Epithelial Appendiceal Neoplasms

The Cancer Journal, 2009
The appendiceal malignancies usually arise within a mucocele. The tumor within this structure can be minimally aggressive or of an invasive character. If a low-grade appendiceal malignancy is removed intact, recurrence does not occur. If rupture of the wall of the mucocele occurs with either low-grade or high-grade disease, the epithelial cells within ...

Appendiceal Mucinous Neoplasms

The American Journal of Surgical Pathology, 2003
The classification of appendiceal mucinous tumors is controversial and terminology used for them inconsistent, particularly when they lack overtly malignant features but are associated with extra-appendiceal spread. We reviewed 107 appendiceal mucinous neoplasms and classified them as low-grade appendiceal mucinous neoplasm (LAMN) (n = 88), mucinous ...

Ruptured Appendiceal Diverticula Mimicking Low-grade Appendiceal Mucinous Neoplasms

American Journal of Surgical Pathology, 2009
Low-grade appendiceal mucinous neoplasms may rupture and seed the peritoneum with bland neoplastic mucinous epithelium resulting, when grossly evident, in the well-known process pseudomyxoma peritonei. Appendiceal diverticula may also rupture, resulting in mucin on the appendiceal serosa, which may raise concern for an underlying appendiceal mucinous ...

Israel journal of medical sciences, 1994
A retrospective review of the files of 1,740 appendectomies performed during a 10-year period disclosed 13 patients (0.7%) with primary appendiceal tumors. Adenocarcinoma of the appendix was diagnosed in 6 patients (0.3%), which is a two- to four-fold higher incidence than reported in the literature.
