Appendiceal mucinous neoplasms: Optimizing treatment strategies based on clinical, histological, and molecular features

Figure 2 Macroscopic and microscopic findings. A: Macroscopic view of a low-grade appendiceal mucinous neoplasm (LAMN), showing cystic dilation of the appendix filled with mucinous content; B: Microscopic view of a LAMN with hematoxylin & eosin staining (× 40 magnification), showing a mucosal surface lined by a single layer of mucin-producing columnar epithelium without high-grade cytologic atypia; C: Additional microscopic view of a LAMN with hematoxylin & eosin staining (× 40 magnification), highlighting features similar to panel B.
