Rare diffuse peritoneal malignant neoplasms: CT findings in two cases [PDF]

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.

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 ...
