description BACKGROUND: This case report highlights the exceptional rarity of appendix duplication in adults, a condition that closely mimics appendiceal tumors, posing diagnostic challenges. The novelty of this case lies in its presentation of a Type A duplication, emphasizing the diagnostic intricacies involved in distinguishing it from other pathologies. CASE PRESENTATION: We present the case of a 69-year-old male with a history of hypertension, hyperuricemia, and duodenal gastric ulcer, who presented with a positive occult blood test. Lower gastrointestinal endoscopy revealed an appendiceal orifice with atypical hyperemia and edema. Subsequent imaging and biopsy results suggested an appendiceal tumor, prompting laparoscopic ileocecal resection. Intraoperative findings revealed an unremarkable appendix, but histopathological analysis unveiled appendiceal duplication, characterized by bifurcation into two lumens within a thick serosal wall. The patient was discharged without complications. CONCLUSIONS: This case underscores the importance of recognizing appendix duplication as a rare differential diagnosis for appendiceal tumors. Surgeons should remain vigilant, especially in cases of Type A duplication, where preoperative diagnosis remains challenging. Early identification can avert potential complications and missed congenital anomalies.
