented with an enlarging neck mass. This report highlights the importance of evaluating extra-nodular disease.
