Abstract
This case report presents the clinical findings, diagnostic evaluation, and treatment options for a 71-year-old female patient with a medical history of hypertension, dyslipidemia, and recurrent urinary tract infections. The patient presented with chronic abdominal pain as the sole symptom. Despite normal laboratory investigations, esophagogastroduodenoscopy and ileocolonoscopy were performed. Biopsies were obtained from the duodenum and histopathological analysis confirmed a diagnosis of duodenal-type follicular lymphoma. This rare condition typically presents with minimal clinical symptoms and has a favorable prognosis. Treatment options for duodenal-type follicular lymphoma include a watch-and-wait strategy, rituximab monotherapy, and radiotherapy.
