Which classification system defines best prognosis of mucinous neoplasms of the appendix with peritoneal dissemination: TNM vs PSOGI?

Journal of Clinical Pathology, 2021
Aims Several classification systems are used for pseudomyxoma peritonei. The four-tiered classification system proposed by Peritoneal Surface Oncology Group International (PSOGI) and the two-tiered proposed by the eighth edition of the American Joint ...

Polypoid peritoneal metastases from carcinoid neoplasms

Human Pathology, 1984
Two cases of lethal carcinoid neoplasia that involved unusual polypoid intraperitoneal metastases rather than the usual flat, sclerotic foci are reported. This type of intraperitoneal polypoid carcinomatosis should alert both the surgeon and pathologist to the possibility of carcinoid neoplasia.

Primary Neoplasms of Peritoneal and Sub-peritoneal Origin: CT Findings

RadioGraphics, 2005
Peritoneal carcinomatosis is a common metastatic manifestation of many organ-based malignancies, particularly carcinomas of the gastrointestinal tract and ovaries. Primary neoplasms of peritoneal and sub-peritoneal origin occur much less frequently than metastatic peritoneal involvement from a known or occult primary tumor; however, these rare primary ...

Benign multicystic peritoneal mesothelioma mimicking mucinous ovarian neoplasm with pseudomyxoma peritonei

BMJ Case Reports, 2023
Cystic mesothelioma, also known as benign multicystic peritoneal mesothelioma (BMPM), is a rare neoplasm and one of the five main histological types of peritoneal mesothelioma. Although it is usually considered benign histologically, it is increasingly accepted as a ‘borderline malignancy’ because the local recurrence rate is high. It is more common in

Discordant Histology of Primary Appendiceal Adenocarcinoid Neoplasms with Peritoneal Dissemination

Annals of Surgical Oncology, 2008
Adenocarcinoid is a rare appendiceal tumor that shows histologically both epithelial and neuroendocrine components. We observed that some patients have peritoneal dissemination, which shows adenocarcinoma but lacks the neuroendocrine histology. The objective of the present study was to quantitate these discordant histopathological findings and examine ...

Rare diffuse peritoneal malignant neoplasms: CT findings in two cases

Abdominal Imaging, 2003
In the peritoneal cavity, diffuse serosal replacement by tumor is demonstrated usually by extensive carcinomatous involvement from gastric, colonic, or pancreatic tumors or less frequently by mesothelioma. Primary tumors other than mesothelioma are extremely rare in the peritoneum.

Treatment and Management of Peritoneal Spread from Appendiceal Neoplasms

Surgical Oncology Clinics of North America
Appendiceal neoplasms are rare entities prone to direct peritoneal spread. As these neoplasms occur in few patients, research regarding their management is largely retrospective, limiting its utility. Classification of these neoplasms continues to evolve and is largely based on histopathology.
