[Benign multicystic peritoneal mesothelioma. A case report. Review of the literature].

The case of a forty-three year old woman is reported. She was operated on for a pelvic abdominal multicystic peritoneal mesothelioma which was discovered at the time of a systematic gynaecological examination. We specify the anatomo-clinical characteristics of multicystic mesothelioma from the 118 cases described in the literature and related in detail the stages of histopathological diagnosis. We question the differential diagnosis with serious ovarian tumours.
