Core Tip
Core Tip: Appendiceal bleeding is extremely rare. We reported a case of a young man with hematochezia diagnosed with appendiceal bleeding via colonoscopy and computed tomography angiography. Laparoscopic appendectomy confirmed vascular malformation as the cause. Through literature review, we summarized clinical manifestations, causes, and treatment options, aiming to provide references for clinicians. Endoscopic hemostasis is feasible but carries a risk of appendicitis. Appendectomy is considered the definitive and reliable treatment, especially after failure of conservative treatment or endoscopic management, as it prevents recurrence.
