Dieulafoy's Disease Causing Appendiceal Hemorrhage: A Case Report.

Dieulafoy's disease is an uncommon but potentially life-threatening vascular anomaly characterized by a dilated, aberrant submucosal artery that causes mucosal erosion and significant gastrointestinal bleeding. While most frequently located in the proximal stomach, Dieulafoy's lesions can occur anywhere in the GI tract. Involvement of the appendix is exceedingly rare and may pose a diagnostic challenge due to the inconspicuous nature of the lesion and its inaccessibility via routine endoscopy. We present a rare case of appendiceal Dieulafoy's disease manifesting as isolated lower gastrointestinal bleeding.
