Meigs' syndrome in association with a locally invasive adenocarcinoma of the fallopian tube.

A patient with recurrent pleural effusions posed a diagnostic challenge. The pleural aspirate CA-125 assay was markedly elevated which indicated a primary ovarian pathologic process. However, in this case a rare fallopian tube adenocarcinoma was the underlying problem. Meigs' syndrome can resemble a metastatic pelvic carcinoma in its presentation, but the prognosis is much more favourable when the syndrome is associated with a benign ovarian tumour.
