[Mucinous metaplasia of fallopian tube mucous membrane as a cause of pseudomyxoma peritonei].

A woman aged 49 years was relaparotomized at the Gynaecological Department of the "Rudolf Virchow" Medical Centre of the Free University of Berlin, following diagnosis of metastatic mucinous adenocarcinoma. Proliferative mucinous metaplasia of the Fallopian tube and consecutive peritoneal pseudomyxoma were established as clinical findings and were hypothetically attributed to mucinous metaplasia of the salpingofimbrial mucosa. Neither mucocele of the appendix nor ovarian tumour were found. This possible site origin has been rarely mentioned in any case report in the past.
