What is a low grade mucinous neoplasm of appendix?
Low-grade appendiceal mucinous neoplasm (LAMN) is a tumour that starts from the mucin-producing cells in the appendix. These tumours often produce swelling or enlargement of the appendix as the abnormal mucin-producing cells cause the appendix to become filled with mucin.
