• In the present report, we describe a rare case of primary signet ring cell carcinoma of the appendix with ovarian metastasesand unresectable peritoneal dissemination occurring in a 45-year-old female patient. (wjgnet.com)
  • We describe a case of a late recurrence of a mucinous intestinal-type borderline ovarian tumor with disseminated peritoneal adenomucinosis. (web.app)
  • Objective To determine the sonographic findings that distinguish borderline ovarian tumors (BOT) from both benign and invasive malignant tumors, thus allowing. (web.app)
  • Peritoneal mucinous carcinomatosis is characterized by abundant peritoneal mucinous tumor, similar to the clinical presentation of adenomucinosis. (nih.gov)
  • A third group of tumors displays intermediate or discordant histologic features but manifests a clinical course very similar to cases of pure peritoneal carcinomatosis. (nih.gov)
  • 9. Disseminated peritoneal adenomucinosis and peritoneal mucinous carcinomatosis. (nih.gov)
  • We postulated that these mutations might be more frequent in high-grade (HG) PMP (peritoneal mucinous carcinomatosis) versus low-grade (LG) PMP (disseminated peritoneal adenomucinosis/peritoneal mucinous carcinomatosis), for which survival differences are well documented. (nih.gov)
  • At the time of surgery to close a colostomy, a disseminated peritoneal carcinomatosis was noted with no evidence of disseminated disease to other organs. (medscape.com)
  • High peritoneal carcinomatosis index (PCI) is associated with an increased risk of surgical complications. (biomedcentral.com)
  • 19. Pseudomyxoma peritonei in women: a clinicopathologic analysis of 30 cases with emphasis on site of origin, prognosis, and relationship to ovarian mucinous tumors of low malignant potential. (nih.gov)
  • The first recommendation would have been to biopsy 1 of these nodules at the time of surgery to rule out a disseminated peritoneal adenomucinosis or pseudomyxoma peritonei. (medscape.com)
  • Disseminated peritoneal adenomucinosis is characterized by copious mucinous ascites (the classical clinical syndrome of PMP) and histologically bland peritoneal mucinous tumors. (nih.gov)
  • However, microscopically, the peritoneal tumors have the architectural and cytologic features of carcinoma, are derived from gastrointestinal mucinous adenocarcinomas, and are associated with a significantly worse prognosis than cases of adenomucinosis. (nih.gov)
  • Morphologic, immunohistochemical, and molecular studies support the interpretation that the ovarian tumors are secondary and that adenomucinosis is of appendiceal origin in women as well as men. (nih.gov)
  • Therefore, primary ovarian mucinous tumors should be classified as either benign or malignant. (nih.gov)
  • 6. Ovarian tumors of borderline malignancy (tumors of low malignant potential): a critical appraisal. (nih.gov)
  • 8. Ovarian mucinous borderline tumors of intestinal type without intraepithelial carcinoma: are they still tumors of low malignant potential? (nih.gov)
  • 12. Mucinous borderline and malignant tumors of the ovary. (nih.gov)
  • Uterine smooth muscle tumors are the most common tumors of the female genital tract and include leiomyoma (LM) and its variants, smooth muscle tumors of uncertain malignant potential (STUMP), and leiomyosarcoma (LMS). (bvsalud.org)
  • Diffuse peritoneal adenomucinosis (DPAM) variant of PMP arising from a ruptured ovarian primary MCT after malignant transformation to a low-grade appendiceal-like mucinous neoplasm was ultimately confirmed. (bvsalud.org)
  • Two of 4 lymph nodes were positive, there was serosal extension, and approximately 6 peritoneal implants were noted locally in the sigmoid peritoneum. (medscape.com)
  • PMP syndrome arising from malignant transformation of an ovarian primary mature cystic teratoma (MCT) is a pathogenesis rarely encountered. (bvsalud.org)
  • The peritoneal cancer index (PCI) [ 8 ] is a quantitative measure that describes the extent of peritoneal disease at surgery. (biomedcentral.com)
  • Due to the more indolent nature of low-grade PMP compared to other peritoneal malignancies, our group has developed a two-step surgical approach for the curative treatment of patients with very high PCI in order to decrease the morbidity and mortality associated with the procedure and to offer a better alternative than debulking alone to patients with unresectable disease. (biomedcentral.com)
  • However, during surgery to reanastomose his colostomy, several hundred small peritoneal implants were noted (95% were 2-3 mm in size), mostly in the upper abdominal quadrants. (medscape.com)
