A rare case of low-grade appendiceal mucinous neoplasm within an incarcerated Amyand’s hernia

Abstract

Introduction: We report a rare case of lowgrade appendiceal mucinous neoplasm (LAMN) within an incarcerated Amyand's hernia. Case Report: The patient was admitted for an elective surgery due to an asymptomatic rightsided inguinal hernia. The operative findings were suggestive of an appendiceal mucocele. Appendectomy and herniorrhaphy were performed. The histology report revealed a lowgrade appendiceal mucinous neoplasm. The patient had no clinical, biochemical or imaging signs of disease or hernia recurrence two years postoperatively. Conclusion: Surgical treatment involves appendectomy and hernia repair, which is performed without the implantation of synthetic mesh. The possibility of finding an incidental neoplasm should be considered during the surgery of an Amyand's hernia.
