Abstract excerpt

AIMS: We identified three extra-appendiceal low-grade appendiceal mucinous neoplasms (LAMN)-like lesions occurring in the absence of appendiceal involvement, raising uncertainty regarding their classification, biologic nature, and clinical significance. METHODS: We identified three cases of LAMN-like lesions arising in duplication cysts, anatomically separate from the appendix. These cases were evaluated by...
