A Giant Low-Grade Appendiceal Mucinous Neoplasm in a Middle-Aged Female: A Case Report and Review of Literature

Abstract

Appendiceal mucoceles represent abnormal accumulation of mucin in the appendix. They are rare and can be due to neoplastic and nonneoplastic causes, the most common cause being low-grade appendiceal mucinous neoplasm (LAMN), also known as mucinous cystadenoma of the appendix. We present the case of a 48-year-old woman who had complaints of abdominal pain for 2 months. Imaging showed mucocele of the appendix. She was taken for open appendectomy which revealed a huge (16.5 × 7 × 6 cm) mucocele, and histology proved it to be a LAMN with negative margins.
