A Low-Grade Appendiceal Mucinous Neoplasm Mimicking a Hydrosalpinx: A Case Report and Review of the Literature

Introduction: A Low-Grade Mucinous Neoplasm (LAMN), formerly known as “mucocele” or “cystadenoma,” is a non-invasive and rare appendiceal tumor, representing 0.2-0.7% of all appendix specimens. Case Report: A 31-year-old female patient who was suffering from chronic right lower quadrant abdominal pain was submitted to an exploratory laparotomy for a presumed right hydrosalpinx. A low-grade mucinous neoplasm of the appendix was discovered and the patient underwent an appendectomy. Discussion: A review of the current literature was performed regarding LAMNs. Conclusion: Further evidence is required in order to address the controversial issues of the pre-operative diagnosis of a LAMN, the extent of surgery performed and the questions regarding fertility preservation in young women.
