Year: 2025
Type: article
Study design: Case Report
Abstract: Appendiceal mucinous tumours are rare and can cause various complications, but to the best of our knowledge, there have been no reports of cases leading to secondary appendiceal autoamputation. Appendiceal autoamputation is the detachment of part of the appendix without surgery or other invasive interventions and is rarely observed in clinical settings. The present study reports the case of a 68-year-old male patient who was admitted to the hospital due to right lower abdominal pain and was consequently diagnosed with a periappendiceal abscess and underwent conservative anti-inflammatory drug treatment, which successfully improved the condition of the patient. Laparoscopic appendectomy was conducted 3 months later, during which the appendix was found to have partially separated; postoperative pathology revealed an appendiceal mucinous tumour. Following pathological confirmation of the diagnosis, right hemicolectomy, resection of the greater omentum and partial peritoneal resection were performed, followed by hyperthermic intraperitoneal chemotherapy in accordance with current treatment guidelines. The patient recovered well and was discharged following the operation. Considering the condition of the patient, appendiceal autoamputation was thought to be caused by the appendiceal mucinous tumour. The present case highlights the diagnostic challenges of appendiceal mucinous tumours and underscores the early standardized treatment to improve prognosis.
