[Pseudomyxoma peritonei caused by proliferating mucinous adenoma of the fimbria mucosa].

Omentectomy was conducted on a 49 year old patient at the Dept. of Surgery of the UFK Berlin-Charlottenburg because of a mucinous adenocarcinoma, without prior detection of the primary tumour site. Relaparotomy revealed proliferative mucinous adenoma of the Fallopian tube and a consecutive pseudomyxoma peritonei. Up to now, this seems to be the first case report of a mucinous adenoma of the Fallopian tube.
