It was historically classified under "carcinoma of unknown primary" (CUP). Primary peritoneal cancer (PPC, or PPCa) is a cancer of the cells lining the peritoneum, or abdominal cavity. Some studies indicate that up to 15% of serous ovarian cancers are thought to be actually primary peritoneal carcinomas in origin. Histomorphological and molecular biological characteristics suggest that serous carcinomas, which include ovarian serous carcinoma, uterine serous carcinoma, Fallopian tube serous carcinoma, cervical serous carcinoma, and primary peritoneal serous carcinoma really represent one entity. ==Theory== Ovarian and peritoneal epithelium share common embryonal origin, the coelomic epithelium (mesodermal origin). Coelomic epithelium is thought to be of mesonephric origin. With the overall point being that normal ovarian and peritoneal tissue is derived from the mesonephros. On the contrary, fallopian tube epithelium, endometrium and endocervix are related to paramesonephros (Müllerian duct). Surprisingly, epithelial ovarian cancer and primary peritoneal cancer are histologically similar to the Mullerian epithelium; not their embryonal origin, the mesonephros. Either a metaplasia has occurred or Mullerian remnants have been left behind in coelemic epithelium, which have turned oncogenic. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Primary peritoneal carcinoma」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
