Endoscopic findings of primary follicular lymphoma.

ABSTRACT

A 79-year-old female with benign past medical history presented to the gastroenterology clinic complaining of long-standing symptoms of dyspepsia. Esophagogastroduodenoscopy showed nodular smooth mucosa in the second part of the duodenum. The morphologic and immunophenotypic findings were consistent with low-grade follicular lymphoma. The purpose of this manuscript is to educate the reader on this unusual finding that is pathognomonic for gastrointestinal lymphoma.
