Molecular and clinicopathological features of appendiceal mucinous neoplasms

Virchows Archiv, 2020
Appendiceal mucinous tumors (AMTs) include low-grade mucinous appendiceal neoplasms (LAMNs), high-grade mucinous appendiceal neoplasms (HAMNs), and mucinous adenocarcinomas (MACs). We collected 51 AMT samples (LAMN: 34, HAMN: 8, MAC: 9). Three of the eight HAMN cases contained LAMN components, and four out of nine MAC cases contained LAMN and/or HAMN ...

Prognostic Significance of Localized Extra-appendiceal Mucin Deposition in Appendiceal Mucinous Neoplasms

American Journal of Surgical Pathology, 2009
Appendiceal mucinous neoplasms confined to the mucosa are benign, whereas those with disseminated peritoneal mucin deposits often follow an indolent, but malignant, course. Not infrequently, appendiceal mucinous neoplasms are associated with localized periappendiceal mucin deposits, but lack diffuse peritoneal involvement. Mucin deposits in these cases

Incidence and Survival of Appendiceal Mucinous Neoplasms

American Journal of Clinical Oncology, 2017
Objectives:The aim of this study is to characterize the changes in the incidence, presentation, surgical treatment, and survival of patients with appendiceal mucinous neoplasm (AMN) over the past 4 decades using nationwide cancer surveillance data.Methods:Patients with the diagnosis of AMN were identified in the Surveillance Epidemiology and End ...

Mucinous appendiceal neoplasms: classification, imaging, and HIPEC

Abdominal Radiology, 2019
Recent advances, specifically cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC), offer advantages compared to the traditional therapeutic approach of systemic chemotherapy in the treatment of peritoneal carcinomatosis from mucinous appendiceal neoplasms (MAN).

The Impact of Preoperative Colonoscopy for Appendiceal Mucinous Neoplasms

Annals of Surgical Oncology
Preoperative colonoscopy is recommended for colorectal cancers to exclude synchronous tumors. However, data are lacking regarding this recommendation for appendiceal mucinous neoplasms. This study evaluated whether preoperative colonoscopy in patients with appendiceal mucinous lesions would reveal a significant finding, modify the operative plan, or be

Exploring the mysterious mucinous appendiceal neoplasm

Seminars in Diagnostic Pathology
Mucinous neoplasms of the appendix comprise a group of diagnostically challenging lesions that have generated significant controversy and confusion throughout the years, given their potential for aggressive behavior despite very bland cytologic features.

[Sixteen Cases of Appendiceal Mucinous Neoplasm].

Gan to kagaku ryoho. Cancer & chemotherapy, 2023
Appendiceal mucinous neoplasm is a relatively rare disease. It is classified as mucinous adenocarcinoma(MACA)and low- grade appendiceal mucinous neoplasm(LAMN). We retrospectively evaluated 16 cases of appendiceal mucinous neoplasm (LAMN: 13 cases, MACA: 3 cases)that were surgically resected in our hospital between January 2010 and July 2021.

Nonneoplastic Mimics of Appendiceal Mucinous Neoplasms

AJSP: Reviews and Reports, 2019
Abstract With the widespread acceptance of the term low-grade appendiceal mucinous neoplasm (LAMN) for relatively bland mucinous tumors of the appendix with pushing invasion and a propensity to disseminate to the peritoneal cavity, there has been increasing concern among pathologists of overlooking one of these tumors when an appendix shows ...

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 ...
