Low-grade appendiceal mucinous neoplasm associated with ulcerative colitis: A case report and literature review

Although the appendix is part of the colon and can serve as a site for UC-CRC development in patients with pancolitis-type UC, identifying appendiceal lesions through routine surveillance comprising colonoscopy alone may be challenging. In patients with pancolitis-type UC, lesions known as LAMN, which are recognized as precursors of appendiceal mucinous adenocarcinoma, may develop, thereby requiring careful monitoring.
