Abstract
This report presents a case of Dieulafoy's lesion (DL), a rare and serious gastrointestinal condition, which occurred unusually in a duodenal diverticulum and highlights the diagnostic and management complexities associated with it. A literature review of six similar cases revealed commonalities in presentation, diagnosis, and management, emphasizing the complexities in identifying and handling this rare manifestation of DL. The findings emphasize the need for clinical vigilance and further research into optimizing strategies for diagnosing and managing this rare condition.
