Pseudo-Meigs syndrome in association with primitive peritoneal tumor

We report the case of a 61-year old woman presented with a voluminous centro-pelvic mass (22 × 17 cm), hydrothorax and ascites. Serum CA-125 was high (11,000 UI/ml). An explorative laparotomy located the mass between the rectum and the posterior wall of the uterus. The histological examination showed a primitive peritoneal tumor with serous and endometrioid differentiations. There was a left ovarian metastasis and both peritoneal and pleural liquids revealed no sign of malignancy. After the incomplete surgery, the hydrothorax and ascites decreased considerably. This association of Pseudo-Meigs’ syndrome with primitive peritoneal tumor is uncommon. To our knowledge this is the first case described through a Medline search.
