Comparative study of mucinous and non-mucinous appendiceal neoplasms with peritoneal dissemination treated by cyoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC).

European Journal of Surgical Oncology, 2020
BACKGROUND Appendiceal non-mucinous neoplasms (AnMN) are rare and poorly understood malignancies with no standard treatment. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is largely used to treat peritoneal ...

Long-term outcomes for patients with peritoneal acellular mucinosis secondary to low grade appendiceal mucinous neoplasms.

European Journal of Surgical Oncology, 2020
INTRODUCTION Low grade appendiceal mucinous neoplasms (LAMN) are known to metastasise to the peritoneum resulting in pseudomyxoma peritonei (PMP).

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 ...

Pathogenesis of histologic variations of appendiceal mucinous neoplasms.

European Journal of Surgical Oncology, 2023
BACKGROUND In order for peritoneal metastases from a primary appendiceal mucinous neoplasm to occur, the wall of the appendix must perforate to allow mucus with tumor cells access to the peritoneal spaces.

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.
