An Endoscopic Ultrasound Diagnosis of a Rare Cause of Pancreatic Body Mass Demonstrating the Transformation to Large B-Cell Lymphoma.

ABSTRACT

The presence of lymphoma in the gastrointestinal tract is most frequently manifested in the stomach and intestines. Pancreatic lymphomas consist of only 0.5% of all pancreatic neoplasms. In this case, we present a patient afflicted by follicular lymphoma with pancreatic involvement. To monitor the progression of this patient's lymphoma, endoscopic ultrasound was used to observe its transformation to large B-cell lymphoma and guide therapy.
