The pleural effusion in ovarian tumors: Often a diagnosis challenge.

Pleural effusions associated with ovarian tumors are not always malignant. Neoplastic etiology of pleural efussion needs histopathological confirmation. We present three cases that illustrate various etiologies for pleural effusions in patients with ovarian tumors: thromboembolism, malignancy and Meigs syndrome. For these patients, it is essential to establish the correct etiology of the pleurisy, since it may change the therapeutic approach. All the cases must be carefully assessed and all the efforts must be done by a multidisciplinary team in order to offer the best solution for each case.
