  • tumors
  • mucinous tumors of the ovary have also been implicated, although in most cases ovarian involvement is favored to be a metastasis from an appendiceal or other gastrointestinal source. (wikipedia.org)
  • Odze and Goldblum, Surgical Pathology of the GI Tract, Liver, Biliary Tract and Pancreas, 2nd ed.) also use the term mucinous adenocarcinoma when referring to low-grade, well-differentiated tumors lacking high-grade features. (wikipedia.org)
  • While the majority of these cases are associated with appendiceal carcinomas, other conditions may also be found, including disseminated peritoneal adenomucinosis (DPAM), peritoneal carcinomas, several mucinous tumors (mucinous adenocarcinoma, mucinous cystadenoma, and mucinous cystadenocarcinoma), as well as other disease states. (wikipedia.org)
  • In contrast to some of the other cyst-forming tumors of the pancreas (such as the intraductal papillary mucinous neoplasm and the mucinous cystic neoplasm), serous cystic neoplasms are almost always entirely benign. (wikipedia.org)
  • cancer
  • Low-grade mucinous adenocarcinoma is used by the American Joint Committee on Cancer and World Health Organization and is nearly or completely synonymous with the DPAM designation. (wikipedia.org)
  • features
  • proposed separating pseudomyxoma peritonei cases into two diagnostic categories: adenoma (disseminated peritoneal adenomucinosis, DPAM) or carcinoma (peritoneal mucinous carcinomatosis, PMCA) with a third category reserved for cases with intermediate features. (wikipedia.org)
  • Cases of PMCA were characterized by peritoneal lesions composed of more abundant mucinous epithelium with the architectural and cytologic features of carcinoma (irregular cells, evidence that cells were rapidly dividing, and other criteria), with or without an associated primary mucinous adenocarcinoma. (wikipedia.org)
  • peritoneal mucinous
  • proposed separating pseudomyxoma peritonei cases into two diagnostic categories: adenoma (disseminated peritoneal adenomucinosis, DPAM) or carcinoma (peritoneal mucinous carcinomatosis, PMCA) with a third category reserved for cases with intermediate features. (wikipedia.org)
  • epithelium
  • In this classification system, cases of DPAM were characterized by peritoneal lesions composed of abundant extracellular mucin containing scant simple to focally proliferative mucinous epithelium with little cytologic atypia or mitotic activity (in other words, most cells looked fairly normal and there was no evidence of mitosis which would indicate that cells were rapidly dividing), with or without an associated appendiceal mucinous adenoma.
