Abstract

Pseudomyxoma peritonei (PMP) is classified into pathologically and prognostically distinct categories, such as disseminated peritoneal adenomucinosis (DPAM) and peritoneal mucinous carcinomatosis. There is overwhelming evidence that DPAM arises from a mucinous adenoma of the appendix. The one exception to this is the presentation of a mature ovarian cystic teratoma as PMP where the appendix is normal. This report describes such a case and discusses the presentation, histopathology, and treatment options.

  • CK, cytokeratin
  • DPAM, disseminated peritoneal adenomucinosis
  • PMCA, peritoneal mucinous carcinomatosis
  • PMP, pseudomyxoma peritonei
  • pseudomyxoma peritonei
  • ovarian cystic teratoma
  • appendiceal mucinous adenoma
  • disseminated peritoneal adenomucinosis
