Ruptured Appendiceal Diverticula Mimicking Low-grade Appendiceal Mucinous Neoplasms
American Journal of Surgical Pathology, 2009Low-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 ...
